Microcystic Adenoma

slide 3 of 11


Comments:
Serous microcystic adenomas are solitary, well-circumscribed lesions, with size ranging from 1-25 cm in greatest dimension (average, 6-10 cm). Cut surface is sponge-like and made up of numerous cysts filled with serous (clear watery) fluid, giving it a soap bubble pattern. Cysts can be arranged around a para-central or centrally located fibronodular core from which thin fibrous septa radiate to the periphery (central stellate scar). The neoplasms occur most frequently in the body or tail of pancreas with the remaining tumors involving the head of the pancreas. Communication with the pancreatic duct is rare.
