Abstract

Sinonasal hemangiopericytoma, also known as glomangiopericytoma (GPC) is a benign perivascular tumor
of low malignant potential, with an incidence rate of 0.5-1% of all sinonasal tumors. It often shows
local recurrences with invasion to the surrounding bony tissues. It usually arises from the perivascular
cells surrounding the capillaries. Etiology of the tumour is uncertain, with few postulated hypothesis like
pregnancy, trauma, hypertension and corticosteroid drugs. They have an indolent course and tend to occur
most commonly in the adults of seventh decade of life. We present a case report of 55 years old male
presenting to the ENT OPD, with complaints of right sided nasal obstruction and repeated episodes of
epistaxis since the last 9 months. History and general examination was unremarkable except for antihypertensive
intake since the last few years. Laboratory investigations showed microcytic hypochromic
anaemia, raised absolute eosinophil count of 1500 cells per microliter and positive Hepatitis B surface
antigen (HBsAg) in the blood. Rhinoscopic examination showed a reddish brown nodular swelling in the
right nasal cavity beneath the middle turbinate and hypertrophy of left nasal mucosa. CT imaging suggested
an 18x15 mms, well defined soft tissue mass in the right nasal cavity. Complete resection of the mass with
endoscopic surgery was performed. Histopathological examination coupled with immunohistochemistry
confirmed the diagnosis of Sinonasal Hemangiopericytoma. This case report stresses upon various
differential diagnosis of sinonasal swellings and the importance of considering long term follow up of
Sinonasal Hemagiopericytoma.
