Pachydermodactyly.

A 16-year-old boy presented to the Pediatric Dermatology Clinic at the Charles C. Harris Skin and Cancer Pavilion with a two-year history of asymptomatic swelling of fingers on both hands. His condition had remained undiagnosed after previous evaluation by several dermatologists and hand specialists. He initially had noticed increased fullness of his proximal left fourth digit. Several months later, he noted swelling of his left fifth digit and right second through fourth digits. The patient reported no pain, pruritus, restriction of movement, morning stiffness, or trauma. He also denied repetitive hand-rubbing movements although his mother stated that he had this habit as a child. Past medical history included allergic rhinitis and asthma. Similar hand findings were not present in any other members of his family.
