Juvenile psammomatoid ossifying fibroma (JPOF) is an uncommon benign and locally aggressive tumor. We report an unusual head tumour with extremely rare extensiveness and aggressivness. The patient was 18-year-old female with three-day-lasting headache and repetitive oral bleeding. Computed tomography revealed a large, well-circumscribed, expansile mass occupying ethmoid cells, nasal cavities and ventral part of the sphenoid sinus, with extention into the anterior cranial fossa. Pterional craniotomy was carried out. On one-year follow-up recurrence of the lesion was identified and the second surgery was performed. The lesion is under supervision now, due to incomplete removal.
