Paravesical hemangiopericytoma. Apropos of a case

Paravesical hemangiopericytoma is a vascular tumour that develops at the expense of the pericyts surrounding the blood capillaries. Its dim prognosis relates to its high potential of malignancy. With respect to the first case examined at the Dakar C.H.U. (the 10th case world wide), a literature review has been done. The diagnosis is based on histology while arteriography provides guiding elements. This particular case strikes especially the young individual, with no preference for a given sex. Therapy-wise, radiotherapy seems efficient. But, surgery remains, at the moment, the choice treatment of paravesical hamangiopericytoma. It consists of a large exeresis associated with radiotherapy. Chemotherapy still hold a limited place within the therapeutic arsenal against paravesical hemangiopericytoma.
