Abstract

<p>A 79 year old male was evaluated for a pancreatic tumor found at screening and was referred for further evaluation. Blood tests showed an elevated gastrin level, but tumor markers were within normal limits. Computed tomography scan of the abdomen showed an 8mm tumor in the pancreatic body in the early phase. The tumor was the same radiodensity as the artery, and had grown over 4 years. An aneurysm was suspected and abdominal angiography was performed. The tumor was not an aneurysm and was suspected to be a nodular hypervascular tumor. Endoscopic ultrasound showed similar findings, and although biopsy was considered, it was not performed because of the possibility of bleeding. Distal pancreatectomy was performed for the purpose of diagnosis and treatment. In the tumor, vascular endothelial-like cells without atypia proliferated forming a large vascular cavity, and was diagnosed as a pancreatic cavernous hemangioma considering the immunohistochemistry findings. Pancreatic hemangiomas are rare and the present patient is reviewed with cases reported in Japan.</p>
