The pathology most consistent with cysts of the large-volume category and thus requiring surgery is serous cystadenoma.
15) Grossly, serous cystadenoma is a well-delineated, multiloculated mass with small individual cysts separated by thin fibrous walls (Figure 1, B and C).
Although seen in less than 20% of lesions, demonstration of a central scar by CT or MR is a highly diagnostic feature of a serous cystadenoma.

For practical use with cytology specimens, this list can be narrowed down to a little more than 10 lesions (Table 1) including ductal adenocarcinoma (and its variants), cellular epithelioid neoplasms (ie, acinar cell carcinoma, pancreatic endocrine neoplasm [specific functioning endocrine neoplasms are best defined clinically], solid-pseudopapillary neoplasm, and pancreatoblastoma) mucus-producing cystic neoplasms (ie, IPMN and MCN), serous cystadenoma, nonepithelial tumors, and metastases.
Serous cystadenoma (SCA) is a benign neoplasm composed of uniform glycogen-rich epithelial cells that form innumerable small cysts containing serous fluid.
Serous, cuboidal, clear cells with uniform, round hyperchromatic nuclei indicate a serous cystadenoma (Figure 18), which can be either microcystic or macrocystic.
