The malignant lesion may originate as a primary lesion, as a metastasis from a distant organ, or by extension from a proximate site. Early symptoms include nonhealing ulcers, indurated areas, erythematous or white patches, swelling or enlargement, discolorations, dental mobility, hoarseness, and oral bleeding. If the lesion goes undetected, the symptoms can progress to airway obstruction, paresthesias of the tongue, otalgia, trismus, lymphadenopathies, blurry vision, and persistent pain.
