수지 운동을 제한하는 단독 골연골종 - 1예 보고 -

The solitary osteochondroma is a hamartoma of the skeleton which derives from an aberrant subperiosteal germ of the fertile cartilage. Osteochondromas, which are uncommon in the hand can occur at the distal end of the proximal and middle phalanx away from the epiphyseal plate region. We experienced a rare case of solitary osteochondroma arising from distal end of fifth proximal phalanx of hand, and limiting the active motion of proximal interphalangeal joint. The patient was treated by marginal excision and tumor showed characteristic microscopic findings of osteochondroma.
