Fibromatosis of the female pelvis.

Fibromatosis is a benign, infiltrating, nonmetastasizing neoplasm which is rarely completely resected. Therefore, the incidence of recurrence is high. Fibromatosis is more common in females and is frequently diagnosed during pregnancy. Inasmuch as fibromatosis of the female pelvis appears to be a discrete entity, management poses significant problems for the gynecologist. Radiation therapy, frequently used following incomplete resection or for recurrence, is undesirable due to the loss of ovarian function and fertility. Hormonal manipulation and combination chemotherapy are alternatives which have been effective in some reports. Three patients with pelvic fibromatosis, referred within 1 year, are reported. The various aspects of this neoplasm and the diagnostic procedures are discussed. Treatment modalities whose effects are reversible are recommended for recurrent fibromatosis. Radiation therapy can be reserved for patients in the older age groups or for those with progressive disease not responding to other therapy.
