Abstract
Introduction: Verrucous carcinoma of the oral mucosa recurs locally but does not metastasize in the absence of an invasive squamous cell carcinoma component. Clinical Observation: We report a case of an oral verrucous carcinoma in 67-year-old male patient causing bone invasion and bilateral lymph node metastasis despite the absence of a clear squamous cell carcinoma component. Discussion: Some verrucous carcinomas show dysplasia with very minor component of conventional squamous cell carcinoma. Currently, there is great challenge in diagnosing those “in between” tumor type because of the lack of standard nomenclature and studies assessing their clinical behavior.
