The Hemangiopericytoma is a malignant vascular tumor arising from mesenchymal cells with pericytic differentiation. Hemangiopericytoma is most commonly seen in adults, and only 5% to 10% of cases occur in children. The tumor is extremely rare in the head and neck region (16%)1. Cytogenic abnormalities have been present in some hemangiopericytoma cases. Surgical resection remains the mainstay treatment. Adjuvant chemotherapy and radiotherapy is appropriate for cases of incomplete resections and life-threatening tumors particularly in children. Late relapses may occur and require long-term follow-up. A 4-year-old child patient with hemangiopericytoma of the maxilla presented with firm, recurrent, but painless jaw mass. Radiographic investigations revealed a poorly circumscribed radiolucency. The lesion biopsy showed well-circumscribed multiple lobules of tumor mass consisting of tightly packed, spindle-shaped cells. Chemotherapy and radiotherapy of the lesion was conducted. The role of the pediatric dental team is extensive in children with hemangiopericytoma, who require a regular dental review. The patient's oncologist should be immediately contacted if there is any suspicion of recurrence.
