Osteochondroma of the pisiform: A case report

The current report describes a child with a wrist swelling which on evaluation was found to be an osteochondroma of the pisiform, which is seldom described in the literature, and managed by excision biopsy. Though osteochondromas of the carpal bones are rare they should be included in the differential of any wrist swelling with the symptom complex varying from pressure effects to surrounding soft tissues and nerves, attritional tendon ruptures, carpal instabilities and arthritis.
