[Young male with pachydermodactyly: imaging findings].

Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis characterized by an asymptomatic soft-tissue swelling affecting the skin of the lateral spects of the proximal interphalangeal joints of the fingers, and sometimes can be misdiagnosed with some rheumatic conditions. Magnetic resonance images changes have not been described in any of the case reports in the literature. We report here a case of PDD in a 19-year-old male and we describe its findings on X-ray and magnetic resonance images. We briefly discuss PDD.
