Multi Centricity of Oral Verrucous Carcinoma: A Case Series of 22 Cases.

Verrucous carcinoma (VC) is an uncommon variant of squamous cell carcinoma characterized by proliferative outgrowing clinical appearance of the tumor, Incidence of VC is 2-12 % among oral cancers, the true incidence of VC can be accessed only from surgically treated cases since thorough processing of the entire tumor is necessary for accurate diagnosis, foci of invasive squamous cell carcinoma are found often in the substance of these tumors, thus, over reporting of this tumor is not uncommon. The retrospective data of a tertiary cancer hospital was analysed to understand the clinical challenges and outcome of patients with VC. The frequent association of VC with second primary oral cancer (22.7 %) observed in our series highlights the multi centricity of carcinogenesis in these patients.
