In nasal and paranasal malignant tumors, non-epithelial tumors are frequently observed rather than squamous cell carcinoma.Recently, we treated a rare case of hemangiopericytoma originating in the left maxillary sinus.As reported the clinical findings are described and statistical analysis of this disease in the literature is also made.The patient was a 62-year-old male who complained of epistaxis. At first, his nasal cavities showed no pathologic tumors, and X-ray examination revealed no particular changes in his paranasal sinuses.Four months afterwards, he felt swelling and pain in the region of his left cheek without visible disturbance, and X-ray films showed a diffusely clouded shadow in his left maxillary sinus.Several biopsies were performed from the sinus tumor, and the first pathological report indicated no malignancy, but his clinical signs strongly suggested a malignant tumor. Therefore, chemotherapy was administered and the diagnosis of hemangiopericytoma originating from the paranasal sinus was pathologically made during treatment.Six months afterwards, he died of rapid recurrence and secondary general metastasis in spite of surgery, radiation and chemotherapy. We analysed the clinical pathological findings in 8 patients with hemangiopericytoma in the nasal and paranasal cavities in Japan.
