<br>Microcystic serous cystadenoma of pancreas in a 62 year old woman. A. The tumor showed a central scar with multiple minute cysts; slight pressure yielded clear fluid. B. The mass comprises microcysts numberless. C. Cysts bear single cell linings with bland, amitotic nuclei. D. PAS without diastase shows positive cytoplasmic material. E. PAS with diastase shows the cytoplasmic material has been digested away. F. Keratin shows positive staining lining cells. | |||
