Acquired Digital Fibrokeratoma

Excerpt

Acquired digital fibrokeratoma (ADFK) is a relatively rare and benign fibrous tumor. The condition was first reported in 1968 by Bart et al, who noted multiple cases of this uncommon tumor on the fingers. While ADFK typically occurs on the fingers, it can also occur on other acral surfaces, such as the heel, toes, palms, and soles. Therefore, it is often referred to as acral fibrokeratoma.

Clinically, ADFK presents as a small solitary papule surrounded by a characteristic hyperkeratotic collarette. The differential diagnosis usually includes a rudimentary supernumerary digit and the common wart when diagnosing this condition. The treatment of choice is surgical tumor excision, as ADFK does not show spontaneous regression.
