Intravascular papillary endothelial hyperplasia (Masson's tumour) of gynaecological origin

Intravascular papillary endothelial hyperplasia or Masson's tumour is a non -neoplastic vascular lesion of reactive character. It is a rare diagnosis, clinically non-specific and with diverse locations. It is essential to take it into consideration and make a differential diagno-sis with malignant vascular tumours such as angiosarcoma. Pathological study is fundamental for diagnosis. Treatment consists of complete resection of the tumour, including sufficiently wide margins to avoid recurrence. The case reported is an exceptional event, because of the pelvic location of the Masson'stumour that was diagnosed as part of the surgical staging of an ovarian cancer.
