Pachydermodactyly - a rare presentation of digital fibromatosis

Pachydermodactyly is a rare acquired form of digital fibromatosis in which patients present with fusiform soft tissue swelling mainly around proximal interphalangeal joints. Etiology of the condition is unclear, but in most of the cases there is an element of repetitive mechanical injury to the skin. Because of its' clinical features, these patients could present to clinicians other than dermatologists such as rheumatologists and orthopedic surgeons. It is essential that the clinician identify this rather benign condition to avoid subjecting their patients to unnecessary and costly investigations. Herein, we report a 17 years old male who presented with soft tissue swelling of proximal interphalangeal joints of both hands over 5 months. He was diagnosed as having pachydermodactyly and treated successfully with intralesional triamcinolone acetonide injections.
