title: Nasal hemangiopericytoma--a case report.
abstract: A case of rare intranasal hemangiopericytoma in a 68-year-old male was reported with typical histological and ultrastructural findings. The lesion clinically resembled a nasal polyp. The experience in the present case raised the need for differential diagnoses of vascularised spindle cell tumors and of traditional hemangiopericytoma in soft tissue.
