ACQUIRED DIGITAL FIBROKERATOMA
By Gary M. White, MD
The acquired digital fibrokeratoma (ADFK) is a benign fibrous growth that usually occurs on the finger and thus may cause persistent functional limitation.
A flesh-colored papule or nodule with an epidermal collarette on the proximal portion of the index finger is most characteristic. Lesions may also occur on other fingers or even the heel. The main differential is a wart which, in contrast to the ADFK, gives rise to multiple lesions and has black dots.
No treatment is needed. Cryotherapy is not effective. Shave biopsy may be done.
