Summarize this article for a 10 year old
Enchondroma is a type of benign bone tumor belonging to the group of cartilage tumors.[1][2] There may be no symptoms,[3] or it may present typically in the short tubular bones of the hands with a swelling, pain or pathological fracture.[4]
Diagnosis is by X-ray, CT scan and sometimes MRI.[4] Most occur as a less than three centimetre size single tumor. When several occur in one long bone or several bones, the syndrome is called enchondromatosis.[4]
Where there are no symptoms, treatment is often not needed.[4] If treatment is required, curettage may be performed.[4] Less than 1% become malignant, unless part of a syndrome.[4]
They comprise around 30% of cartilage tumors.[5] 90% of tumors in the hand are enchondromas.[6]
