Growing brown and pink plaque

A shave biopsy of the lesion confirmed a nodular and pigmented basal cell carcinoma (BCC). In the United States, BCC is the most common cancer and accounts for 80% of all skin cancer diagnoses. BCC is also the most widespread cancer in White, Hispanic, and Asian patients and the second most common skin cancer in Black patients.

In all patients, BCC presents as a shiny growing macule, papule, or plaque, usually in areas of sun exposure. Much less is known about the role of UV exposure in skin of color because of the lack of high-quality studies in this population. Despite this, BCC in skin of color most often presents on the head and neck, as it does in non-Hispanic White patients. There is a correlation between lighter skin tones in Black patients and increased numbers of BCC diagnoses.

When assessing a suspicious skin lesion in skin of color, be on the lookout for the following visual cues. Pigmentation, clinically and on dermoscopy, is a more common feature of BCCs in non-White patients—occurring in more than half of all BCCs in skin of color.¹ While pigmentation in a skin tumor may be mistaken for melanoma, the blue ovoid nests, brown dots in focus, and brown leaf-like areas on dermoscopy are BCC-specific clues that can alert the clinician to the diagnosis. In all patients, telangiectasias are another hallmark of BCC but may be the only feature in White patients and just one of many features in non-White patients.

In small data sets, there is no difference in tumor-related morbidity and prognosis between White and Black patients with BCC. Additionally, BCCs in White, Asian, and Hispanic patients have had no differences in preoperative tumor size, number of Mohs stages, and outcome.¹

In this case, the patient underwent a complete excision with a 5-mm margin. She remained free of new or recurrent BCCs over the next 2 years, with surveillance exams twice a year.
