Management of non-epithelial ovarian tumours

Ovarian tumours of non-epithelial origin are less common than those of epit helial origin but must be distinguished from these as their natural history and management differ. As these tumours are rare, histological review by a n expert in the field is essential. There have been no randomised trials to outline the management of these tumours and therefore this paper represent s a review of descriptive data. Non-epithelial ovarian tumours, which repre sent approximately 50% of all ovarian tumours and approximately 25% of mali gnant ovarian tumours, are outlined. Lymphomas and metastatic tumours shoul d be treated the same as when found in other sites and will not be discusse d further.
