Carcinoma Cuniculatum, a Rare Variant of Oral Squamous Cell Carcinoma: Presentation of Five Clinical Cases and Review of the Literature.

Background: Oral carcinoma cuniculatum (CC) is a rare variant of squamous cell carcinoma. It exhibits a locally aggressive behaviour, and its histopathology poses a diagnostic challenge, as it can be mistaken for other conditions. We present five cases of oral CC treated at our institution and conduct a comprehensive review of the current literature.
