RIBEIRO, J. G. A. et al. Unilateral Renal Haemangiopericytoma: Report of a Rare Tumour. Int. J. Morphol. [online]. 2006, vol.24, n.2, pp.165-170. ISSN 0717-9502.

The pericytes are modified smooth muscle cells (SMCs) that surrounding capillaries and to change the diameter of vascular lumen. In this article we report a case of renal haemangiopericytoma. A 78-year-old woman was admitted with a complaint of abdominal pain. Ultrasonography revealed a solid injury in the third portion of the left kidney. Abdominal CT scan revealed a tumoral mass. Due the high index of suspicion of malignant neoplasia the patient was submitted to left radical nefrectomy. The histopathological evaluation confirmed haemangiopericytoma by immunohistochemistry. The patient fared well and was alive 5 years after radical nephrectomy
