Hemangiopericytoma (HP) is a rare tumor of uncertain malignant potential. It is arising from mesenchymal cells withpericytic differentiation. It is a vascular tumor which comprises only 1% of all vascular tumors. The frequency ofoccurrence in the head and neck accounts for about 16-33% of all hemangiopericytomas. It usually presents in 5th to6th decade of life. Generally, it presents in nasal cavity, oral cavity, orbit, jaw, parotid gland, parapharyngeal space, andjugular foramen. Most common sites are limbs, pelvis and head and neck. Long term follow up is important because ofimprecise nature of the histological criteria for prediction of biologic behavior. We report a case of HP in 42-year-oldman, and the importance of pathologic examine on polypoid masses in the nose is stressed.

Hemanjiyoperisitom (HP) malign potansiyeli belli olmayan ve nadir görülen tümördür. Perisitik hücre olarak tanımlanan mezenkimal hücrelerden kaynaklanır. Tüm vasküler tümörlerin sadece %1'ini oluşturur. Tüm hemanjiyoperisitomlar, baş boyun tümörlerinin yaklaşık %16-33’ünü oluşturmaktadır. Genellikle hayatın 5. ve 6. on yılında görülür. Genellikle nazal kavite, orbita, oral kavite, çene, parafaringeal alan ve foramen jugularede tanımlanmıştır. Baş, boyun, pelvis ve ekstremiteler yaygın bulunduğu alanlardır. Bu vakalarda biyolojik davranış tahmin etmek güç olduğundan dolayı uzun süreli takip önemlidir. Biz, burun polipoid kitleler üzerinde patolojik incelemenin önemini vurgulamak için 42 yaşındaki erkek hastayı sunduk.
