Fibrosarcoma of the vulva: case reports and discussion.

Three cases of fibrosarcoma of the vulva are reported. In two, surgical resection resulted in remission lasting over four years. In the third case, presenting with metastasis of the lung and liver, the patient died without surgery having been carried out. The low mitotic index found in the first two cases seems to lead to a favourable prognosis, whereas the inferior vulvar localization found in the last case seems to be more dangerous because of its diffusion into the paravaginal space.
