Abstract:

Endometrioid carcinoma of the broad ligament is a rare malignant tumor in a specific site. Due to its low incidence rate, the mechanism, diagnosis and treatment have not been clarified. The clinical manifestations lack specificity and it is often misdiagnosed as uterine or ovarian tumors before surgery. Therefore, this paper reports the diagnosis and treatment of a 65-year-old patient with broad ligament endometrioid carcinoma. Preoperatively, the patient was misdiagnosed as an ovarian tumor, but the diagnosis was confirmed through surgical exploration and postoperative pathology. The patient underwent a second surgery which was a comprehensive staging. Currently followed up for seven months，the patient recovered well, and showed no abnormalities in imaging examination and normal tumor indicators. With retrospective analysis of this case, when gynecological examination revealed the fixation of the tumor in the adnexal area, combined with imaging findings indicating clear boundaries of the tumor, it is necessary to consider the possibility of a broad ligament tumor and surgery should be performed as soon as possible. Once diagnosed with endometrial carcinoma of the broad ligament, timely and comprehensive staged operation should be performed, and long-term follow-up should be conducted after surgery.
