title: Pachydermodactyly: A Case Report Including Histopathology.
abstract: Pachydermodactyly (PDD) is a rare form of digital fibromatosis characterized by painless soft tissue swelling, primarily about the proximal interphalangeal joints. The skin at the metacarpophalangeal joints, the palm, and the dorsum of the hand may also be involved. Because swelling can occur over the proximal interphalangeal and metacarpophalangeal joints, PDD may be confused with juvenile inflammatory arthropathy and may even occur concurrently. We present the clinical and histopathologic findings of a case of PDD characterized by bilateral proximal phalangeal involvement of the index through little fingers.
