Sinonasal haemangiopericytoma: a case report.
Haemangiopericytoma (HPC) is a rare vascular tumour that is thought to originate from the vascular pericytes of Zimmerman. HPC may arise in any part of the body, and from 15 to 30% of these tumours are found in the head and neck, with a rare involvement of the sinonasal region The main symptoms of nasal HPC, epistaxis and nasal obstruction, are not typical. The final diagnosis is based on the histopathology and immunochemistry, and whether the tumour is benign or malignant is defined on the basis of the clinical history. HPC located in the sinonasal area is generally benign. We report the case of a young woman with a sinonasal mass histologically proven to be haemangiopericytoma. The patient underwent surgical treatment by means of mid-facial degloving after embolisation of the maxillary artery. After a careful 3-year follow-up, the patient is disease free and healthy.
