The majority of human tumors arise from epithelial tissues (carcinomata). Most carcinomata are derived from either epithelial cells with secretory specialization (adenocarcinomata) or epithelial sheets that form protective surfaces (squamous cell carcinomata). Squamous cells are characterized histologically by keratinization and the presence of intercellular bridges. Beneath the epithelial cell layers lies a basement membrane (basal lamina) that separates them from the underlying layer of connective tissue cells (stroma). The disruption of the basement membrane is an early sign of carcinoma invasiveness.
