text: Laryngeal<unk>  arises from squamous cells, which are cells that are normally involved in protection of upper respiratory airway. Genes involved in the pathogenesis of laryngeal<unk>  include p16, NOTCH1, cyclin D1, and TP53. On gross pathology, flattened plaques, mucosal ulceration, and raised margins of the lesion are characteristic findings of laryngeal<unk> . On microscopic histopathological analysis, spindle cells, basaloid cells, and nuclear atypia are characteristic findings of laryngeal<unk> .
