A 58-year-old woman from Mumbai with Fitzpatrick skin type III presents with multiple nodular lesions on the scalp and face that have been present for 2–3 years. She reports that her father had a similar condition and underwent multiple skin surgeries. On examination, she has firm, skin-colored to slightly erythematous nodules scattered over the scalp, forehead, and cheeks. Histopathology of one lesion shows nests of basaloid cells with peripheral palisading and retraction artifact. What is the most appropriate next step in management?
