title: Juvenile psammomatoid ossifying fibroma with massive mandibular involvement.
abstract: Juvenile psammomatoid ossifying fibroma (JPOF) is a histologic variant of an ossifying fibroma. While an ossifying fibroma varies in appearance, it consists of fibrocellular tissue and mineralized material. JPOF is a rare benign lesion; however, it can be extended locally and mimic a malignant tumor. It is considered a specific clinicopathologic entity, due to its occurrence in children and adolescents, the presence of psammomas, and its purported tendency for local aggressive growth and recurrence. It commonly affects the maxilla, nasal cavity, paranasal sinuses, and ethmoid region. This article describes a rare, aggressive case of a large JPOF that led to the total destruction of the mandible.
