title: [Benign chondroblastomas of bone. Anatomo-clinical and ultrastructural study apropos of 11 cases].
abstract: The authors have observed 9 cases of benign chondroblastoma of bones. After a review of the literature they recall that this is a rare condition (1% of bone tumors). That it is twice more frequent in males than in females. Aged 10-20, at the level of growing epiphysis shoulder and knee are the more common sites. The X-rays pictures are described, as well as the pathological findings. Pathological features close to those noted in aneurismal bone cysts were often encountered. The ultra-structure of these tumours was also studied. This type of tumour is essentially benign, however the association of aneurism-like pictures increase the incidence of recurrences.
