title: Nasal hemangiopericytoma.
abstract: Nasal hemangiopericytoma is difficult to diagnose preoperatively or before examining a histologic specimen. It is a locally invasive tumor with an excellent five-year prognosis, but which requires lifetime follow-up. The patient reported was treated by aggressive local surgical treatment of the tumor followed by systemic therapy for multiple myeloma.
