Acquired digital fibrokeratoma (ADFK) is a rare benign fibrous
tissue tumor that occurs over the extremities, predominantly in
the periungual area. We report a case of ADFK over the digit
of the right hand presenting as a finger-like growth; the base of
the lesion showed a collarette of scales. The lesion was excised
with ablative CO2 laser. The histopathology was typical, showing
hyperkeratosis and acanthosis. The core of the lesion had abundant
collagen fibers perpendicular to the long axis of the epithelium.
There was good healing with minimal scarring; the patient was
followed up, and no recurrence was reported more than one
year later. ADFK is a relatively rare tumor, with less than 150
cases reported worldwide; we present a concise review of the
published ADFK cases with their clinical and histopathological
characteristics. To the best of our knowledge, this is the seventh
such case to be reported from India.
