Tinea Capitis Masquerading as Basal Cell Carcinoma.

A 52-year-old white man with alcoholic cirrhosis presented to the Mohs surgery clinic with a 1-month history of tender "bumps" located diffusely on his scalp. Two biopsies performed at an outside institution were read as "basal cell carcinoma" and "actinic keratosis." The patient was scheduled for a large excision of the scalp for presumed multiple nodules of basal cell carcinoma and desired a second opinion from our Mohs surgery clinic.
