chondroblastoma

 [kon″dro-blas-to´mah]
a benign tumor arising from young chondroblasts in the epiphysis of a bone.

chon·dro·blas·to·ma

(kon'drō-blas-tō'mă),
A benign tumor arising in the epiphyses of long bones, consisting of highly cellular tissue resembling fetal cartilage.

chondroblastoma

/chon·dro·blas·to·ma/ (kon″dro-blas-to´mah) a usually benign tumor derived from immature cartilage cells, occurring primarily in the epiphyses of adolescents.

chondroblastoma

[kon′drōblastō′mə] pl. chondroblastomas, chondroblastomata,
a benign tumor, derived from precursors of cartilage cells, that develops most frequently in epiphyses of the femur and humerus, especially in young men. The lesions may contain scattered areas of calcification and necrosis. Also called Codman's tumor.

chondroblastoma

A benign tumour that arises in the epiphysis or in secondary ossification centres of long bones (humerus, proximal and distal femur, proximal tibia) of young adults (< age 30).

Imaging
Well-defined lytic lesion with a fluffy cotton-wool appearance, ± sclerotic border.
