Pathologists classify serous cystic neoplasms into two broad groups. Those that are benign, that have not spread to other organs, are designated "serous cystadenoma". [5] Serous cystadenomas can be further sub-typed into microcystic, oligocystic (or macrocystic), solid, mixed serous-endocrine neoplasm, and VHL-associated serous cystic neoplasm.
Serous cystadenocarcinoma is a serous tumor in the cystadenocarcinoma grouping.. Most commonly, the primary site of serous cystadenocarcinoma is the ovary.Rare occurrence in the pancreas has been reported, although this is not typical, with the majority of microcystic pancreatic masses representing alternate disease processes such as the more benign serous cystadenoma.

Mean age of presentation is at 45 years old. About 30% of biliary cystadenoma can progressively become malignant over time.

A pancreatic cyst is a fluid filled sac within the pancreas. The prevalence of pancreatic cysts is 2-15% based on imaging studies, but the prevalence may be as high as 50% based on autopsy series. [1] Most pancreatic cysts are benign and the risk of malignancy (pancreatic cancer) is 0.5-1.5%.
Cystadenocarcinoma is a malignant form of a cystadenoma and is a cancer derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. The neoplastic cells manifest varying degrees of anaplasia and invasiveness, and local extension and metastases occur.
Serous cystadenoma may refer to: Ovarian serous cystadenoma , a very common benign tumour of the ovary Pancreatic serous cystadenoma , also known as serous microcystic adenoma
