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

[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.

Image-guided transnasal biopsy of the mass was performed and sent to the Armed Forces Institute of Pathology, where the lesion was identified as an enchondroma with atypical features that were suspicious for early malignant transformation, possibly a low-grade chondrosarcoma.
An enchondroma is an intraosseous, usually benign tumor that develops in proximity to growth-plate cartilage.
Imagawa et al reported an enchondroma in the left middle cranial fossa of a patient with generalized enchondromatosis.
2) Considered a subtype of enchondromatosis, Maffucci syndrome presents with multiple enchondromas that are associated with soft tissue hemangiomas.

Background: Enchondromas are usually solitary benign lesions, consisting of ectopic hyaline cartilage deposits in intramedullary bone.
Some lesions, such as solitary bone cysts (Figure 4), enchondromas (Figure 5), EG and Ewing's sarcoma, tend to be centrally located.
Several lesions that can be polyostotic include multiple hereditary exostoses, enchondromas, fibrous dysplasia and, occasionally, eosinophilic granulomas.
Enchondromas are hyaline cartilage tumors in the medullary canal.
A similar rare condition, Maffucci's syndrome, is manifested by enchondromas and soft tissue vascular lesions.
Maffucci's syndrome is associated with a higher frequency of malignant transformation of the enchondromas than is Ollier's disease.
Radiopharmaceutical uptake can vary greatly depending upon local reactive bone formation, ossification of the enchondromas, and local hyperemia.
