Chondroma
Definition:
(n.) A cartilaginous tumor or growth.
Example Sentences:

Enchondroma
Definition:
(n.) A cartilaginous tumor growing from the interior of a bone.
Example Sentences:
(1) Maffucci's syndrome is a rare, congenital disease of unknown cause characterized by the development of multiple enchondromas and soft-tissue hemangiomas.

(3) Enchondroma is a commonly encountered bone tumor in the foot, frequently necessitating excision.
(4) A morphometric study was performed on 600 nuclei from 6 benign chondroid tumours (BCL) (3 enchondromas and 3 exostoses), 600 nuclei from 6 well-differentiated chondrosarcomas (WDC) and 200 nuclei from moderately-differentiated chondrosarcomas (MDC) obtained by fine needle aspiration biopsy.
(5) A case is reported in which an epithelioid sarcoma developed in an apparently benign enchondroma or bone infarct at the site of a chrome-cobalt total knee replacement.
(6) Maffucci's syndrome consists of multiple cutaneous hemangiomas, dyschondroplasia, and often enchondroma.
(7) In the region of the calcar femorale, crossing trabeculae, similar to the appearance of an enchondroma or bone infarct, have been described in osteoporosis and osteoarthritis and probably represent unmasking of normally present reinforcing trabeculae.
(8) Five patients had multiple enchondromas (Ollier's syndrome), five children had congenital hand deformities, and all of these had previously had bone grafts harvested for associated craniofacial reconstructions.
