Acquired digital fibrokeratoma



Acquired digital fibrokeratoma

Acquired digital fibrokeratoma is of no clinical significance and arises most often in adult life, affecting males more often than females. It presents as a slowly growing firm nodule or excrescence, usually less than 1 cm in size, on the fingers or toes; as such, it may clinically resemble a supernumerary digit. A similar lesion has been documented on the heel. Some regard these lesions as traumatic, although with little supporting evidence. acquired digital fibrokeratoma may be similar to the periungual fibroma that occurs in tuberous sclerosis but the latter tends to be multiple and has minimal or no epidermal component.
