Immunohistochemical expression of 8 cases of mucoepidermoid carcinomas (G-I, 3 cases; G-II, 2 cases; and G-III, 3 cases) revealed marked heterogeneity of the proteins examined. Immunohistochemically detectable keratins (TK, KL1, and PKK1) were distributed in epidermoid cells, but were absent in mucous secreting cells. Strongly positive deposits of keratin proteins were detected in squamoid tumor cells in the G-I tumors. The tumor cells displayed positive staining for S-100 alpha, but did not stain with polyclonal S-100 antiserum or with monoclonal S-100 beta. The cells showing highest reactivity for S-100 protein were scattered in neoplastic foci and were probably Langerhans cells. Lactoferrin and lysozyme reactions were generally negative in tumor foci; but a positive reaction for lactoferrin was found in luminal tumor cells although rarely, and lysozyme staining was occasionally noted in histiocytes in the stroma. Amylase activity was usually absent in the tumor cells, with the exception of one case in which it was confined to the tumor cells. Mucoepidermoid carcinomas of various grades indicated marked heterogeneity in terms of various immunohistochemically detectable proteins.
