Hemangiopericytoma is an uncommon tumor derived from pericytes surrounding the vessels. It is a rare tumor in the head and neck, especially in the submandibular region. In general, it is very difficult to diagnose such a tumor before surgical excision. We reported a case of hemangiopericytoma in the left submandibular region. The patient was a 48-year-old man who complained of swelling in the left submandibular region and oral floor. The tumor was removed surgically and proved to be a low-grade-malignancy on histopathological examination. Local recurrence developed 14 months after surgery. We would like to stress that close observation is needed after treatment because of the high rate of local recurrence.
