Pachydermodactyly (PDD) is a rare benign form of digital fibromatosis characterized by a progressive painless fusiform swelling of the periarticular soft tissue, surrounding the dorsolateral aspects of the proximal interphalangeal joint. PDD most commonly affects young adolescent males and is frequently unrecognized and misdiagnosed as inflammatory arthritis. In this report, we present a 17-year-old male with a 1-year history of progressive finger swelling in both of his hands diagnosed as PDD. We also highlight PDD's clinical and histologic features with the aim to enhance physician's awareness of this benign condition to cut unnecessary diagnostic tests and interventions.
