Epiphyseal chondroblastomata ate tumors of bone, occurring in the adolescent or early adult age group, involving the epiphyses of bones.
The origin of this tumor is considered to be a reticulohistiocytic cell which differentiates into chondroblasts and then into cartilage. In the eight cases of this tumor reported, conservative therapy was curative in all cases treated.
If the lesion has penetrated the epiphysis and injured the joint cartilage, we consider it should be excised and followed by bone grafts in order to make up for loss of substance and maintain the continuity of the limb.
When a surgical approach is impossible, roentgen therapy may succeed in curing the lesion.
