Cribriform adenocarcinoma of minor salivary gland: A mimic of polymorphous low-grade adenocarcinoma

Adenocarcinoma is relatively less common on the tongue.[1] Polymorphous low‐grade adenocarcinoma (PLGA) is a malignant tumor of minor salivary glands which is slow growing and carries a low metastatic potential. Histologically, PLGA exhibits a spectrum of growth patterns such as cribriform, tubular, trabecular, fascicular and solid structures. Concentric whorls forming target‐like patterns are noted as prominent finding. The nuclear features appear to be bland. Invasion of the perineural spaces and other adjacent tissues is typical. Despite this invasive growth pattern of PLGA, the overall prognosis remains to be favorable.[2,3]
