[Pelvic hemangiopericytoma in pregnancy. Report of a case].

We report a case of pelvic retroperitoneal hemangiopericytoma (HPC) discovered early during pregnancy. Preoperative diagnosis was obtained by a transvaginal biopsy. Treatment consisted of therapeutic abortion, excision surgery and radiotherapy. In the follow-up examination 32 months after operation, no evidence of tumor recurrence was found. This is the second reported case of HPC complicating pregnancy.
