Low-grade cribriform cystadenocarcinoma of salivary glands

Definition: Low-grade cribriform cystadenocarcinoma (LGCCC) is a rare tumor of salivary gland which exhibits clinically indolent behavior.

This tumor predominantly consists of intraductal components and frequently exhibits papillary-cystic or cribriform proliferation pattern.

Considering the histological features of LGCCC, it should be distinguished with :
- papillocystic variant of acinic cell carcinoma
- conventional salivary duct carcinoma
- cystadenocarcinoma
- polymorphous low-grade adenocarcinoma
- carcinoma ex pleomorphic adenoma
- mammary analogue secretory carcinoma (MASC)
