title: The immunoexpression of EGFR and Her2/neu in oral squamous carcinoma.
abstract: In this study, we have analyzed the EGFR and Her2/neu expression in oral squamous carcinoma and adjacent dysplastic areas. The lesions were diagnosed especially in the sixth decade of life, in male patients, localized on the lips, especially as well and poorly differentiated carcinomas (34%). The EGFR immunostain has been intense in over 50% of the tumors cells in well-differentiated carcinomas, expression diminished in the moderately and poorly differentiated carcinomas. Her2/neu marker recorded a score of 3+ in moderately and poorly differentiated carcinomas, the reaction turning out positive in 25% of the cases.
