(os'tē-ō-kon-drō'mă),
A benign cartilaginous neoplasm that consists of a pedicle of normal bone (protruding from the cortex) covered with a rim of proliferating cartilage cells; may originate from any bone that is preformed in cartilage, but is most frequent near the ends of long bones, usually in patients 10-25 years of age; the lesion is frequently not noticed, unless it is traumatized or of large size; multiple osteochondromas are inherited and referred to as hereditary multiple exostoses.

osteochondroma

A bony protrusion capped with cartilage, occurring most commonly at the ends of long bones. These are thought to be disorders of bone growth rather than tumours, but occasionally malignant change supervenes.

osteocartilaginous exostosis

; osteochondroma; subungual exostosis benign, neoplastic pedicle of cartilage-capped bone, arising at the dorsal aspect or tip of a terminal phalanx in response to trauma; causes local pain and distortion of overlying nail plate; treated by surgical excision, after removal of the overlying nail plate; patients should be warned of 30% risk of onychocryptosis subsequent to nail plate regrowth

osteochondroma

a benign bone tumor consisting of projecting adult bone capped by cartilage which is proliferating and undergoing endochondral ossification; cartilaginous exostosis.
