Oral verrucous carcinoma and ameloblastoma: a rare coincidence.
BACKGROUND
Oral verrucous carcinoma (OVC) is a rare malignancy of the oral cavity that was first described by Ackerman. This tumor is a well-differentiated low-grade, slow growing cancer that is locally invasive without metastasis. Ameloblastoma is one of the most common odontogenic tumors, which originates from the odontogenic epithelium. Verrucous carcinoma along with central ambloblastoma is a rare phenomenon.


METHODS
A case of verrucous carcinoma along with central ambloblastoma in a 49-year-old man, which was referred with a painless exophytic lesion with a verrucous and granular surface, is reported. Panoramic radiography revealed a well-defined radiolucency with sclerotic borders. To the best available knowledge, this phenomenon has not yet been reported.


CONCLUSIONS
Verrucous carcinoma could occur in the wall of odontogenic cysts and tumors and should be considered during the differential diagnosis of a radiolucency, which is observed in the jaws with rapid growth or which presents some changes from its previous appearance.
