Tumors of the minor papilla are very rare and these tumors have generally been known as neuroendocrine tumors such as carcinoid tumor and somatostatinoma. As these are mostly submucosal tumors, their diagnosis is difficult by just performing endoscopic forceps biopsy, but diagnosis is possible by surgery or endoscopic resection. EUS and ERCP is an essential tool for the diagnosis of these tumors, and abdominal CT or MRI is also useful because there is the possibility of malignant tumors such as carcinoid tumor. For our present two cases, screening endoscopy revealed the polypoid lesion of the minor papilla. EUS disclosed that the submucosal tumor was limited to the submucosal layer and no abnormality was found from the abdominal CT and ERCP. Herein, we performed endoscopic resection for making the diagnosis and treatment. Histologically, these 2 tumors were diagnosed as ectopic pancreas and gangliocytic paraganglioma, respectively.
