Phalangeal and Metacarpal Metastases from Clear Cell Sarcoma of the Kidney: A Case Report

ABSTRACT

Clear cell sarcoma of the kidney(CCSK) is rare, and was previously thought to be a variant of Wilms' tumor. Incontrast to patients with Wilms' tumor, bone metastasis is common in patients with CCSK, in which because of itsskeletal metastasis, prognosis is worse. We describe the radiographic, MR imaging, and bone scintigraphy findings,and include a review of the literature.
