[Oral verrucous carcinoma].

Verrucous carcinoma is a rare, low-grade, well-differentiated form of squamous cell carcinoma seen on skin and mucosa. It is a slow-growing and locally aggressive tumor whose standard treatment is surgery. A case of strongly invasive oral verrucous carcinoma is presented with the medical history. The differential diagnosis of this neoplasm is difficult and requires clinic and pathologic data confrontation. In this paper, the importance of knowing the malignant potential of this lesion is stressed. Indeed, in 20% of verrucous carcinoma, foci of squamous cell carcinoma can be found. A review of literature and a differential diagnosis of verrucous carcinoma are presented.
