Serous microcystic adenoma (glycogen rich cystadenoma) of the pancreas.

Serous microcystic adenoma (SMCA) is a rare pancreatic tumor with a striking predilection for elderly females and a rather unique morphology. Classically, the tumor is riddled with innumerable small cysts around a stellate scar. The quintessential histological features are closely placed small cysts lined by glycogen rich cuboidal epithelium.
