Abstract

Keratoacanthoma (KA) is a cutaneous squamoproliferative tumor with multiple etiologies suggested. KA can have a benign course, resolving spontaneously, but because it can rarely metastasize, some consider it to be a form of squamous cell carcinoma (SCC). We report a 65-year-old Caucasian male diagnosed with KA in the conch of the left ear, which initially resolved with intralesional methotrexate, but eventually recurred.
