This case report describes a 35-year-old woman who presented with hematochezia and anal pain, initially receiving an incorrect diagnosis of a rectal stromal tumor. Through multiple multidisciplinary team meetings, clinicians identified the condition as extrauterine endometrial stromal sarcoma arising from deep pelvic endometriosis, which was subsequently treated with gonadotropin-releasing hormone agonists to shrink the lesion before surgical resection. The authors emphasize that such collaborative diagnostic approaches are crucial for accurately identifying rare malignancies and improving patient quality of life. This paper is centrally about endometriosis — specifically, the malignant transformation of deep infiltrating endometriosis into extrauterine endometrial stromal sarcoma.

Abstract

INTRODUCTION: Extrauterine endometrial stromal sarcoma (EESS) arising from Deep pelvic endometriosis (DPE) has a poor life quality and is difficult to diagnose pre-operatively. However, the patient's quality of life can be improved when it is diagnosed precisely and managed successfully. CASE REPORT: A 35-year-old woman presented to our hospital with a 3-month history of hematochezia and anal pain. Initially, she was misdiagnosed as a rectal stromal tumor and then precisely diagnosed as having EESS from DPE following several multidisciplinary team (MDT) meetings. The lesion was shrunk by gonadotrophin-releasing hormone agonist (GnRH-α) treatment and then resected with minimal trauma. CONCLUSION: MDT is crucial in the treatment of the patient. It can promote individualized treatment and improve patient's quality of life.

Abstract

Introduction: Extrauterine endometrial stromal sarcoma (EESS) arising from Deep pelvic endometriosis (DPE) has a poor life quality and is difficult to diagnose pre-operatively. However, the patient’s quality of life can be improved when it is diagnosed precisely and managed successfully. Case Report: A 35-year-old woman presented to our hospital with a 3-month history of hematochezia and anal pain. Initially, she was misdiagnosed as a rectal stromal tumor and then precisely diagnosed as having EESS from DPE following several multidisciplinary team (MDT) meetings. The lesion was shrunk by gonadotrophin-releasing hormone agonist (GnRH-α) treatment and then resected with minimal trauma.

Conclusion

MDT is crucial in the treatment of the patient. It can promote individualized treatment and improve patient’s quality of life.
