title: Advocacy for renal biopsy based on two cases of mixed epithelial and stromal tumour.
abstract: We report 2 cases of mixed epithelial and stromal tumours revealed by flank pain in a 56-year-old woman and by a renal biopsy in another asymptomatic woman. A greater awareness among urologists and radiologists of the features of mixed epithelial and stromal tumours could help evoke this diagnosis preoperatively leading to needle biopsy and to the most appropriate type of renal surgery.
