Abstract
An adenocarcinoma arising from the right soft palate of a 72-year-old male was examined by immunohistochemistry, and was reported.
Review of the literature revealed that the incidence of adenoc arcinoma in salivary gland tumors ranged from 0% to 7.5%. It was 3.3% in all minor salivary gland tumors in our department. Thus, adenocarcinoma of the salivary gland is relatively rare. According to the subclassification of adenocarcinoma by Seifert, the present case belonged to solid type. Immunohistochemically, CEA was moderately-to-strongly positive in tumor cells and was found useful as a tumor maker for this tumor. Lactoferrin and EMA were also positive in tumor cells.
