The frequency of amyloid deposits associated with squamous cell carcinoma (SCC) and dysplasia in the oral cavity, pharynx and larynx was examined. In addition, the origin of amyloid proteins by immunohistochemical staining with a panel of anticytokeratin monoclonal antibodies was investigated. Amyloid deposits were found in eight of 73 (11.0%) SCC and one of seven (14.3%) dysplasias in the oral cavity, in eight of 22 (36.4%) SCC and zero of two (0%) dysplasias in the pharynx, and in 22 of 37 (59.5%) SCC and four of 10 (40.0%) dysplasias in the larynx. Eight of 12 different cytokeratin (CK) antibodies reacted with these deposits: 34 beta E12 (CK1, -5, -10, -14) reacted with amyloid deposits in 19 of 19 cases (100%), LL002 (CK14) in eight of 18 cases (44.4%), MNF116 (CK5, -6, -8, -17) in eight of 19 cases (42.1%), D5/16B4 (CK5, -6) in five of 18 cases (27.8%), DE-K10 (CK10) in four of 17 cases (23.5%), RCK108 (CK19) in three of 18 cases (16.7%), 34 beta B4 (CK1) in three of 19 cases (15.8%) and AE8 (CK13) in two of 17 cases (11.8%). These antibodies always reacted with the cytoplasm of squamous cell lesions. Amyloid deposits in two cases contained a CK5 and CK14 pair, and in another two cases they contained both a CK5 and CK14 pair, and a CK1 and CK10 pair. Anti-CK antibodies, including OV-TL12/30 (CK7), c-51 (CK8), DC10 (CK18) and IT-Ks20.8 (CK20) did not react with the amyloid deposits. We conclude that the amyloid deposits associated with SCC or dysplasia in the oral cavity, pharynx or larynx were derived from CK of cancer cells and that some amyloid deposits might be assembled by two or more different CK.
