title: [Subungual keratoacanthoma].
abstract: We present a case of subungueal keratoacanthoma. The tumor recurred three months after extirpation and didn't resolve spontaneously. The patient need a new surgery a year later. We revised the literature and comment the clinical and histological features that define this distinct entity and differentiate it from common keratoacanthoma and subungueal squamous cell carcinoma.
