Dear Editor, We have carefully read the response from Val-Bernal et al.,[1] and we feel sorry for any inconvenience that we may have caused. The purpose of our study[2] was to deepen the rare histologic type of renal tumor which is the chromophobe renal cancer with sarcomatoid differentiation, its mode of presentation, imaging techniques, histopathological analysis, prognostic factors, and treatment. Because it is a subject discussed in the literature but with only a few patients described, as a visual way to simplify the low incidence of this pathology, we used the results published by Bian et al.[3] on a table and added our clinical cases. With this, we reflected on the most important prognostic factors, as described in the literature, and how they affected survival. It is unquestionable that those two cases cited in Val-Bernal et al. could have enriched this table, especially because of their detailed histopathological analysis. Akhtar et al.[4] presented a left renal tumor with anaplastic spindle cells with a high mitotic rate intermingled with poorly differentiated
