and the pancreatic mucinous cystadenoma), serous cystic neoplasms are almost always entirely benign. There are some exceptions; rare case reports have described isolated malignant serous cystadenocarcinomas. In addition, serous cystic neoplasms slowly grow, and if they grow large enough they can press on adjacent organs and cause symptoms.


Signs and symptoms

In most cases, serous cystadenomas of the pancreas are asymptomatic. However, large cysts may cause symptoms related to their size.


Classification

Pathologist Pathology is the study of the causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in th ...
s classify serous cystic neoplasms into two broad groups. Those that are benign, that have not spread to other organs, are designated "serous cystadenoma". Serous cystadenomas can be further sub-typed into microcystic, oligocystic (or macrocystic), solid, mixed serous-endocrine neoplasm, and VHL-associated serous cystic neoplasm. This latter classification scheme is useful because it highlights the range of appearances and the clinical associations of these neoplasms. Serous cystic neoplasms that have spread ("metastasized") to another organ are considered malignant and are designated "serous cystadenocarcinoma".

Treatment

These lesions rarely require

unless they are symptomatic or the diagnosis is in question. Since these lesions do not have malignant potential, long-term observation with imaging surveillance is unnecessary. Surgery can include the removal of the head of the pancreas (a

), removal of the body and tail of the pancreas (a distal pancreatectomy), or rarely removal of the entire pancreas (a total pancreatectomy). In selected cases the surgery can be performed using minimally invasive techniques such as

Epidemiology

Serous cystadenomas of the pancreas are more common in women. SCAs are usually diagnosed in people 50–60 years of age.
