A case of recurrent fallopian tube carcinoma in situ with para-aortic lymph node metastasis
Tóm tắt
We encountered a case of recurrent fallopian tube carcinoma in situ with para-aortic lymph node metastasis 9 months after the first surgery. The patient presented with genital bleeding, and endometrial cytology revealed extrauterine malignant cells. However, endometrial biopsy and imaging modalities could not detect any abnormalities. We performed a total abdominal hysterectomy and bilateral salpingo-oophorectomy after obtaining the patient’s consent. Histopathological examination revealed atypical cells in the fimbrial portion of the fallopian tube. A diagnosis of fallopian tube carcinoma in situ was made. No further adjuvant treatment was administered. Nine months later, fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography revealed pathologic activity in the para-aortic lymph node and CA125 elevation. A diagnosis of metastatic adenocarcinoma was established on the basis of histological examination of a frozen section. The patient underwent para-aortic and pelvic lymph node dissection and omentectomy. The pathology report revealed metastasis to 3 of 69 lymph nodes; however, peritoneal cytology was negative for cancer. To the best of our knowledge, this is the first reported case of recurrent fallopian tube carcinoma in situ.
