Keratoacanthoma (KA) is a cutaneous squamoproliferative tumor with multiple possible etiologies While. KA commonly have a benign course and resolve spontaneously. However, because there are rarely instances where it can metastasize, some consider it to be a form of squamous cell carcinoma (SCC). We report the case of a 65-year-old Caucasian man diagnosed with KA in the conch of the left ear, which initially resolved with intralesional methotrexate but eventually recurred.
