Salivary glands are origin organs of a great number of lesions with different histopathologic patterns. Neoplasias of salivary glands constitute with 3% of total head and neck neoplasias in adults and with 8% in children. Cytokeratin expression is related to programed sub-expression of cell types during embrionary development and cell differentiation in many human tissues. Lectins are carbohydrate recognition proteins which agglutinate cells.This work aims to evaluate the expression of cytokeratins and carbohydrate profile in Warthin's tumours using immunohistochemistry and lectin histochemistry. Tissue slices (4mm) after deparaffinization and hydration were stained using antibodies (anti-Cks 7, 8, 14, 19, anti-vimentin and anti-smooth muscle actin, SMA) in the streptavidin-biotin-peroxidase technique and lectins conjugated to horseradish peroxidase, HRP (Ulex europaeus I agglutinin, UEA-I; Concanavalin A, Con A). Ck7 and Ck8 stained intensely the ductal estructures of tumour remaining, normal tissue and the neoplasic ducts. Meanwhile Ck7 also stained covering epithelium in the cistic spaces, Ck8 did not react to the same structures. Ck14 failed to recognize tumour cell and Ck19 reacted weakly only in epithelial islets and covering epithelium of Warthin's tumour. Vimentin and SMA were negative for tumour cells but vimentin presented an intense pattern for tumour stroma. Con A recognized neoplasic cells presenting an intense homogeneous and perinuclear staining pattern. Cistic space, vascular and remaining endothelium were Con A stained with a pattern varying from weak to moderate. Neoplasic cells were UEA I stained in a perinuclear, membrane,  homogeneous and intense pattern. UEA I did not recognized the normal remaining epithelium but stained intensily and moderately the tumour stroma and cell apical region of the cistic spaces, respectively.  The results showed that lectin histochemistry brings new characteristics for Warthin's tumour diagnosis not presented by cytokeratin immunohistochemistry.
