Ameloblastic fibrosarcoma of the maxillary sinus in an infant: a case report with long-term follow-up.
Ameloblastic fibrosarcoma (AFS) or ameloblastic sarcoma is an extremely rare odontogenic neoplasm. The authors report AFS in the maxillary sinus of a 4-month-old boy. The tumor was composed of odontogenic epithelium, resembling that of ameloblastoma, and a mesenchymal part exhibiting features of fibrosarcoma. We also found some areas with deposition of dentinoid material closely adjacent to the ameloblastic epithelium. Although AFS has occurred in a wide age range, this is the first report of this tumor in infancy with long-term follow-up.
