Abstract

Keratoacanthoma is the epidermal tumor characterized by the benign course such as rapid growth and spontaneous resolution. Rarely keratoacanthoma invades adjacent structures. Therefore, controversies have arisen about the biologic behavior whether keratoacanthoma is a benign tumor or a variant of low grade cutaneous squamous cell carcinoma. We report a case of the recurred keratoacanthoma at the nasal vestibule treated with the surgical excision and the reconstruction by local bilobed rotation flap in a 54-year old female whose final pathology was confirmed as well differentiated squamous cell carcinoma.
