Definition
Meaning

A type of non-cancerous bone lesion that develops from cartilage cells and grows within the interior of a bone, most commonly in the small bones of the hands and feet. It is often an incidental finding on X-rays.
Linguistics
Semantic Notes
This term is strictly medical and pathological. It denotes a specific type of tumor, distinguished from its malignant counterpart, chondrosarcoma. The prefix 'en-' signifies 'within' (Greek).

Examples
By Part of Speech
adjective
British English
- The enchondromatous lesion was monitored for several years.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'хондрома' (chondroma) which can be more general. The Russian equivalent is 'энхондрома' (same spelling).
- Avoid literal translations like 'внутрихрящевая опухоль' in favour of the established loan term 'энхондрома' in medical contexts.
Common Mistakes
- Misspelling as 'enchondria' (confusion with mitochondria) or 'enchondrosis'.
- Mispronunciation by placing stress incorrectly (e.g., EN-chon-droma). Correct stress is on 'dro'.
- Using it as a general term for any benign bone tumour.

FAQ
Frequently Asked Questions
No, it is a benign (non-cancerous) tumour. However, in very rare cases, it can transform into a malignant chondrosarcoma.
Most asymptomatic enchondromas require no treatment and are simply monitored. If they cause pain, fracture, or show signs of growth, treatment may involve curettage (scraping out) and bone grafting.
Yes. The presence of multiple enchondromas is a condition called enchondromatosis (e.g., Ollier disease or Maffucci syndrome), which carries a higher risk of malignant transformation.
It is often first identified incidentally on an X-ray (showing a well-defined, lytic lesion with possible internal calcifications). A definitive diagnosis, if needed, is made via biopsy and histopathological examination.
