A case of pancreatic solid type serous cystadenoma with difficulty in differentiation from pancreatic neuroendocrine tumor

Abstract

A 42-year-old man was admitted to our hospital because of suspicion of a tumor of the pancreatic body based on abdominal CT. He had no complaints. Blood biochemical, tumor marker, and pancreatic endocrine hormone testing yielded no abnormal findings. The tumor was strongly enhanced by abdominal contrast-enhanced CT and MRI. A pancreatic non-functional endocrine tumor was suspected, thus a distal pancreatectomy was performed. The histopathological diagnosis was solid type serous cystadenoma. We report a case of pancreatic solid type serous cystadenoma that was difficult to differentiate from a pancreatic neuroendocrine tumor.
