Keratoacanthoma (KA) is a common and distinctive cutaneous neoplasm that behaves in a benign fashion, displaying rapid growth followed by spontaneous involution. Clinical and histological examinations are essential to confirm this diagnosis, although differentiating KA from squamous cell carcinoma is often difficult. In general, complete surgical excision is a standard of care for solitary KAs; however, the conservative approach could be considered in some selected situations.We present the case of a 59-year-old female patient who presented with a KA, on a high-risk area, displaying self-involution after undergoing a biopsy. This is one of the few cases in the literature in which spontaneous resolution process was photographically documented with good cosmetic results.
