Juvenile psammomatoid ossifying fibroma of maxillary sinus: case report with review of literature.

Juvenile psammomatoid ossifying fibroma is a rare benign fibro-osseous tumor of the gnathic and extragnathic craniofacial bones, particularly the periorbital, frontal and ethmoid bones. It is slowly progressive with aggressive local growth, invasion and destruction of the surrounding tissue, bone erosion and recurrence after surgical excision. It is distinguished from the other fibro-osseous lesions by its age of onset, clinical presentation and aggressive behavior.
