Carcinoma renal de células claras localmente avanzado con tuberculosis renal asociada

The association of renal cell carcinoma (RCC) and renal tuberculosis (TB) is uncommon. Whereas the incidental discovery of RCC in tuberculous kidneys is well described, the discovery of tuberculous lesions after radical nephrectomy for cancer is exceptional. The aim of this article was to report a case of locally advanced clear cell RCC whose histologic study revealed associated TB. There are very few published cases of kidney cancer and TB. A case of squamous cell carcinoma of the renal pelvis in a kidney with TB and a case of renal adenocarcinoma and TB have been reported. The present case describes locally advanced RCC with high tumor burden and retroperitoneal adenopathy that, before surgery, suggested metastatic disease to the lymph nodes. However, only histopathologic changes due to TB were found. No clinical or pathologic correlation has been found between these 2 entities, and clinical studies on the subject are lacking.
