Localized pachydermodactyly in tuberous sclerosis

Abstract

Pachydermodactyly refers to a rare form of digital fibromatosis involving the proximal portions of the fingers. There are only nine cases reported in the literature, all idiopathic and occurring in young men. We report a 5-year-old Chinese boy with tuberous sclerosis who presented with localized pachydermodactyly since birth. This congenital form of pachydermodactyly may represent an additional cutaneous sign of tuberous sclerosis.
