Clear cell sarcoma of the kidney: A clinicopathologic study of 21 patients with long-term follow-up evaluation

Role of fine needle aspiration cytology in the management of pediatric renal tumors

“…[8] CCSK, also known as bone metastasis tumor, is not uncommon and forms around 5% of pediatric renal tumors. [15,16] We found 8 of 119 aspirates (6.72%) to be CCSK; however, this high incidence was mainly among late stage inoperable patients. [8] CCSK has a poor outcome compared to WT [16] and requires a separate chemotherapy regimen incorporating doxorubicin to which it is sensitive.…”

Clear cell sarcoma of kidney in an adult: an extremely rare case

“…Clear cell sarcoma is a very malignant tumor with a high tendency for relapse and a propensity for skeletal metastases particularly skull. 4 Metastases also occur to regional lymphnodes, brain, lung, and liver. These metastases tend to develop after long intervals following the removal of the primary tumor (5 years or more).…”

Fine Needle Aspiration Biopsy Diagnosis of Renal Masses in Children: A Brief Review

“…Several excellent studies describing the histologic features of this neoplasm have been published in the literature. 13,[19][20][21] A large number of overlapping histologic patterns has been recognized. Clear cell pattern is the most common.…”
