Recurring accessory "fingernail": periungual fibrokeratoma.
A tumor of the fingertip of a 41-year-old woman presented as a diminutive supernumerary digit complete with fingernail. It had recurred five times following previous surgical removal. Histologic study showed it to be a benign fibrokeratoma with a remarkable smooth hyperkeratotic surface producing a simulated nail plate. Complete surgical excision has not been followed by any recurrence within two years.
