Pachydermodactyly: report of two cases.

Pachydermodactyly is a rare and benign form of digital fibromatosis with only a few cases described in the literature. We report two cases of pachydermodactyly affecting young men. In one of them a knuckle pad was found, and the fibromatous thickening of the skin affected not only the finger joints but also the dorsum of the hands. This case can be included in the particular clinical form named pachydermodactyly transgrediens.
