The expression of p53 protein and PCNA was immunohistochemically examined in 161 cases of salivary gland tumors. The p53 protein was positive in 23.8% (24/101) of malignant salivary gland tumors, while only one case of 60 pleomorphic adenomas was positive. p53 protein was frequently detectable in salivary duct carcinoma (60%), basal cell adenocarcinoma (66.7%), acinic cell carcinoma (53.3%) and undifferentiated carcinoma (50%), but was rarely seen in adenoid cystic carcinoma (17.2%) and mucoepidermoid carcinoma (0%). p53 protein was more frequently detectable in PCNA positive cases than in negative cases (p=0.0074).
