A 75-year-old man without symptom visited our hospital for examination of the upper gastrointestinal tract. Upper GI series and endoscopic examination revealed three elevated lesions (Yamada type II, type IV, type I) with central depression in the descending part of the duodenum. Histological examination of biopsy specimens obtained from the central depression of the first lesion disclosed heterotopic gastric mucosa (HGM) and carcinoid. Surgical resection of all tumors was performed, and there was no evidence of metastases. Resected specimens measured 8×8mm, 7×7×13mm, and 3×3mm in size. All of elevated lesions consisted of HGM and only the Yamada type II lesion had carcinoid. HGM is rare in the descending part of the duodenum. From the review of Japanese literatures, this case is the first report in Japan of HGM associated with carcinoid in the duodenum.
