CLINICAL CASE OF COMPLEX RADICAL TREATMENT OF METASTATIC PROGRESSION TO RARE SITE OF PRIMARY ORGAN CONFINED CHROMOPHOBE RENAL CELL CARCINOMA TREATED WITH LAPAROSCOPIC PARTIAL NEPHRECTOMY.

We present a case of stage I chromophobe renal cell carcinoma, which initially was treated with laparoscopic partial nephrectomy, and four years later progressed to multifocal metastatic nodules in the perirenal adipose capsule without local recurrence in the kidney itself. The curative approach included the surgical complete removal of perirenal adipose tissue with adjuvant pembrolizumab. We discuss the molecular and genetic peculiarities of chromophobe renal cell carcinoma as applied to the diagnosis and a rationale for adjuvant pembrolizumab.
