An unusual mass of nasal cavity: recurrent glomangiopericytoma.

Hemangiopericytomas are rare tumors of sinonasal region. In this article, we described a case of recurrent mass in right nasal cavity which presented with nasal obstruction and intermittent epistaxis. Patient had a surgical history on the same nasal region without any histopathological document. Abnormal bleeding was observed during surgery and mass was partially removed for histopathological investigation. The result was glomangiopericytoma of the sinonasal region. Although extended surgery was recommended to the patient including preoperative and perioperative measures for bleeding problem, patient preferred to follow-up rather than removal. The clinical progress and review of glomangiopericytoma have also been discussed.
