Dark facial lesion

Although an elevated and pigmented lesion should be considered for possible melanoma, this one had prominent telangiectasias and was proven to be a basal cell carcinoma (BCC) on biopsy.

While the literature often focuses on light-colored skin types and the high risk of skin cancers, individuals with darker skin can also get melanoma and nonmelanoma skin cancer. Half of the BCCs in African American people are pigmented BCCs, compared to less than 10% for Caucasian individuals. Individuals who are Hispanic have twice the likelihood of pigmented BCCs as those who are Caucasian.¹ Pigmented BCCs manifest as darker lesions, as occurred in this individual. Nonpigmented BCCs tend to be pink or pale in color.

Typically, superficial and very small, nodular BCCs can be successfully treated with 2 cycles of electrodesiccation and curettage. EDC should, however, be avoided in low-risk BCCs when these lesions occur in areas of secondary hair growth, such as the beard or scalp. This is because the epidermis follows the hair follicle, and in sites with deep hair follicles, EDC would have to get down to the subcutis to effectively clear the tumor.

For larger, nodular BCCs, full-thickness excision with adequate margins is warranted. For high-risk types, and those in high-risk areas near the nose, eyes, mouth, and ears, Mohs micrographic surgery is recommended to maximize the likelihood of complete excision while minimizing the loss of normal tissue.

Since the physician suspected this was a pigmented BCC, he performed a superficial shave biopsy on a small representative area of the lesion for diagnosis. This patient’s biopsy confirmed a nodular-type pigmented BCC. The lesion was removed in the office with 5-mm margins oriented along the resting skin tension lines with good closure and cosmetic results.

The patient was advised to have routine skin evaluations every 6 months due to the high risk of additional cancers. He was also advised to take oral niacinamide 500 mg twice daily, which can reduce the risk of actinic keratoses and nonmelanoma skin cancers by 15% and 23%, respectively, in those who have had lesions.²
