A 55-year-old male presented with a painless, progressively enlarging, horn-like projection over the lateral aspect of the right index finger for one year. On examination, the lesion was a solitary, pedunculated, exophytic growth measuring approxi mately 1.5 cm in length with a broad base of about 1 cm, arising from the lateral surface of the digit. A characteristic hyperkera totic collarette was noted at the base, and the lesion had a firm consistency without tenderness or signs of inflammation. There was no history of preceding trauma or chronic irritation. Clini cal differentials included cutaneous horn, verruca, and super numerary digit. The lesion was excised under local anaesthesia with a narrow margin, and the wound was closed primarily.

Histopathological examination revealed a finger-like pro jection with marked hyperkeratosis and acanthosis of the epi dermis, along with a core of densely packed collagen bundles arranged vertically in the dermis, consistent with digital fibro keratoma. The absence of adnexal structures, cartilage, or neu ral elements excluded a supernumerary digit. Based on the le sion size and histomorphological features, a diagnosis of giant acquired digital fibrokeratoma was established. The postopera t ive period was uneventful, with complete healing by primary intention and no recurrence at three-month follow-up.

Acquired digital fibrokeratoma is a rare benign fibrous tumor of the digit that typically presents as a solitary, slow-growing lesion. The presence of a hyperkeratotic collarette and a central f ibrous core are characteristic histopathology features aiding clinical diagnosis. Complete surgical excision is curative, with recurrence being rare when the lesion is entirely removed.
