Case Discussion
The pancreatic serous cystadenoma is an epithelial neoplasm that mostly affects women with a slight predominance in the pancreatic head. The most common presentation is with numerous small cysts that give a "honeycomb" appearance (microcystic variant), thin septa, and sometimes with a central scar.

The serous cystadenoma is always benign
