Two Cases of Acquired Fibrokeratoma Occuring on the Prepatellar Area and the Nail Bed / 대한피부과학회지

ABSTRACT

Aquired fibrokeratoma is a rare, benign tumor which occurs most frequently on the fingers. Because of the digital predilection, a term of digital fibrokeratoma has been frequently used. We present here two cases of acquired fibrokeratoma occurring on the prepatellar area and the proximal nail bed which are unusual sites of this lesion. A skin-colored, hyperkeratotic tumor with finger-like projection was found on the prepatellar area of a 29-year-old man and a round pedunculated nodule was found on the proximal nail bed of second finger of a 74-year-old woman. Histopathologic examination revealed typical features of acquired fibrokeratoma.
