[A Case of Synchronous Multi-Centric Invasive Ductal Carcinomas of the Pancreas].

A 69-year-old man with left upper abdominal pain visited our hospital. Abdominal CT revealed a hypovascular mass(66× 57mm)in the pancreatic tail. MRI revealed hemorrhage and cysts in the caudal lesion of the tumor. The tumor involved the posterior wallof the stomach. Based on a diagnosis of pancreatic tailcancer with gastric posterior wallinvasion, distalpancreatectomy and partialgastrectomy were performed. Histopathologicalexamination indicated 2 adjacent tumors through a capsule in the pancreas tail. These tumors were diagnosed as synchronous invasive ductal carcinomas of the pancreas, which were anaplastic and papillary carcinomas. We report a rare case of synchronous multi-centric invasive ductalcarcinomas of the pancreas.
