Clear cell sarcoma of the kidney: A review

Clear cell sarcoma of the kidney (CCSK) is a rare renal tumour that is observed most often in children under 3 years of age. Only a few large series of CCSK have been reported and patients with CCSK are often included among patients with other types of childhood renal tumours. The purpose of this paper is to review the published series and case reports of CCSK and to create an up-to-date overview of clinical and histological features, genetics, treatment, and outcome.
