[Benign synovialoma of knee in children (author's transl)]

The authors report 2 cases of benign synovialoma of knee in children. After studying the clinical and radiological symptomatology, they insist on the anatomical pathological criteria which are the only specific ones. However, this benign affection takes on a serious complexion, in the diffuse forms, on account of the incomplete and impairing nature of an exclusively surgical treatment.
