[Ollier's disease and juvenile ovarian granulosa tumor].

The authors report one case of Ollier's disease in a 12 year-old girl in whom the occurrence of an ascites revealed a secretant juvenile granulosa cell tumor some years later. The tumor was right-sided, homolateral to the hemicorporal side involved by enchondromatosis. Five other cases of this association were previously reported. Attention is drawn not only to the risk of chondrosarcomatous change but also to the possible recurrence of ovarian tumor in the year following ovariectomy.
