Abstract
Described as a type of soft-tissue tumour with malignant potential, hemangiopericytoma originates at the level of the pericytes, cells located in the walls of the capillaries. Although the etiology is not completely elucidated, it seems that the genetic factor plays an important role in the appearance of this type of tumour. Several cases with autosomal recessive transmission have been described in the literature. It is a formation that can occur at any age, but is more common after the age of 40. In fact, following multiple scientific studies, it has been concluded that the average age of affected people is somewhere around 45 years, while the survival rate at 10 years is 70%. Several cases have also been described in childhood (the percentage of occurrence at this age is between 5 and 10%). The sex incidence is equal. In what follows, I thought of presenting the case of a 90-year-old male person, diagnosed with an infiltrative and vegetative tumour formation located in the cavum, which turned out to be, after the anatomopathological examination, a hemangiopericytoma.
