[Renal cell carcinoma secondary to tuberculous nephritis].

The combination of renal tuberculosis and renal cancer is rare. The authors report the case of a patient who was followed for multifocal pulmonary, hepatic and renal tuberculosis. The diagnosis of associated renal tumour was raised in the presence of suggestive radiological images. Tumourectomy was performed after tuberculostatic therapy, and histological examination revealed renal cell carcinoma associated with caseo-follicular tuberculous granulomas. The outcome was favourable after a follow-up of 2 years. The objective of this study is to analyse the pathogenesis, diagnostic features and treatment modalities of this exceptional combination.
