Abstract
The patient was a 16 year-old boy who complained of swelling of the left cheek. Surgical treatment (Caldwell-Luc technique) was performed under general anesthesia. A large tumor was found in the left infratemporal fossa which was compressing the maxillary sinus and extended to the superior orbital fissure. The tumor was removed completely with minimum blood loss. Histological examination showed hemoangiofibroma with collagen fibers in the center and numerous vessels in which the thromboses were partially scattered.
