Dermoscopic findings in a case of multiple subungual fibromas

Abstract

Periungual and subungual fibromas, also known as Koenen tumors, are diagnostic findings of tuberous sclerosis. The clinical ap-pearance and histological features that characterize ungual fibromas are well defined. However, dermoscopic findings of these benign tumors have not been reported previously. Here we report a rare presentation of multiple subungual fibromas of all fingers in a developmentally delayed patient with tuberous sclerosis along with the dermoscopic features of the ungual tumors.
