Primary fallopian tube carcinoma is a rare tumor which histologically and clinically resembles epithelial ovarian cancer. Pelvic and para-aortic lymph nodes are often involved but presentation with inguinal lymph node involvement is rare. We report case of a 64 year postmenopausal parous woman who presented with 4 months history of swelling in left groin, excised and confirmed to be metastatic adenocarcinoma. An exploratory laparotomy with total abdominal hysterectomy, omentectomy with pelvic and para-aortic lymph node dissection was done. Uterus, right fallopian tube and ovaries were normal. Left fallopian tube was distended with a mass of 4x4 cms. Histology of left fallopian tube revealed adenocarcinoma. Histology of left and other structures was normal. All lymph node extirpated were negative. Fallopian tube adenocarcinoma rarely presents as metastatic inguinal lymphadenectomy.
