Background:
Extrauterine endometrial stromal sarcoma (ESS) is a rare neoplasm. Little is known about its pathophysiology or best treatment approach.
Case:
We are describing a case of extrauterine ESS in a 70-year-old woman on hormone replacement therapy and with a history of endometriosis. We also present a brief review of the literature on ESS and its relationship to endometriosis and hormonal therapy.
Conclusions:
Complete resection should remain the treatment of choice for ESS. Unresectable or metastatic low-grade ESS may respond well to progestin therapy, but outcomes of high-grade ESS tend to be poor.
