Introduction: Primary fallopian tube cancers (PFTCs) are rare gynecological malignancies by the prevalence of 0.3-1%. In this case study, we aimed to discuss the diagnosis and patient s follow-up who was identified with PFTC and inguinal lymph node metastasis. Case report: A 57-years-old G5P5 postmenopausal woman referred to our clinic after right inguinal lymphadenectomy. Metastatic adenocarcinoma was indicated in the pathologic report. Mammography showed fibrocystic changes. Histology evaluation was performed and the result showed the serous papillary carcinoma of the ovary as the origin of the tumor, therefore we performed an exploratory laparotomy for her. In surgery, abdominal and pelvic organs were normal, except the small tumor existing in the end of the right fallopian tube. There was 2 cm tumor in the right fallopian tube without perineural or intralymphatic invasion. Right ovary was free of tumor. All lymph nodes, omentum, and peritoneal washing cystology were negative for malignancies. Discussion & Conclusion: According to previous studies, it is clear that lymphadenopathy is a rare sign of primary fallopian tube cancer and only a few numbers of patients have been reported so far. In summary, as already mentioned, PFTC is an extremely rare problem that makes a challenge for surgeons and its causes are still unknown. So because of the difficulty in the initial diagnosis, after primary surgery and definitive diagnosis of the disease, the surgeons complete the previous surgical procedure by performing an additional surgery, which seems to increase mortality among patients. Hence, more comprehensive studies should be performed to find the effective methods of diagnosis and applying the best medical management protocols to better treatment for the disease and reduce
