title: Acquired periungual fibrokeratoma with accessory germinal matrix.
abstract: Five cases of acquired periungual fibrokeratoma involving the proximal nail fold were treated surgically. Clinically, all five patients regained normal nail contours postoperatively, but one patient developed a local recurrence 1 year after operation. Histologically, an accessory germinal matrix was observed at the distal end of the lesion in all five cases. Change in pressure around the lesion seemed to have induced the formation of this accessory germinal matrix.
