Abstract:
Solitary fibrous tumours (SFT) are mesenchymal tumours that usually arise from the pleura. Renal SFT are exceptional (9 cases reported in the literature). The authors report a new case discovered during assessment of HT and treated by radical right nephrectomy. The histological appearance is characteristic: a tumour with a fibrous centre, composed of a monomorphic proliferation of spindle cells, with positive CD 34, CD 99, and bcl 2 labelling. The prognosis after complete resection is generally favourable.
