Abstract:
Keratoacanthoma is a rapidly growing cutaneous tumor with a histopathologic pattern often suggestive of a squamous cell carcinoma (SCC). It may be viewed as an aborted malignancy which only rarely progresses into an aggressive SCC. It is most likely arising from hair follicle that has the tendency of spontaneous resolution. The diagnosis of keratoacanthoma is based on clinical, histopathologic features and biologic behavior. A 75-year-old woman presented with a 1-month history of a rapidly enlarging exophytic tumor on the lower lip. A biopsy was performed leading to a diagnosis of keratoacanthoma. We report a case of keratoacanthoma on the lower lip, because the mucosal area is an unexpected location.
