ABSTRACT

We report a 42-year-old man who presented with a recurrent painful nodule on the proximal nail fold of the left fifth finger. The tumour had been surgically excised at another department a month earlier, and histological examination had shown a keratoacanthoma. The patient underwent Mohs micrographic surgery, and no recurrence was evident 16 months later. Mohs micrographic surgery appears to be an effective option in the management of this unusual variant of keratoacanthoma, which is often difficult to eradicate.
