Brenner tumours are an uncommon subtype of the surface epithelial-stromal tumour group of ovarian neoplasms. The majority are benign, but some can be malignant.
They are most frequently found incidentally on pelvic examination or at laparotomy. Brenner tumours very rarely can occur in other locations, including the testes.
