Extraorally proliferating verrucous carcinoma of buccal mucosa mimicking squamous cell carcinoma: A rare case presentation

Abstract

Verrucous carcinoma (VC) (Ackerman's tumor/Snuff dipper's cancer) is a variant of oral squamous cell carcinoma (SCC) with minimum aggressive potential. The most common sites of involvement in the head-and-neck regions are oral cavity and larynx. VC of the oral cavity is a different clinicopathologic tumor distinguished from the usual SCC because of its local invasiveness, nonmetastasizing behavior, and special clinical appearance, but long-standing cases have shown transformation into SCC. An accurate pathological diagnosis is difficult because of an inadequate tumor sample for the study, and more importantly, a close collaboration is needed between a clinician and a pathologist to achieve the correct diagnosis. In this article, we discuss a case of 42-year-old male with VC of the left buccal mucosa which was proliferating extraorally.
