Serous cystadenomas (SC) of the pancreas are uncommon benign cystic neoplasms that were first differentiated from mucinous cystadenomas in 1978 by Compagno and Oertel [1–3]. SC characteristically have a spongy gross appearance and are composed of innumerable tiny cysts lined by flattened cuboidal or polygonal cells with clear to pale eosinophilic cytoplasm atop of thin fibrous septae. Since 1978, 5 unique SC subtypes have been identified [4–6]. Herein we report a case of a solid serous adenoma, a rare serous cystadenoma subtype.
