Glomangiopericytoma/sinonasal type
hemangiopericytoma is a rare sinonasal
neoplasm arising from the
pericytes surrounding
capillaries and accounts for less than 0.5% of all sinonasal
tumors. This
tumor differs from conventional soft
tissue hemangiopericytoma in
location,
biologic behaviour and histologic features. Glomangiopericytoma is a borderline low
malignancy tumor with a good
prognosis after complete surgical resection. We
report a case of 60-year-old
woman who presented with progressive
nasal obstruction and frequent
nasal bleeding and was diagnosed as glomangiopericytoma on histopathological and
immunohistochemistry findings. Histological characteristics,
differential diagnosis and
prognosis of this
tumor are discussed in this article. This case has been reported because of its rarity and an array of
differential diagnosis.
