Recurrent polymorphous low-grade adenocarcinoma manifesting as a sinonasal mass: a case report.
Polymorphous low-grade adenocarcinoma (PLGA) is a malignant neoplasm that tends to follow a benign clinical course. Recurrences are uncommon. We report a case of recurrent PLGA of the paranasal sinuses that manifested as a large mass that filled the entire nasal cavity and left maxillary sinus. To our knowledge, this is the first reported case of a recurrent PLGA of the paranasal sinuses.
