Primary undifferentiated small-intestine carcinoma is rare and the prognosis is dismal. A 66-year-old man with a history of laryngeal and lung cancer was admitted for slight fever and abdominal pain. Computed tomography (CT) indicated a mass from the mesentery to the small-intestine wall and swollen mesentery lymph nodes, necessitating emergency surgery due to bowel obstruction. Perioperative findings for the ileum 170 cm from the ligament of Treitz showed a 7 cm mass and swollen lymph nodes around the superior mesenteric artery. We conducted dissection and radical surgery. Histopathologically, it had the primary undifferentiated small-intestine carcinoma with the lymph nodes metastasis diagnosed by immunostaining. The postoperative course was good and the man was discharged on postoperative day 19. No recurrence has been seen in the 37 months since.
