Abstract:
Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis that is characterized by asymptomatic soft tissue swellings on the back and side of the proximal interphalangeal joint areas of the fingers. We report three cases of young male patients who presented with bilateral swelling of the fingers. Histopathologic examination showed epidermal hyperplasia with acanthosis and hyperkeratosis. Collagen fibers in the reticular dermis were thickened and irregularly arranged, and deposition of mucin in the dermis was observed. Since pachydermodactyly usually affects adolescent males with joint swelling, it is often confused with rheumatologic diseases. Here, we report three cases diagnosed with pachydermodactyly based on clinical manifestations and histopathological examination.
