Polymorphous low-grade adenocarcinoma of the parotid gland

J Cancer Res Ther. 2011 Jan-Mar;7(1):84-7. doi: 10.4103/0973-1482.80464.

Abstract

Polymorphous low-grade adenocarcinoma (PLGA) has been recently recognized as a distinct entity with a known predilection for minor salivary glands. We present an unusual case of recurrent PLGA arising within the right parotid gland in a 25-year-old lady. The striking histological picture is diverse architecture combined with benign cytological features. Even in the light of multiple recurrences, our tumor displayed a relatively indolent course which is commonly associated with this adenocarcinoma sub-type. Thus, unusual occurrence demonstrates that this tumor should also be considered in differentials of tumors of the major salivary glands. Long-term follow-up is essential to ensure local control.
