Unusual presentation of verrucous carcinoma of maxillary antrum.

Verrucous carcinoma is a rare type of squamous cell carcinoma that is most often seen in the oral cavity and larynx. This paper describes a case report of a rare tumor with an unusual presentation. This patient presented with recurrent pyoceles and was diagnosed by chance. Carcinoma of maxilla is rarely diagnosed until the bony walls are eroded. This condition should be kept in mind in patients presenting with recurrent pyocele and a biopsy carried out from the maxilla.
