title: Polymorphous low-grade adenocarcinoma arising in the nasal cavities with an associated undifferentiated carcinoma.
abstract: A case of polymorphous low-grade adenocarcinoma arising in the right nasal cavity of a male patient with previous history of kidney transplantation is reported. The tumor contained extensive areas of undifferentiated carcinoma, probably arising from the low-grade component. This combination of findings has not been previously reported in this variety of salivary gland tumor.
