Intraosseous mucoepidermoid carcinoma of the maxilla in a teenager: a case report and review of literature.

Central mucoepidermoid carcinoma is a rare central bony lesion in teenagers. We report on an 11-year-old girl with a central pathologic lesion in the right hemimaxilla.

A study of the relationship between ameloblastoma and human papilloma virus.

PURPOSE: The purpose of this study was to determine the relation of ameloblastoma with one of its probable etiologic factors, human papilloma virus (HPV). MATERIALS AND METHODS: This study was carried out in a retrospective, observational, and blind manner with information forms using an exact polymerize chain reaction. Fifty paraffinated blocks of ameloblastoma tumor were compared with 50 impacted third molar follicles. RESULTS: The results indicate that statistically the incidence of HPV positivity in the case group is significantly higher than that in the control group (P <.025). Furthermore, in determination of trace HPV type in HPV-positive samples, the incidence of type 6 HPV in the case group is significantly higher than that in the control group (P <.005). None of types 8, 11, 16, 18, 31, and 33 were observed. CONCLUSION: The results of this research conclude that HPV could be regarded as a possible etiologic factor of ameloblastoma.
