enchondroma

 [en″kon-dro´mah] (pl. enchondromas, enchondro´mata)
A benign growth of cartilage arising in the metaphysis of a bone. adj., adj enchondro´matous.

en·chon·dro·ma

(en'kon-drō'mă),
A benign cartilaginous growth starting within the medullary cavity of a bone originally formed from cartilage; enchondromas may distend the cortex, especially of small bones, and may be solitary or multiple (endochondromatosis).

enchondroma

[en′kəndrō′mə] pl. enchondromas, enchondromata
Etymology: Gk, en + chondros, cartilage, oma, tumor
a benign, slowly growing tumor of cartilage cells that arises in the extremity of the shaft of tubular bones in the hands or feet. The growth of the neoplasm may distend the bone. Also called enchondrosis, true chondroma.

enchondroma

A benign intramedullary tumour of hyaline cartilage that forms tumours in the medulla of metaphyseal bone and measures up to 5 cm, which accounts for 10% of all benign bone tumours. Half occur in the tubular bones of the hands/feet, especially fingers and toes.

Clinical findings
Most enchondromas of long bones (e.g., femur) are incidental findings in younger patients (age 15–40). Phalangeal enchodromas may predispose to fractures. 

Types
Solitary Enchondroma.
Multiple Enchondromatosis/Ollier disease.
Maffucci syndrome Multiple enchondromas and soft tissue haemangiomas.
