Invasive squamous carcinoma is characterized by infiltrating tongues and nests of atypical squamous cells invading into the submucosa that are almost always accompanied by an desmoplastic stromal response. It is usually accompanied by keratinization (squamous pearl formation), increased mitotic activity, and significant cytologic atypia. Carcinoma is graded as well-differentiated, moderately differentiated, or poorly differentiated based on the degree of squamous differentiation.
