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).
[Mod. L. fr. G. en, in, + chondros, cartilage, + -oma, tumor]

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.

If arising within the medullary cavity, they are known as enchondromas. Chondromas that arise from the surface cortex, deep to the periosteum, are called juxtacortical (or periosteal) chondromas but occur infrequently in this location.
Cartilaginous tumors (such as osteochondromas, enchondromas, and chondrosarcomas) may produce irregularly shaped calcifications within their matrix that resemble popcorn on imaging studies (Figure 16).
