Hemangiopericytoma (HPC) is an uncommon vascular tumor arising from pericytic cells with variable malignant potential. Primary HPCs of the bone are extremely rare; however, involvement of the condylar process has not been reported. We presented a 21-year-old female patient with low-grade malignant HPC in the right mandibular condyle. Clinical examination and imaging findings revealed a well-defined soft mass, encapsulating the mandibular condyle from behind. The lesion and mandibular condyle were removed simultaneously; then, the costochondral graft was used to reconstruct the defect. Histopathologic examinations of the specimen confirmed the diagnosis. After 2 years of follow-up, the patient is free of disease, and mouth opening returned to normal.
