History
Manifestations in patients with clear cell sarcoma of the kidney (CCSK) are similar to those in patients with Wilms tumor. Patients present with an abdominal mass (see the image below), which is usually identified by a caregiver or family relative who has not seen the child in some time.
Large right-sided heterogeneous renal mass in a 9-month-old infant. Biopsy findings were consistent with clear cell sarcoma of the kidney. Often, abdominal swelling or the presence of an abdominal mass is noticed by a parent while bathing or dressing the child. Abdominal pain, gross hematuria, fever, and hypertension are other frequent findings.
Physical
Physical findings include a large palpable unilateral abdominal mass. Patients may have accompanying findings, such as hypertension and/or hematuria (gross or microscopic), depending on the size of the tumor. Extrarenal tumors with histologic features identical to those of clear cell sarcoma of the kidney have been reported.
Causes
The histogenesis of clear cell sarcoma of the kidney is unknown and appears to be unrelated to Wilms tumor. No specific chromosomal translocation has been associated with clear cell sarcoma of the kidney; a finding that generally indicates a normal karyotype.[9]
The origin of clear cell sarcoma of the kidney has not been established. Dysregulation of the EGFR pathway has been observed at multiple levels in clear cell sarcoma of the kidney. The proto-oncogene c-kit is overexpressed in clear cell sarcoma of the kidney but is not accompanied by gene amplification or activating mutations. The t(10;17)(q22;p13) and deletion 14q have been described. Cells that have been suggested as the origin for clear cell sarcoma of the kidney include renomedullary interstitial cells, nonorgan specific mesenchymal cells, blastemal cap cells, primitive mesenchymal cells, and the cells that form the lower limbs of S-bodies. Cutcliffe et al have suggested that the cell of origin is within a renal mesenchymal cell that possesses neural markers.[10]
