HIDALGO MENDEZ, Fernando. Retroperitoneal Hemangiopericytoma. Rev Clin Med Fam [online]. 2013, vol.6, n.2, pp.98-101. ISSN 2386-8201.  https://dx.doi.org/10.4321/S1699-695X2013000200003.

Hemangiopericytoma is a rare tumour of vascular origin derived from Zimmermann's pericytes. It represents approximately 1% of all  vascular  tumours. At the time of diagnosis, determining the malignant potential of this type of mass is usually controversial. Prognosis will be based on  histological patterns and the clinical course, with the appearance of local recurrences or distant metastases being the only definitive signs of malignancy. The case of a 61 year old patient with a very large retroperitoneal hemangiopericytoma serves to review clinical and pathological aspects, treatment and prognostic factors of this rare neoplasm.
