Immunohistochemical detection of carcinoembryonic antigen (CEA) in parotid gland carcinomas. Analysis of 52 cases.
The presence of CEA in parotid gland tumours was studied by immunohistochemical methods. 52 cases were analysed. 7 of 8 adenocarcinomas, 3 of 5 cystadenocarcinomas, 3 of 4 adenoid cystic carcinomas and all 3 salivary duct carcinomas were positive for CEA. 5 of 8 squamous cell carcinomas and 9 of 21 carcinomas in a pleomorphic adenoma were also positive for CEA. The anaplastic carcinomas were negative. The distribution pattern of the presence of CEA in the carcinomatous and the adjacent normal or inflamed tissue was analysed. The results are discussed with regard to their histogenetic and diagnostic implications.
