Keratinizing squamous cell carcinoma is characterized by the presence of keratinization, pearl formation, and/or intercellular bridges. Non-keratinizing squamous cell carcinoma is characterized by the absence of keratinization, pearl formation, and intercellular bridges. Cigarette smoking and arsenic exposure are strongly associated with squamous cell lung carcinoma."
