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. G. Cellular ovarian stroma appeared beneath epithelium of a separate focus of the cystic neoplasm. | |||
