Uterine tumour resembling ovarian sex cord tumour: first report of a large series with follow-up.

While our figure of 23.5% of cases exhibiting malignant behaviour may reflect some bias related to consultation practice our results show that, not uncommonly, these neoplasms have an aggressive clinical course with extrauterine metastasis. Given the overlap in pathological parameters between clinically benign and malignant neoplasms, UTROSCTs are all best regarded as potentially malignant.
