Primary Fallopian Tube Cancer: An Unusual Case of Inguinal Lymphadenopathy

Background: Primary fallopian tube cancers (PFTCs) are rare gynecological malignancies by the prevalence of 0.3-1%. The PFTCs occur in individuals within the age range of 18-88 years, more specifically at the age range of 40-65 years with the mean age of 55 years. The PFTC usually is observed with the chronic inflammation of the fallopian tube, infertility, tuberculous salpingitis, and tubal endometriosis. This study aimed to discuss the diagnosis of PFTC and the follow-up procedures of such patients. Moreover, it investigated inguinal lymph node metastasis as an uncommon occurrence and also reported a review of the literature about PFTC. Case report: The case in this study was a 57-year-old woman (G5P5) referring to the clinic of Imam Hospital of Sari, Iran, in May 2016 after right inguinal lymphadenopathy. Total bilateral salpingo-oophorectomy with omentectomy, abdominal-hysterectomy, exploratory-laparotomy, as well as pelvic and para-aortic lymphadenectomy were performed for the patient. The pathogenic report indicated metastatic adenocarcinoma of a small tumor at the end of the right fallopian tube. Conclusion: Since it is difficult to conduct initial diagnosis after primary surgery and definitive diagnosis of the disease, the surgeons complete the previous surgical procedure by performing an additional surgery. However, this issue seems to increase mortality among patients. As a result, it is essential to conduct more comprehensive studies to find the effective methods of diagnosis and apply the best medical management protocols for a better treatment of the disease, and therefore reduce mortality.
