J. Lloreta et al., POLYMORPHOUS LOW-GRADE ADENOCARCINOMA ARISING IN THE NASAL CAVITIES WITH AN ASSOCIATED UNDIFFERENTIATED CARCINOMA, Ultrastructural pathology, 19(5), 1995, pp. 365-370
A case of polymorphous low-grade adenocarcinoma arising in the right n
asal cavity of a male patient with previous history of kidney transpla
ntation is reported. The tumor contained extensive areas of undifferen
tiated carcinoma, probably arising from the low-grade component. This
combination of findings has not been previously reported in this varie
ty of salivary gland tumor.
