Benign mucinous cystic neoplasm of pancreas in a 62 year old woman. A. CT scan showed a peripherally calcified spheroidal mass at the tail of the pancreas. Cytology only showed debris and inflammatory cells, but CEA of the fluid was 2875.2 ng/mL. B. Almost all sections of the cyst showed acellular debris topping a fibrous, often calcified wall, consistent with a pseudocyst. C. Extensive sampling, undertaken because of the high CEA, revealed rare sections with a lining. D. Lining nuclei are bland, with even chromatin. Shape and size variation, as well as darkening when shrunken, are all explicable by degeneration. E. Within distal pancreas, a focus of changes of chronic pancreatitis is seen upper left, while a pancreatic duct in lower right shows an intraductal proliferation. F. Tumor cells show mucinous vacuoles, with better preserved nuclei. Nuclear appearances remain bland. Ovarian type stroma was not seen. | |||
