In epithelial carcinomas, malignant dysplastic epithelium penetrates the basement membrane and enters the connective tissue. These atypical epithelial cells invade the stroma in the form of cords, nests or islands. An exception to this rule is Verrucous carcinoma (VC) where there is no connective tissue invasion by the epithelium. VC has an intact basement membrane and shows endophytic growth pattern.
