Tumor cells show alterations in their glycosylation patterns when compared to normal cells. Lectins can be used to evaluate these glycocode changes. Chemiluminescence assay is an effective technique for quantitative analysis of proteins, nucleic acids, and carbohydrates due to its high sensitivity, specificity, and rapid testing.<jats:italic>Objective<\/jats:italic>. To use histochemiluminescence based on lectin conjugated to acridinium ester (AE) for the investigation of glycophenotype changes in cutaneous tumors.<jats:italic>Methods<\/jats:italic>. Concanavalin A (Con A), Peanut agglutinin (PNA),<jats:italic>Ulex europaeus<\/jats:italic>agglutinin-I (UEA-I), and<jats:italic>Maackia amurensis<\/jats:italic>agglutinin (MAA) were conjugated to acridinium ester. Biopsies of cutaneous tumors and normal skin were incubated with the lectins-AE, and chemiluminescence was quantified and expressed as Relative Light Units (RLU).<jats:italic>Results<\/jats:italic>. Actinic keratosis (AK), keratoacanthoma (KA), squamous cell carcinoma (SCC), and basal cell carcinoma (BCC) showed lower expression of<jats:italic>\u03b1<\/jats:italic>-D-glucose\/mannose and<jats:italic>\u03b1<\/jats:italic>-L-fucose residues compared to normal tissue. Cutaneous tumors displayed higher expression of Gal-<jats:italic>\u03b2<\/jats:italic>(1-3)-GalNAc residues than normal tissue.

KA and BCC showed equivalent RLU values compared to normal tissue.<jats:italic>Conclusions<\/jats:italic>. Lectin histochemiluminescence allowed quantitative assessment of the carbohydrate expression in cutaneous tissues, contributing to eliminate the subjectivity of conventional techniques used in the histopathological
