Both basaloid and<unk>  cell carcinomas have been shown to arise from pre-malignant lesions of dysplasia in the airways of the lung. After continued exposure to tobacco smoke or other carcinogenic stimuli, cells in areas of severe dysplasia can suffer additional genetic damage that results in progression to a basaloid or<unk>  cell carcinoma in situ (CIS). CIS is a fully malignant lesion, but by definition, the cancer cells have not yet invaded beyond the tissue delimiting their original site of genesis.
