Management of non-epithelial ovarian tumours.

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