Diagnosis of endometrioid adenocarcinoma of the fallopian tube misinterpreted as ovarian cancer: a case report
Tóm tắt
Primary fallopian tube cancer is a rare gynecologic malignancy, often misdiagnosed as ovarian cancer due to overlapping clinical and radiologic features. We report a case of a 49-year-old woman presenting with abnormal uterine bleeding and lower abdominal pain. Imaging revealed bilateral adnexal masses and elevated CA 125, HE4, and Risk of Ovarian Malignancy Algorithm (ROMA) index. Surgical exploration identified a left fallopian tube tumor and omental involvement. Histopathology confirmed high-grade endometrioid adenocarcinoma of the left fallopian tube with metastatic deposits. The patient underwent total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and adjuvant chemotherapy with Paclitaxel and Carboplatin. This case underscores the diagnostic challenge and clinical significance of recognizing fallopian tube carcinoma in patients with adnexal masses and elevated tumor markers.
