Hemangiopericytoma of the parotid gland: a case report.

Hemangiopericytomas are uncommon neoplasms of vascular origin that mostly arise from extremities, retroperitoneum, and pelvic fossa. They are rarely found in the parotid gland. A 35-year-old female patient presented with a swelling in the right preauricular region. Fine-needle aspiration biopsy performed twice yielded an extraordinary amount of blood. A cytological diagnosis could not be made. Computed tomography showed a homogenous, well-shaped mass in the parotid gland. Superficial parotidectomy was performed. Histopathological diagnosis was made as hemangiopericytoma. No evidence for local recurrence or distant metastasis was seen within a follow-up of 36 months.
