24-year-old female presents with a 3-month history of nonpruritic rash
, typically characterized by symmetrical, nonblanching, purpuric, telangiectatic, and atrophic patches with a predilection for the lower extremities and buttocks.
Plaques are usually 1-3 cm in diameter and annular with punctate telangiectasias and cayenne pepper petechiae in the border. The annular patches may form concentric rings. It is most commonly seen in children and young females.
The etiology of Majocchi’s disease is largely unknown and idiopathic.
Triggers are not always detected but may be associated with viral infections, chronic comorbidities, and medications. Levofloxacin and isotretinoin have been described in as reports as causing PATM. Other medications reported to cause PPD include sedatives, stimulants, antibiotics, NSAIDS, and cardiovascular drugs.
Diagnosis of PATM is clinical and histopathologic. Direct immunofluorescence (DIF) may show fibrinogen, IgM, and/or C3 deposition in superficial dermal vessels. Histopathologic findings show lymphocytic infiltrate involving the superficial small vessels, extravasated red blood cells, and hemosiderin-laden macrophages.
There is no consensus regarding treatment with variable responses to proposed treatment based on reports and case studies. The first line of treatment is topical corticosteroids and compression hose. Additional treatments, including narrowband UVB phototherapy (NBUVB), griseofulvin, pentoxifylline, cyclosporine, colchicine, rutoside with ascorbic acid, and methotrexate, have been used with varying success.
In this patient, a punch biopsy was performed, which revealed lymphocytes and extravasated erythrocytes and siderophages in the dermis. She was treated with topical steroids with improvement. She started NBUVB, a short course of griseofulvin, and vitamin C supplements.
This case and the photos were photo submitted by Ms. Xu, of the University of California, San Diego, and Dr. Sateesh, of San Diego Family Dermatology. Dr. Donna Bilu Martin edited the column.

A 31-year-old female presented with a burning rash on upper arms, groin, and axillae
The exact cause is unknown, but possible causes include medications, dental amalgam fillings, or an autoimmune reaction. Drugs implicated in causing LP include beta-blockers, methyldopa, penicillamine, quinidine, and quinine. A meta-analysis of case-control studies show a statistically significant association between hepatitis C infection and LP patients; thus, all patients presenting with LP should be screened for hepatitis.1 Individuals of all age groups and races can be affected by LP, but it is predominantly observed in middle-aged adults. Women are also twice as likely to get oral lichen planus.2
Atrophic lichen planus, the least common form of LP, presents as flat, violaceous papules with an atrophic, pale center. Although these papules can be found anywhere on the body, they most commonly affect the trunk and/or legs on areas of the skin previously affected by classical lichen planus.3 In most cases, LP is diagnosed by observing its clinical features. A biopsy is recommended to confirm the diagnosis for more atypical cases.
Histopathology reveals thinning of the epidermis with flattening of the rete ridges, vacuolar degeneration of the basal layer, and a lichenoid mononuclear infiltrate in the papillary dermis.
If the patient is diagnosed with LP but experiences no symptoms, treatment is not needed as LP may resolve spontaneously within 1-2 years. Recurrences are common, however. Lesions may heal with hyperpigmentation. Possible treatments that can help relieve symptoms of pruritus are high potency topical corticosteroids, calcineurin inhibitors, and antihistamines. In more severe and widespread cases, lesions may respond well to systemic corticosteroids or intralesional steroid injections.4 Phototherapy is reported to be effective as well. Acitretin, isotretinoin, methotrexate, hydroxychloroquine, and mycophenolate mofetil are all described in the literature. It is important to note that LP on mucous membranes may be more persistent and resistant to treatment.1
In this patient, a punch biopsy was performed, confirming the diagnosis. The patient was treated with topical and intralesional steroids, as well as a course of prednisone, and her lesions improved with treatment. Hepatitis serologies were negative.
This case and photo were submitted by Ms. Erras of the University of California, San Diego, and Dr. Sateesh, of San Diego Family Dermatology, and edited by Donna Bilu Martin, MD.

A 34-year-old male presented with 10 days of a pruritic rash
Less frequently observable infectious agents associated with EM are Mycoplasma pneumoniae, Histoplasma capsulatum, and parapoxvirus (orf). Rarely, EM is triggered by drug eruption or systemic disease. Individuals of all age groups and races can be affected by EM. However, it is predominantly observed in young adult patients (20-40 years of age), and there is a male predominance.
Patients typically present with the abrupt onset of symmetrical red papules that evolve into typical and atypical targetoid lesions. Lesions evolve in 48-72 hours, favoring acrofacial sites that then spread down towards the trunk. Systemic symptoms such as fever and arthralgia may accompany the skin lesions.1-3
Erythema multiforme is recognized in two forms: EM minor and EM major. Both forms share the same characteristic of target lesions. However, the presence of mucosal involvement distinguishes the two. Mucosal involvement is absent or mild in EM minor, while mucosal involvement in EM major is often severe.2,3 Painful bullous lesions are commonly present in the mouth, genital, and ocular mucous membranes. Severe symptoms can often result in difficulty eating and drinking.
Diagnosis is largely clinical. Further histologic study may accompany diagnoses to exclude differential diagnosis. In EM, direct immunofluorescence (DIF) is negative. Histopathology reveals apoptosis of individual keratinocytes.1,2
Therapeutic treatment for painful bullous lesions in the mouth involve antiseptic rinses and anesthetic solutions. Preventive treatment for patients with HSV-associated EM recurrence includes oral acyclovir or valacyclovir.2
In this patient, a punch biopsy was performed, confirming the diagnosis. A DIF was negative, and a chest x-ray was negative. Treatment was initiated with oral acyclovir, doxycycline, and a prednisone taper. In addition, topical clobetasol propionate and magic mouthwash (Maalox/lidocaine/nystatin) was prescribed. The patient was placed on daily suppressive valacyclovir to prevent frequent recurrence of EM.

75-year-old White male presenting with progressive pruritus and a worsening rash
, although it can also be contracted through contaminated bedding and clothing. It can affect all races and ages.
Patients typically present with extremely pruritic, symmetric papules and excoriations. In nodular scabies, nodules and large papules are seen on exam. Thin lines in the skin called burrows may be present, especially in the webs between fingers. Female mites create burrows as they tunnel through the epidermis and lay eggs. The wrists, areola, waistline, and groin may all be involved, creating an imaginary circle between the areas described as the “circle of Hebra.” Penile and scrotal lesions are common in men.
Patients usually experience worse pruritus at night, which disturbs sleep. Crusted scabies is a severe form of scabies more often seen in those with immunocompromised immune systems. Clinically, thick crusted and scaly patches are present that are teeming with mites.
Diagnosis can be confirmed by performing a scabies prep, during which a burrow is scraped with a surgical blade. A drop of mineral oil is placed on the skin cells. The mite, ova, and feces can be visualized under the microscope. Wrists and hands usually have the highest yield for finding the parasites.
Topical treatments include permethrin 5% cream, lindane, benzyl benzoate, and crotamiton, and should be applied as two treatments a week apart. In the United States, permethrin is most commonly used. Ivermectin pills are used off label and are very effective and may be repeated for 1-2 weeks. All household contacts should be treated. Patients may still have pruritus for 2-4 weeks following treatment.
In this patient, a scabies prep was performed prior to performing repeat skin biopsies. Microscopic examination revealed ova, one mite, and feces. Treatment was initiated with ivermectin and permethrin.
Photos and case were submitted by Susannah Berke, MD, and Damon McClain, MD, Three Rivers Dermatology, Coraopolis, Pa.; and Dr. Bilu Martin.

A 22-year-old presented with erythematous papules on her fingers and toes
than men. Clinically, distal extremities such as toes, fingertips and heels, as well as the rims of the ears or nose develop erythematous to purple plaques. Lesions may be painful or pruritic. Over time, lesions may develop atrophy and resemble those of discoid lupus. While the pathogenesis is unknown, exposure to cold or wet environments can precipitate lesions.
Histopathology reveals a deep and superficial lymphocytic infiltrate with perieccrine involvement and fibrin deposition in vessels. Dermal edema is often present. Direct immunofluorescence shows an interface dermatitis positive for IgM, IgA, and C3.
The Mayo Clinic developed diagnostic criteria for diagnosing chilblains lupus. Two major criteria are acral skin lesions induced by cold exposure and evidence of lupus erythematosus in skin lesions (histopathologically or by direct immunofluorescence). Three minor criteria are the coexistence of systemic lupus erythematosus or discoid lupus erythematosus, response to antilupus treatment, and negative cryoglobulin and cold agglutinin studies.
Chilblains, or perniosis, has a similar clinical presentation to chilblain lupus erythematosus. However, serologic evidence of lupus, such as a positive antinuclear antibody (ANA), will be absent. Lupus pernio (Besnier-Tenneson syndrome) is a form of sarcoidosis that tends to favor the nose. These lesions are not precipitated by cold. It can be differentiated on histology. “COVID toes” is an entity described during the coronavirus pandemic, during which dermatologists noted pernio-like lesions in patients testing positive for coronavirus.
The patient’s labs revealed a positive ANA at 1:320 in a nucleolar speckled pattern, elevated double-stranded DNA, low C3 and C4 levels, elevated cardiolipin IgM Ab, and elevated sedimentation rate. COVID-19 antigen testing and COVID-19 antibodies were negative. A serum protein electrophoresis was negative. Cryoglobulins were negative.
Treatment includes protection from cold. Smoking cessation should be discussed. Topical steroids and topical calcineurin inhibitors are first-line treatments for mild disease. Antimalarials, such as hydroxychloroquine can be helpful. Systemic calcium channel blockers, systemic steroids, mycophenolate mofetil, and tacrolimus have all been reported as treatments. This patient responded well to hydroxychloroquine and topical steroids with full resolution of lesions.

Over time, lesions may develop atrophy and resemble those of discoid lupus. While the pathogenesis is unknown, exposure to cold or wet environments can precipitate lesions.
Histopathology reveals a deep and superficial lymphocytic infiltrate with perieccrine involvement and fibrin deposition in vessels. Dermal edema is often present. Direct immunofluorescence shows an interface dermatitis positive for IgM, IgA, and C3.

A 73-year-old White male presented with 2 days of a very pruritic rash
Reactions can occur anytime from within the first 2 weeks of treatment up to 10 days after the treatment has been discontinued. If a drug is rechallenged, eruptions may occur sooner. Pruritus is commonly seen. Clinically, erythematous papules and macules present symmetrically on the trunk and upper extremities and then become more generalized. A low-grade fever may be present.
Antibiotics are the most common causes of exanthematous drug eruptions. Penicillins and trimethoprim-sulfamethoxazole are common offenders. Cephalosporins, anticonvulsants, and allopurinol may also induce a reaction. As this condition is diagnosed clinically, skin biopsy is often not necessary. Histology is nonspecific and shows a mild perivascular lymphocytic infiltrate and few epidermal necrotic keratinocytes.
In drug reaction with eosinophilia and systemic symptoms (DRESS), symptoms present 2-6 weeks after the offending medication has been started. The cutaneous rash appears similar to an exanthematous drug eruption; however, lesions will also present on the face, and facial edema may occur. Fever is often present. Laboratory findings include a marked peripheral blood hypereosinophilia. Elevated liver function tests may be seen. Viruses such as Epstein-Barr virus, enteroviruses, adenovirus, early HIV, human herpesvirus 6, and parvovirus B19 have a similar clinical appearance to an exanthematous drug eruption. A mild eosinophilia, as seen in a drug eruption, helps to distinguish between a drug eruption and viral exanthem. In Stevens-Johnson Syndrome, mucosal membranes are involved and skin is often painful or appears dusky.
Treatment of exanthematous drug eruptions is largely supportive. Discontinuing the drug will help speed resolution and topical steroids may alleviate pruritus.

A 70-year-old man presents with firm papules on his hand and fingers
, although women are more often affected than men. GA most commonly appears in the first 3 decades of life. Although the etiology is not known, GA may represent a delayed hypersensitivity reaction. A link between GA and diabetes mellitus, autoimmune thyroiditis, dyslipidemia, and rarely, malignancy may exist.
GA is most commonly localized, presenting as an asymptomatic, erythematous, annular plaque with a firm border and central clearing localized to the wrists, ankles, and dorsal hands or feet. This form is the type most often seen in children. Generalized GA is far less common and presents later in life as multiple asymptomatic or pruritic papules and plaques on the trunk and extremities. Less common variants include subcutaneous GA, patch GA, atypical GA, and perforating GA. Perforating GA occurs on the dorsal hands and presents as (umbilicated) papules, and seems consistent with this patient’s clinical presentation. Histologically, transepidermal elimination of collagen is typically seen in perforating GA.1
Histology in this patient’s biopsy revealed a granulomatous dermatitis consistent with granuloma annulare. A palisaded arrangement of histiocytic cells surrounding altered collagen with increased dermal mucin was seen. There was associated perivascular mononuclear inflammatory infiltrates. The overlying epidermis was unremarkable.
Granuloma annulare often spontaneously resolves without sequelae. In some cases, atrophy may result. Lesions may also recur. Localized GA is often treated with high-potency topical corticosteroids or intralesional corticosteroids. For generalized GA, topical or intralesional corticosteroids may be used for select lesions. Topical calcineurin inhibitors, light therapy, cryotherapy, imiquimod, hydroxychloroquine, isotretinoin, and dapsone have also been reported in the literature as possible treatments.

An 80-year-old female developed a painful purulent nodule a day after gardening
. There are more than 100 species of dematiaceous fungi that can cause phaeohyphomycosis, including Alternaria, Exophiala, Phialophora, Wangiella, Bipolaris, Curvularia, and Exserohilum.1,2 The causative fungi are found in plants and soil, so they are commonly seen after activities such as gardening or walking barefoot. Trauma, such as a splinter, typically incites the infection. Infections can present with superficial, cutaneous and subcutaneous involvement.
Sporotrichosis, also called Rose gardener’s disease, is a mycosis caused by Sporothrix schenckii. A typical presentation is when a gardener gets pricked by a rose thorn. Classically, a pustule will develop at the site of inoculation, with additional lesions forming along the path of lymphatic drainage (called a “sporotrichoid” pattern) weeks later. Atypical mycobacterial infections, mainly Mycobacterium marinum, may also present in this way. Histopathology and tissue cultures help to differentiate the two.
An incision and drainage with pathology was performed in the office. Upon opening the nodule, a large wood splinter was extracted. Both the foreign body and a punch biopsy of skin were sent in for examination. Pathology revealed polarizable foreign material in association with suppurative inflammation and dematiaceous fungi. PAS (Periodic-acid Schiff) and GMS (Grocott methenamine silver) stain highlighted fungal forms. Cultures were negative.
Local disease may be treated with excision alone. Oral antifungals, such as itraconazole, fluconazole, or ketoconazole may be used, although may require long treatment courses for months. Amphotericin B and flucytosine may be required in systemic cases. Almost all cases of disseminated disease occur in immunocompromised patients. Our patient’s hand resolved after removal of the causative thorn.

A 35-year-old with erythematous, dusky patches on both lower extremities
Zinc deficiency may be inherited or acquired. Acrodermatitis enteropathica is an autosomal recessive genetic disorder caused by a mutation in the gene that encodes a zinc transporter. It presents in infancy with the classic triad of diarrhea, dermatitis, and alopecia. Acquired zinc deficiency is due to causes such as alcoholism, malabsorption disorders like cystic fibrosis, inflammatory disease, gastrointestinal surgery, metabolic stress following general surgery, eating disorders, infections, malignancy, or occasionally in pregnancy. Classically, the face, groin, and extremities are affected (often acral), with erythematous, scaly patches. Pustules and bullae may be present. Angular cheilitis is often seen.
Necrolytic migratory erythema, or glucagonoma syndrome, is a very rare syndrome that presents as annular, erythematous patches with blisters that erode on the lower extremities and groin. The condition results from a cancerous tumor in the alpha cells of the pancreas called a glucagonoma, which secretes the hormone glucagon. It is often associated with diabetes and hyperglycemia.
Necrolytic acral erythema resembles acrodermatitis enteropathica and necrolytic migratory erythema clinically, however, it is associated with hepatitis C infection. Lesions are plaques with well defined borders distributed acrally. Treatment of the hepatitis C often improves the dermatitis.
Our patient’s blood work was consistent with nutritional deficiency and revealed low levels of zinc, vitamin A, ceruloplasmin, albumin and prealbumin, total protein, calcium, selenium, vitamin E, vitamin K, and vitamin C. Her hemoglobin A1C was under 4. Her hepatitis serologies were negative. The patient received total parenteral nutrition with subsequent complete resolution of her rash. Follow up for gastric bypass patients should be performed long term as they are at risk for nutritional deficiencies.

Classically, the face, groin, and extremities are affected (often acral), with erythematous, scaly patches. Pustules and bullae may be present. Angular cheilitis is often seen.
Necrolytic migratory erythema, or glucagonoma syndrome, is a very rare syndrome that presents as annular, erythematous patches with blisters that erode on the lower extremities and groin. The condition results from a cancerous tumor in the alpha cells of the pancreas called a glucagonoma, which secretes the hormone glucagon. It is often associated with diabetes and hyperglycemia.
Necrolytic acral erythema resembles acrodermatitis enteropathica and necrolytic migratory erythema clinically, however, it is associated with hepatitis C infection. Lesions are plaques with well defined borders distributed acrally. Treatment of the hepatitis C often improves the dermatitis.
Our patient’s blood work was consistent with nutritional deficiency and revealed low levels of zinc, vitamin A, ceruloplasmin, albumin and prealbumin, total protein, calcium, selenium, vitamin E, vitamin K, and vitamin C. Her hemoglobin A1C was under 4. Her hepatitis serologies were negative. The patient received total parenteral nutrition with subsequent complete resolution of her rash. Follow up for gastric bypass patients should be performed long term as they are at risk for nutritional deficiencies.

Trypanosomatidae
Leishmaniasis is caused by protozoa of the family Trypanosomatidae, called Leishmania. The vector is a sandfly infected with the protozoa.1
The three main forms of leishmaniasis – cutaneous, mucocutaneous, or visceral – varies with the species of organism involved, the geographic distribution, and the immune response of the patient. A majority of the cases seen in the United States are from patients who contracted the disease elsewhere, particularly from Peru and Brazil.2
Lesions can vary from asymptomatic to severe. The initial lesion typically develops within weeks or months, and presents as an erythematous papule that is seen at the bite site.3 The papule evolves into a nodule or plaque that may ulcerate and crust.3 The ulcer can be distinguished by a raised and distinct border. In older stages, atrophic scarring may be seen. In some cases, the lesions may present years after exposure, because of immunosuppression or trauma.
Histology of CL reveals tuberculoid granulomas with parasitized histiocytes present. Amastigotes with distinct nuclei and kinetoplasts characterize Leishmania.2 In addition to histology, the biopsy may be sent for the press-imprint-smear method (PIS). In a study of 75 patients, the PIS method showed a higher sensitivity, as well as being a less costly and more rapid option for diagnosis.5
The treatment depends on the severity of the lesion and the species of the Leishmania genus. Mild lesions may resolve spontaneously. Topical imiquimod, cryotherapy, photodynamic therapy, and heat therapy may aid in the healing process.5 Systemic azole antifungal medications, miltefosine, and amphotericin B, and pentamidine may be used for more persistent lesions. In very severe cases, pentavalent antimonials (sodium stibogluconate, Pentostam) may be administered intravenously, although there is a high occurrence of recorded side effects.2
