The authors report the resected case of a adenosquamous carcinoma of the duodenum. In a 77-year-old man referred for investigation of anemia, upper gastrointestinal endoscopy revealed a tumor in the second portion of the duodenum. The endscopic biopsies showed adenocarcinoma and squamous cell carcinoma. Imaging studies and the operative findings disclosed that the tumor had invaded the head of the pancreas, portal vein and the transverse colon. Pancreaticoduodenectomy combined with right hemicolectomy was performed. The specimen revealed adenosquamous carcinoma of the duodenum. The patient has been well without any evidence of recurrence for 5 years after the surgery. A review of the literature and discussion about the histogenesis is included.
