Abstract

The macrocystic form of serous cystadenoma of the pancreas is an uncommon benign neoplasm composed of few, relatively large cysts that are lined by uniform, glycogen-rich, cuboidal epithelial cells. We report here on two cases of pathologically proven macrocystic serous cystadenoma of the pancreas in a 45-year-old female patient and a 53-year-old female patient. Both these cysts were lined by low cuboidal epithelia without any evidence of mucin production. There was also no evidence of pancreatitis. These tumors were radiologically suspected as being mucinous cystic neoplasm or pseudocysts. Although the microscopic and immunohistochemical studies of the macrocystic variant are not different from the conventional serous microcystic cystadenoma, their unusual macroscopic features can lead to confusion for the clinicians and radiologists.
