Primary chondrosarcoma of the ovary

A case of a large, completely excised left-sided primary ovarian chondrosarcoma occurring in a 61-year-old woman is described. There was no evidence of metastases. Histologically the tumour was a pure chondrosarcoma, which was mainly well differentiated. The patient is well and disease free at 4 years. Review of the literature revealed no other reported cases of pure chondrosarcoma of the ovary. The possible histogenetic origin of this neoplasm is discussed.
