Pachydermodactyly, mimicker of rheumatoid hands, presents in a patient with Tuberous Sclerosis

Abstract

Pachydermodactyly (PDD) is a rare benign condition characterized by painless soft tissue swelling of small joints of hands. The most common presentation is bilateral Symmetrical swelling of proximal interphalangeal and metacarpophalangeal joint similar to Rheumatoid arthritis. The etiology of this disease is unknown, and it sometimes can coexist with other diseases. We present here a case of PDD coexisting with Tuberous Sclerosis, an autosomal dominant genetic disorder characterized by of formation of multiple benign multisystem tumors.
