Abstract

Specimens are assigned to the negative category when the specimen does not contain any material indicative of malignancy or any degree of cellular atypia. Specimens containing only normal pancreatic tissue are assigned to this category only when there is no discrete mass or cystic lesion. Correlation with imaging findings is required for placing a specimen in this category. Specific nonneoplastic entities placed in this category include acute pancreatitis, chronic pancreatitis, autoimmune pancreatitis, pseudocyst, lymphoepithelial cyst, and ectopic spleen.
