Abstract:
A 28-year-old man of Middle-Eastern descent presented with a raised, pearly, slightly pigmented lesion on the right nasal ala. The lesion had been present for approximately 4 months. An excisional biopsy was taken, and the lesion measured 1.0 cm × 0.9 cm in dimension. The cut surface revealed a firm, white to tan nodule located within the dermis. The patient had no other significant medical history. After the initial excision, the lesion did not recur.
