Practical Pearls

Practice Gap

Dermatology residents can struggle with surgical closure early in their training years. Although experienced dermatologic surgeons may intuitively be able to align edges for maximal cosmesis, doing so can prove challenging in the context of learning basic surgical techniques for early residents.

Furthermore, local anesthesia can distort cutaneous anatomy and surgical landmarks, requiring the surgeon to reexamine their closure technique. Patients may require position changes or may make involuntary movements, both of which require dynamic thinking and planning on the part of the dermatologic surgeon to achieve optimal outcomes.

The Technique

We propose the use of sutures to intraoperatively guide placement of the dermal needle. This technique can be used for various closure types; here, we demonstrate its use in a standard elliptical excision.

To begin, a standard length to width ellipse ratio of 3:1 is drawn with appropriate margins around a neoplasm.¹ After excision and appropriate undermining of the ellipse, we typically use deep sutures to close the deep space. The first pass of the needle through tissue can be performed in a place of the surgeon’s preference but typically abides by the rule of halves or the zipper method (Figure 1A). To determine optimal placement of the second needle pass through tissue, we recommend applying gentle opposing traction forces to the wound apices to approximate the linear outcome of the wound edges. The surgeon can use a skin hook to guide placement of the needle to the contralateral wound edge in an unassisted method of this technique (Figure 1B). The surgeon’s assistant also can aid in applying cutaneous traction along the length of the excision if the surgeon wishes to free their hands (Figure 1C). Because the risk of needlestick injury at this step is small, it is prudent for the surgeon to advise the assistant to avoid needlestick injury by keeping their hands away from the needle path in the surgical site.

Although traction is being applied to the wound apices, the deep suture should extend across the wound with just enough pressure to leave a serosanguineous notched mark in the contralateral tissue edge (Figure 1D). After releasing traction on the wound edges, the surgeon can effortlessly visualize the target for needle placement and make a throw through the tissue accordingly.

This process can be continued until wound closure is complete (Figure 2). Top sutures or adhesive strips can be placed afterward for completing approximation of the wound edges superficially.

Practice Implications

By using this technique to align wound edges intraoperatively, the surgeon can have a functional guide for needle placement. The technique allows improvement of function and cosmesis of surgical wounds, while also accounting for topographical variations in the patient’s surgical site. Approximation of the wound edges is particularly important at the beginning of closure, as the wound edges align and approximate more with each subsequent stitch, with decreasing tension.²

In addition, when operating on a curvilinear or challenging topographical surface of the body, this technique can provide a clear template for guiding suture placement for approximating wound edges. Furthermore, local biodynamic anatomy might become distorted after excision of the tissue specimen due to release of centripetal tangential forces that were present in the pre-excised skin.¹ Local change in biodynamic forces may be difficult to plan for preoperatively using other techniques.³

Although this technique can be utilized for all suture placements in closure, it is of greatest value when placing the first few sutures and when operating on nonplanar surfaces that might become distorted after excision. To ensure the best outcome, it is important to be certain that the area has been properly cleaned prior to surgery and a sterile technique is used.

Mycologic testing is necessary and cost-effective¹ for appropriate diagnosis and treatment of onychomycosis. Empiric treatment of onychodystrophy for presumed onychomycosis can result in misdiagnosis, treatment failure, or potential adverse effects caused by medications.² Collection of ample subungual debris facilitates the sensitivity and specificity of fungal culture and fungal polymerase chain reaction. However, the naturally pale hue of subungual debris makes specimen estimation challenging, particularly when using a similarly light-colored gauze or piece of paper for collection (Figure, A).

The Technique

A sheet from a black sticky notepad (widely available and cost-effective) can be adapted for making a diagnosis of onychomycosis (Figure, B).

Practical Implication

Use of a dark background that contrasts with light-hued nail debris is valuable to ensure an adequate specimen for fungal culture and polymerase chain reaction.

Perioperative anxiety is common in patients undergoing nail surgery. Patients might worry about seeing blood; about the procedure itself, including nail avulsion; and about associated pain and disfigurement. Nail surgery causes a high level of anxiety that correlates positively with postoperative pain¹ and overall patient dissatisfaction. Furthermore, surgery-related anxiety is a predictor of increased postoperative analgesic use² and delayed recovery.³

Therefore, implementing strategies that reduce perioperative anxiety may help minimize postoperative pain. Squeezing a stress ball, hand-holding, virtual reality, and music are tools that have been studied to reduce anxiety in the context of Mohs micrographic surgery; these strategies have not been studied for nail surgery.

The Technique

Using a sleep mask is a practical solution to reduce patient anxiety during nail surgery. A minority of patients will choose to watch their surgical procedure; most become unnerved observing their nail surgery. Using a sleep mask diverts visual attention from the surgical field without physically interfering with the nail surgeon. Utilizing a sleep mask is cost-effective, with disposable sleep masks available online for less than $0.30 each. Patients can bring their own mask, or a mask can be offered prior to surgery.

If desired, patients are instructed to wear the sleep mask during the entirety of the procedure, starting from anesthetic infiltration until wound closure and dressing application. Any adjustments can be made with the patient’s free hand. The sleep mask can be offered to patients of all ages undergoing nail surgery under local anesthesia, except babies and young children, who require general anesthesia.

Practical Implications

Distraction is an important strategy to reduce anxiety and pain in patients undergoing surgical procedures. In an observational study of 3087 surgical patients, 36% reported that self-distraction was the most helpful strategy for coping with preoperative anxiety.⁴ In a randomized, open-label clinical trial of 72 patients undergoing peripheral venous catheterization, asking the patients simple questions during the procedure was more effective than local anesthesia in reducing the perception of pain.⁵

It is crucial to implement strategies to reduce anxiety in patients undergoing nail surgery. Using a sleep mask impedes direct visualization of the surgical field, thus distracting the patient’s sight and attention from the procedure. Furthermore, this technique is safe and cost-effective.

Controlled clinical trials are necessary to assess the efficacy of this method in reducing nail surgery–related anxiety in comparison to other techniques.

Management of surgical wounds is a critical component of postsurgical care for patients during recovery at home.¹ However, postoperative wound care can be troublesome, time consuming, and expensive. Common problems with current standard dressings include an increased risk for infection, pain, and wound damage with frequent dressing changes.^2-4

Patients often are unable to take proper care of wounds themselves and may not have the financial means or social support to have others assist them.^4-6 For these patients, the option of a hassle-free dressing that they can leave on until their follow-up appointment is preferred. In our experience, what we call a 24-7 bandage has been remarkably successful in patients who are vulnerable to wound complications.

We report a comfortable, effective, and simple technique for wound dressings after dermatologic surgery.

The Technique

In Figure 1, we demonstrate a simple dressing technique that can be used to optimize wound healing in patients unable to provide adequate wound care for themselves:

1. The surgical site is covered with mupirocin ointment, followed by bismuth tribromophenate gauze (Figure 1A). The bismuth-impregnated gauze helps make the dressing nonadherent and moderately occlusive. It also adds moisture to the wound bed.

2. The gauze is then covered with excess mupirocin. A nonadherent dressing is applied (Figure 1B).

3. The entire area is covered with gauze and cover-roll nonlatex bandaging tape to ensure maximum adhesion (Figures 1C and 1D).

4. When the surgical site is on an extremity, it is wrapped in a self-adherent wrap or bandage roll to prevent clothing from pulling the tape loose.

Once this dressing technique is performed in the office, the bandage requires no wound care at home other than ensuring that the bandage is kept dry. The 24-7 dressing can be left on the surgical site for 7 days until the follow-up appointment. If necessary, it also can be applied for a second week after bolster removal or for multiple weeks following advanced flap repair.

Our patients find this dressing comfortable and unobtrusive. It is easy for the staff to apply and inexpensive.

Practical Implications

We have treated approximately 200 patients with the 24-7 dressing technique. Our experience is that these patients demonstrated an excellent aesthetic outcome without complications (Figure 2). We have successfully utilized the dressing in several anatomic locations, including the arms, legs, neck, face, and scalp. We use mupirocin for its antimicrobial activity, but we have not performed a study at our clinic looking at the difference between rate of infection and wound healing using mupirocin vs petrolatum. We prefer adding bulk gauze under the tape and leaving the dressing on for 7 days. We seldom have issues with bleeding, and if there is an issue, the patient is told to come back to our clinic so we can change the bandage for them.

This dressing technique is cost-effective to the patient and clinical staff, provides protection from potential injury to the sutures, decreases the risk for infection, and removes the stress and burden on the patient and family of frequent dressing changes. Furthermore, by preventing patient manipulation and frequent removal of the dressing, the wound retains adequate moisture during healing. This technique also can be applied to a variety of outpatient procedures other than Mohs micrographic surgery.

We hope that our colleagues find this 24-7 dressing technique for dressing wounds after dermatologic surgery useful in patient populations vulnerable to wound complications.

Tuberous sclerosis complex (TSC) is an autosomal-dominant genetic disorder resulting in loss-of-function mutations in the TSC1 and TSC2 genes. These mutations lead to constitutive activation of the mitogenic mTOR pathway and release of lymphangiogenic growth factors, causing the formation of hamartomatous tumors throughout multiple organ systems.¹ Facial angiofibromas (FAs) are a common cutaneous manifestation of TSC, affecting up to 80% of patients worldwide.² Aesthetic disfigurement, vision obstruction, and breathing impairment often are associated with FAs. They frequently arise in children with TSC and impose a psychosocial burden that can affect the patient’s overall quality of life.

Cutaneous stigmata of TSC pose a significant therapeutic challenge. Topical sirolimus has become a first-line treatment of FAs by inhibiting the mitogenic mTOR pathway¹; however, thicker, more extensive lesions are less responsive to topical therapy. The entire dermis is involved in TSC, and topical sirolimus alone often is ineffective for large fibrous FAs.³ Likewise, oral mTOR inhibition has shown only 25% to 50% improvement in FAs and has potential side effects that can limit patients’ tolerance and compliance.⁴

The Technique

A 46-year-old man with TSC was referred to dermatology for treatment of numerous facial papules and plaques that had been present since childhood and were consistent with FAs (Figure 1A). The lesions were tender, impaired the patient’s breathing, and caused emotional distress. Dermabrasion was attempted 20 years prior with minimal improvement and subsequent progression of the FAs. Other stigmata of TSC were present, including cutaneous hypopigmented macules and shagreen patches as well as seizures and renal angiomyolipomas. Due to multiorgan involvement, the patient was started on once-daily oral everolimus 2.5 mg; however, the FAs were progressive despite the systemic mTOR inhibition. Furthermore, it was presumed that topical sirolimus monotherapy would be ineffective due to thickness and extent of FAs; therefore, we proposed a novel treatment approach combining initial surgical debulking with subsequent longitudinal use of topical sirolimus to reduce the risk of recurrence.

Local anesthesia with lidocaine 1% and epinephrine 1:100,000 was administered. Larger FAs were removed at the base with a sterile surgical blade. Nasal recontouring subsequently was performed using a combination of shave biopsy and curettage. Extensive electrocautery was performed for hemostasis and destruction of residual FAs. Figure 1B shows the immediate postoperative result.

One month postoperatively, the patient stopped the oral everolimus at his oncologist’s recommendation due to abdominal pain and peripheral edema. Once the abraded skin showed evidence of wound healing, the patient was instructed to initiate sirolimus ointment 1% twice daily to reduce the risk of recurrence.^1,5,6 At 8-week follow-up, the patient was noted to have cosmetic improvement and resolution of breathing impairment (Figure 2A). He continued to show excellent cosmetic results at 1-year follow-up using topical sirolimus monotherapy (Figure 2B).

Practical Implications

Surgical debulking combined with longitudinal use of sirolimus ointment 1% can achieve an optimal therapeutic response for disfiguring phymatous presentation of FAs in the setting of TSC. We believe it is an effective approach for thick disfiguring FAs that are unlikely to respond to mTOR inhibition alone.

He continued to show excellent cosmetic results at 1-year follow-up using topical sirolimus monotherapy (Figure 2B).

Practical Implications

Surgical debulking combined with longitudinal use of sirolimus ointment 1% can achieve an optimal therapeutic response for disfiguring phymatous presentation of FAs in the setting of TSC. We believe it is an effective approach for thick disfiguring FAs that are unlikely to respond to mTOR inhibition alone.

Practice Gap

Tuberous sclerosis complex (TSC) is an autosomal-dominant genetic disorder resulting in loss-of-function mutations in the TSC1 and TSC2 genes. These mutations lead to constitutive activation of the mitogenic mTOR pathway and release of lymphangiogenic growth factors, causing the formation of hamartomatous tumors throughout multiple organ systems.¹ Facial angiofibromas (FAs) are a common cutaneous manifestation of TSC, affecting up to 80% of patients worldwide.² Aesthetic disfigurement, vision obstruction, and breathing impairment often are associated with FAs. They frequently arise in children with TSC and impose a psychosocial burden that can affect the patient’s overall quality of life.

Cutaneous stigmata of TSC pose a significant therapeutic challenge. Topical sirolimus has become a first-line treatment of FAs by inhibiting the mitogenic mTOR pathway¹; however, thicker, more extensive lesions are less responsive to topical therapy. The entire dermis is involved in TSC, and topical sirolimus alone often is ineffective for large fibrous FAs.³ Likewise, oral mTOR inhibition has shown only 25% to 50% improvement in FAs and has potential side effects that can limit patients’ tolerance and compliance.⁴

The Technique

A 46-year-old man with TSC was referred to dermatology for treatment of numerous facial papules and plaques that had been present since childhood and were consistent with FAs (Figure 1A). The lesions were tender, impaired the patient’s breathing, and caused emotional distress. Dermabrasion was attempted 20 years prior with minimal improvement and subsequent progression of the FAs. Other stigmata of TSC were present, including cutaneous hypopigmented macules and shagreen patches as well as seizures and renal angiomyolipomas. Due to multiorgan involvement, the patient was started on once-daily oral everolimus 2.5 mg; however, the FAs were progressive despite the systemic mTOR inhibition. Furthermore, it was presumed that topical sirolimus monotherapy would be ineffective due to thickness and extent of FAs; therefore, we proposed a novel treatment approach combining initial surgical debulking with subsequent longitudinal use of topical sirolimus to reduce the risk of recurrence.

Local anesthesia with lidocaine 1% and epinephrine 1:100,000 was administered. Larger FAs were removed at the base with a sterile surgical blade. Nasal recontouring subsequently was performed using a combination of shave biopsy and curettage. Extensive electrocautery was performed for hemostasis and destruction of residual FAs. Figure 1B shows the immediate postoperative result.

One month postoperatively, the patient stopped the oral everolimus at his oncologist’s recommendation due to abdominal pain and peripheral edema. Once the abraded skin showed evidence of wound healing, the patient was instructed to initiate sirolimus ointment 1% twice daily to reduce the risk of recurrence.^1,5,6 At 8-week follow-up, the patient was noted to have cosmetic improvement and resolution of breathing impairment (Figure 2A). He continued to show excellent cosmetic results at 1-year follow-up using topical sirolimus monotherapy (Figure 2B).

Practical Implications

Surgical debulking combined with longitudinal use of sirolimus ointment 1% can achieve an optimal therapeutic response for disfiguring phymatous presentation of FAs in the setting of TSC. We believe it is an effective approach for thick disfiguring FAs that are unlikely to respond to mTOR inhibition alone.

Clinical Challenge

An odontogenic cutaneous sinus tract (OCST) of dental origin is an uncommon occurrence and is most commonly caused by chronic periodontitis, specifically a periapical abscess due to chronic dental infection.^1,2 Odontogenic cutaneous sinus tract commonly is misdiagnosed due to a lack of symptoms on presentation, location, and variations in clinical appearance mimicking other lesions. Patients with OCSTs typically present with a fixed, erythematous, crusty, and nontender nodule with periodic drainage that easily can be mistaken for a pustule, furuncle, cyst, foreign-body lesion, squamous cell carcinoma (SCC), basal cell carcinoma, or granulomatous disorder.³ It becomes challenging for dermatologists to correctly diagnose these lesions and refer for proper evaluation and treatment.

Practice Gap

It is estimated that half of patients with an extraoral fistula are treated with multiple dermatologic surgical operations, radiotherapy, antibiotic therapy, and chemotherapy before the correct diagnosis is made.¹ Thus, proper identification of these lesions is crucial for prognosis and treatment. The most common locations for OCSTs are the mandibular, submandibular, and cervical skin.^1,2 Given these locations, patients with OCSTs commonly present to the dermatology office for evaluation. Education regarding the clinical presentation, histopathology, and proper evaluation and further referral for treatment is essential for dermatologists.

Tools and Technique for Diagnosis

We present 2 patients with OCSTs who were referred for cutaneous surgery for an SCC and epidermal cyst, but the proper diagnosis was rendered after an index of suspicion and clinicopathologic correlation led to additional testing and eventual referral for imaging.

Patient 1
A 68-year-old woman presented for Mohs micrographic surgery (MMS) of a biopsy-proven SCC on the chin. The tumor cleared after 2 MMS stages (Figure 1A). Due to notable inflammation in each stage, the slides were sent to a pathologist who confirmed clear margins. Within 2 weeks of MMS, the wound began to dehisce (Figure 1B). The patient presented 4 months later with a crusted ulcerated nodule at the MMS site (Figure 1C). A biopsy showed likely recurrence of SCC. Upon presentation to the Mohs surgeon, the nodule felt fixed to the underlying jaw, and the patient was noted to have poor dentition. The patient was sent for computed tomography (CT), which showed focal thinning of the mandible, likely postsurgical, and clear maxillary sinuses. Due to the clinical appearance and anatomic location of the lesion, a request was made for a second read of the CT, specifically looking for an OCST at the prior surgical site. With this information, the radiologist noted an OCST extending from the mandible to the lesion, reported as a periapical lucency (representing a periapical abscess) at a mandibular tooth with a dental sinus draining into the soft tissues. The patient was started on antibiotics and referred to an oral surgeon for OCST excision.

Practice Implications

Odontogenic cutaneous sinus tracts commonly are misdiagnosed due to variations in clinical presentations resembling more common cutaneous diagnoses, nonspecific histopathologic findings, and lack of dental symptoms or concerns about dentition. Clinically, an OCST presents as a fixed, red, crusty, nontender nodule with intermittent draining. With palpation of the involved area, the clinician may feel a cord of tissue connecting the skin lesion intraorally.^2,4 A clinician should have a high index of suspicion for an OCST when evaluating fixed lesions of the lower face, jawline, and neck due to the possibility of a dental origin,¹ which is important because an OCST can have similar clinical findings to lesions such as congenital fistulas, pustules, cysts, osteomyelitis, foreign-body granulomas, pyogenic granulomas, syphilis, metastatic carcinomas, basal cell carcinomas, and SCCs.^2,4 A PubMed search of articles indexed for MEDLINE using the terms Mohs, MMS, chemosurgery, odontogenic sinus, odontogenic cutaneous sinus tract, and dental sinus yielded only 2 OCSTs that were referred for MMS in the last 30 years, both of which were in the nasolabial fold/medial malar cheek.^2,4 Histopathologic findings of an OCST are nonspecific; a mixed or granulomatous inflammatory infiltrate, granulation tissue, and scarring can be seen.¹ Pseudocarcinomatous/pseudoepitheliomatous hyperplasia of the epidermis can be seen and cause histologic misinterpretation for an SCC.² Given that these findings are nonspecific without a clinical context, even with a histopathologic diagnosis of SCC or cyst, a clinical suspicion for an OCST should lead to an intraoral examination. Imaging can be ordered to look for an OCST in the area of interest. Although panoramic or periapical radiography with or without dental probes/radiopaque markers commonly have been used, more recent literature has suggested that CT may be superior to radiographs for making an OCST diagnosis.^1,3 If imaging is not consistent with the clinically suspected OCST, we recommend directly contacting the radiologist to explain the clinical history and even refresh his/her suspicion for this diagnosis.

If a diagnosis of an OCST is made, oral antibiotics can be prescribed, though the use of antibiotics has been controversial. For severe odontogenic infections, typically beta-lactam antibiotics, cephalosporins, metronidazole, clindamycin, moxifloxacin, or erythromycin can be given for 7 days or until 3 days after symptoms have resolved.⁵ Although antibiotics can bring temporary resolution, it is imperative to treat the source of infection to prevent recurrence. It is crucial for these patients to be referred to an oral surgeon for evaluation and treatment of OCST by either a root canal or tooth extraction.

Final Thoughts

We present this pearl on the diagnosis and management of an OCST, also known as a dental sinus, to better assist clinicians in making this diagnosis. With an index of suspicion as well as intraoral and radiologic evaluations, a proper diagnosis may be rendered, potentially avoiding unnecessary cutaneous surgery. In addition, we highlight the importance of communication between the clinician and the radiologist to directly look for OCST in the area of concern and consider a re-read of the images when clinical suspicion does not correlate with the radiology report.

Invasive fungal infections are a leading cause of morbidity and mortality among neutropenic, immunocompromised, and critically ill patients. Candida species are the most common cause of fungemia, with portals of entry into the bloodstream including the gastrointestinal tract, contaminated intravascular catheters, and localized foci of infection.¹ Diagnosis of invasive candidiasis remains challenging due to an absence of specific clinical signs and symptoms, varying from a mild fever that is unresponsive to antibiotics to florid sepsis. When present, clinical clues may include chorioretinitis; muscle abscesses; and skin eruptions, characteristically with Candida tropicalis. Cutaneous manifestations of disseminated Candida infections appear in only 13% of affected patients.¹ The lesions typically present as 5- to 10-mm pink dermal papules or painless pustules on an erythematous base and may be singular, localized, or diffuse in distribution. Body regions normally involved are the trunk, arms, and legs, rarely the head and neck.¹ Cutaneous lesions often develop at a time when patients are febrile, are not responding to antibiotics, and are clinically deteriorating.

A 15-year-old adolescent boy with pre–B-cell acute lymphoblastic leukemia was admitted with febrile neutropenia for presumed septic shock secondary to an unknown infectious etiology. The patient was started on broad-spectrum intravenous antibiotics, and blood cultures were obtained. On the second day of hospitalization, he developed approximately 10 to 15 discrete, 3- to 6-mm, pink to violaceous papules scattered on the chest and arms (Figure 1). Over several hours, the number of lesions increased to more than 50 with involvement of the legs (Figure 2). A punch biopsy of lesional skin from the left dorsal wrist demonstrated a circumscribed abscess of yeast in the papillary dermis, which was highlighted by periodic acid–Schiff staining with minimal associated inflammation (Figure 3). Blood and tissue cultures persistently grew C tropicalis. The patient was started on intravenous liposomal amphotericin B but died on day 5 of hospitalization after developing endocarditis.

Early and reliable diagnosis of Candida species fungemia is of critical importance to successful treatment, particularly with the emergence of multidrug-resistant strains such as Candida auris.² In patients with apparent cutaneous manifestations, a lesional punch biopsy for culture and histopathologic evaluation is recommended in addition to blood culture; however, organisms may or may not be present in large numbers, and they may be difficult to identify on routine hematoxylin and eosin–stained tissue sections. To enhance the likelihood of highlighting the fungus within the sample, the pathologist must be made aware of the presumptive diagnosis of disseminated candidiasis so that special techniques can be utilized, such as periodic acid–Schiff stain.

Although positive blood culture is the gold standard for candidemia diagnosis, only 30% to 50% of patients with disseminated candidiasis had positive blood cultures at autopsy.¹ Another study showed the sensitivity of blood culture for the detection of invasive fungal infection to be as low as 8.3%.³ In cases with positive blood cultures, the median time to positivity is 2 to 3 days, but it can take as long as 8 days, thus limiting its clinical utility in acutely ill patients.⁴ Given the low sensitivity and prolonged time required for culture growth of most fungal organisms, novel assays for rapid, non–culture-based diagnosis of systemic fungal infections hold substantial clinical promise moving forward.

The Technique

One of the more promising non–culture-based fungal diagnostic methodologies is an antigen assay based on the detection of serum (1,3)-β-D-glucan (BDG), a major cell wall constituent of most pathogenic fungi. This assay is not specific for Candida species and can be positive for Aspergillosis species, Fusarium species, Coccidioides immitis, Histoplasma capsulatum, and Pneumocystis jirovecii pneumonia, among others; therefore, it functions as a general biomarker for fungi in the bloodstream.^4,5 (1,3)-β-D-glucan assay can be useful as an adjunct for blood cultures and punch biopsy, especially when cultures are negative or the results remain outstanding. The results of the BDG assay are available in less than 24 hours at minimal cost, and the test is approved by the US Food and Drug Administration for use as an aid in invasive fungal disease diagnosis. In a meta-analysis of 11 studies, BDG sensitivity was 75%.⁴ In a study based on autopsy cases from 6 years, BDG specificity was 98.4% with positive and negative predictive values of 86.7% and 97.1%, respectively.³ Optimal results were achieved when 2 consecutive tests were positive.⁴ The serum assay output is based on spectrophotometer readings, which are converted to BDG concentrations (negative, <60 pg/mL; indeterminate, 60–79 pg/mL; positive ≥80 pg/mL).⁵ Although we cannot be certain, utilizing the BDG assay in our patient may have led to earlier treatment and a better outcome.

A disadvantage of the BDG assay is the potential for false-positive results, which have been reported in lung transplant recipients with respiratory mold colonization and patients with other systemic bacterial infections.⁴ False-positive results also have been associated with use of ampicillin-clavulanate and piperacillin-tazobactam antibiotics and human blood products, hemodialysis, and severe mucositis, thus reaffirming the importance of judicious interpretation of BDG assay results by the clinician.^4,6 There also is a potential for false-negative results, as the BDG assay does not detect certain fungal species such as Cryptococcus species and Blastomyces dermatitidis, which produce very low levels of BDG, or zygomycetes (Absidia, Mucor, and Rizopus species), which are not known to produce BDG.⁶

Practice Implications

In the setting of invasive fungal infections, a high degree of clinical suspicion is paramount due to the often subtle nature of cutaneous manifestations. A positive BDG assay can be used to identify high-risk patients for empiric antifungal therapy, prompting early intervention and improved outcomes in these acutely ill patients. The BDG assay’s excellent negative predictive value is useful in ruling out invasive Candida infections and may justify stopping unnecessary empiric antifungal therapy.⁴ For the dermatology hospitalist, incorporation of the BDG assay as a noninvasive screening tool may allow for more rapid initiation of appropriate antifungal therapy while awaiting confirmatory skin biopsy or culture results in disseminated candidemia and other invasive fungal infections.

Over several hours, the number of lesions increased to more than 50 with involvement of the legs (Figure 2). A punch biopsy of lesional skin from the left dorsal wrist demonstrated a circumscribed abscess of yeast in the papillary dermis, which was highlighted by periodic acid–Schiff staining with minimal associated inflammation (Figure 3). Blood and tissue cultures persistently grew C tropicalis. The patient was started on intravenous liposomal amphotericin B but died on day 5 of hospitalization after developing endocarditis.

Early and reliable diagnosis of Candida species fungemia is of critical importance to successful treatment, particularly with the emergence of multidrug-resistant strains such as Candida auris.² In patients with apparent cutaneous manifestations, a lesional punch biopsy for culture and histopathologic evaluation is recommended in addition to blood culture; however, organisms may or may not be present in large numbers, and they may be difficult to identify on routine hematoxylin and eosin–stained tissue sections. To enhance the likelihood of highlighting the fungus within the sample, the pathologist must be made aware of the presumptive diagnosis of disseminated candidiasis so that special techniques can be utilized, such as periodic acid–Schiff stain.

Although positive blood culture is the gold standard for candidemia diagnosis, only 30% to 50% of patients with disseminated candidiasis had positive blood cultures at autopsy.¹ Another study showed the sensitivity of blood culture for the detection of invasive fungal infection to be as low as 8.3%.³ In cases with positive blood cultures, the median time to positivity is 2 to 3 days, but it can take as long as 8 days, thus limiting its clinical utility in acutely ill patients.⁴ Given the low sensitivity and prolonged time required for culture growth of most fungal organisms, novel assays for rapid, non–culture-based diagnosis of systemic fungal infections hold substantial clinical promise moving forward.

The Technique

One of the more promising non–culture-based fungal diagnostic methodologies is an antigen assay based on the detection of serum (1,3)-β-D-glucan (BDG), a major cell wall constituent of most pathogenic fungi. This assay is not specific for Candida species and can be positive for Aspergillosis species, Fusarium species, Coccidioides immitis, Histoplasma capsulatum, and Pneumocystis jirovecii pneumonia, among others; therefore, it functions as a general biomarker for fungi in the bloodstream.^4,5 (1,3)-β-D-glucan assay can be useful as an adjunct for blood cultures and punch biopsy, especially when cultures are negative or the results remain outstanding. The results of the BDG assay are available in less than 24 hours at minimal cost, and the test is approved by the US Food and Drug Administration for use as an aid in invasive fungal disease diagnosis. In a meta-analysis of 11 studies, BDG sensitivity was 75%.⁴ In a study based on autopsy cases from 6 years, BDG specificity was 98.4% with positive and negative predictive values of 86.7% and 97.1%, respectively.³ Optimal results were achieved when 2 consecutive tests were positive.⁴ The serum assay output is based on spectrophotometer readings, which are converted to BDG concentrations (negative, <60 pg/mL; indeterminate, 60–79 pg/mL; positive ≥80 pg/mL).⁵ Although we cannot be certain, utilizing the BDG assay in our patient may have led to earlier treatment and a better outcome.

A disadvantage of the BDG assay is the potential for false-positive results, which have been reported in lung transplant recipients with respiratory mold colonization and patients with other systemic bacterial infections.⁴ False-positive results also have been associated with use of ampicillin-clavulanate and piperacillin-tazobactam antibiotics and human blood products, hemodialysis, and severe mucositis, thus reaffirming the importance of judicious interpretation of BDG assay results by the clinician.^4,6 There also is a potential for false-negative results, as the BDG assay does not detect certain fungal species such as Cryptococcus species and Blastomyces dermatitidis, which produce very low levels of BDG, or zygomycetes (Absidia, Mucor, and Rizopus species), which are not known to produce BDG.⁶

Practice Implications

In the setting of invasive fungal infections, a high degree of clinical suspicion is paramount due to the often subtle nature of cutaneous manifestations. A positive BDG assay can be used to identify high-risk patients for empiric antifungal therapy, prompting early intervention and improved outcomes in these acutely ill patients. The BDG assay’s excellent negative predictive value is useful in ruling out invasive Candida infections and may justify stopping unnecessary empiric antifungal therapy.⁴ For the dermatology hospitalist, incorporation of the BDG assay as a noninvasive screening tool may allow for more rapid initiation of appropriate antifungal therapy while awaiting confirmatory skin biopsy or culture results in disseminated candidemia and other invasive fungal infections.

Anxiety is common in patients undergoing surgery with general anesthesia and may be exacerbated in patients undergoing dermatologic surgery with local anesthesia. Apprehension might be worse for nail surgery patients because the nail unit is highly innervated and vascular. Many patients fear the anesthetic injections, and there often is pain postoperatively. Perioperative anxiety correlates with increased postoperative pain,¹ analgesic use,² and delayed recovery.³ Several alternatives have been proposed to decrease perioperative anxiety, including nonpharmacologic interventions such as using educational videos, personalized music, hand holding, art activities, and virtual reality, as well as pharmacologic interventions such as benzodiazepines. However, these techniques have not been well studied for nail surgery.

The Technique

Patients generally are anxious about nail surgery secondary to the pain associated with the local anesthetic infiltration; hence, it is crucial to decrease anxiety during this initial step. In our practice, we provide patients with a palm-sized stress ball made of closed-cell polyurethane foam rubber before surgery. Patients are then instructed to hold the stress ball with the free hand and squeeze it whenever they feel anxious or when they feel any discomfort related to the procedure (Figure). A variety of balls can be bought for less than $1 each, thus making it a cost-effective option.

Practice Implications

Holding a stress ball has been found to reduce both pain and anxiety in patients undergoing conscious surgery.⁴ Furthermore, squeezing a stress ball perioperatively may increase feelings of empowerment, given that patients have direct control over the object, which in turn may have a positive effect on anxiety and patient satisfaction without interfering with the surgical procedure.⁵ Holding a stress ball is a safe, widely accessible, and inexpensive technique that may aid in decreasing patients’ anxiety related to nail surgery. Nonetheless, controlled clinical trials assessing the efficacy of this method in reducing anxiety related to nail surgery are needed to determine its benefit compared to other methods.

A 69-year-old man underwent staged excision for an invasive melanoma (0.4-mm Breslow depth; stage Ia) of the right dorsal nose. Two stages were required to achieve clear margins, leaving a 3.0×2.5-cm defect involving the nasal dorsum, right nasal sidewall, and nasal supratip (Figure 1). He declined any multistage repair and preferred a full-thickness skin graft (FTSG) over any interpolation flap.

Given the size of our patient’s defect, primary repair was not possible and second intention healing may have resulted in a suboptimal cosmetic outcome, potential alar distortion, and prolonged healing. No single local flap, such as the dorsal nasal rotation flap, crescentic advancement flap, bilobed flap, and Rintala flap, would have provided adequate coverage. A FTSG of the entire defect would not have been an ideal tissue match, and given the limited surrounding laxity, a Burow FTSG would have required the linear repair to extend well into the forehead with a questionable cosmetic outcome.

The Technique

We opted to repair the defect using a combination of local flaps for a single-stage repair. Using the right cheek reservoir, a crescentic advancement flap was performed to restore the right nasal sidewall as best as possible with a standing cone taken superiorly. To execute this flap, an incision was made extending from the alar sulcus into the nasolabial fold while preserving the apical triangle of the upper cutaneous lip. The flap was elevated submuscularly on the nose, and broad undermining was performed in the subcutaneous plane of the medial cheek. A crescentic redundancy above the alar sulcus was excised, and periosteal tacking sutures were placed to both help advance the flap and to recreate the nasofacial sulcus.¹

Next, a nasal tip spiral/rotation flap was designed to restore the remaining nasal defect.² An incision was made at the right inferiormost aspect of the defect and extended along the inferior border of the nasal tip as it crossed the midline to the left side of the nose. After incising and elevating the flap in the submuscular plane, there was not enough of a tissue reservoir to cover the entire remaining nasal defect.

To resolve this intraoperative conundrum, simple interrupted sutures were placed into the nasal cartilage at midline to narrow the structure of the nose (Figure 2). Three 4-0 polyglactin 910 sutures were placed beginning with the upper lateral cartilages and extending inferiorly to the lower lateral cartilages. Narrowing the nasal cartilages allowed for a smaller residual defect. The nasal tip rotation flap was then spiraled into place with adequate coverage. Some of the flap tip was trimmed after the superior aspect of the rotation flap was sutured to the inferior edge of the crescentic advancement flap. The immediate postoperative appearance is shown in Figure 3.

Practice Implications

Cartilage sutures highlight an underutilized technique in nasal reconstruction, with few cases reported in the dermatologic surgery literature.^3,4 The interdomal suture is placed through the left and right lower lateral cartilages to help narrow and redefine the nasal tip.⁵ Reported techniques include simple interrupted suture or horizontal mattress suture. Suture material for nasal cartilage may be permanent (nylon or polypropylene) or long-lasting (polydioxanone or polyglactin 910).⁵ The use of interdomal sutures has been reported to narrow and decrease the volume of nasal tip defects prior to repair with local flaps and FTSG.^3,4 In addition to the interdomal suture of the lower lateral nasal cartilage, simple interrupted sutures were placed in the upper lateral cartilages that created an even smaller residual defect. Sutures of the nasal cartilage may be a good option for select patients in dermatologic reconstruction, allowing for a simple repair with the added benefit of improved cosmetic result.

A combination of local flaps may be used to repair large nasal defects involving multiple subunits, especially in patients who decline multistage reconstruction. A nasal tip rotation/spiral flap can be considered for the appropriate nasal tip defect. Suturing the nasal cartilage with either permanent or long-lasting suture can narrow the cartilage and facilitate flap coverage for nasal defects while also improving the appearance of patients with wide prominent lower noses.
