Sinonasal hemangiopericytoma-like tumor の1例

抄録

A 72-year-old woman came to our hospital complaining of bilateral nasal obstruction. Nasal fiberscopy, MRI, and a biopsy of the left nasal tumor were performed, and the preoperative diagnosis was benign nasal tumor of vascular origin. Intranasal resection of the tumor was performed, and the histological diagnosis was sinonasal hemangiopericytoma-like tumor. Such tumors differ from hemangiopericytomas of other regions in terms of the clinical and pathological findings, but some of the immunohistochemical findings resemble those of glomus tumor.
