Abstract:
Two cases of testicular metastases of a clear cell renal cell carcinoma sharing a very similar ultrasonographic pattern are reported. The observed pattern - masses containing multiple tiny cyst-like areas - is very similar to that of a previously described ovarian metastasis of clear cell renal parenchymal tumor and can be explained by histopathologic features. Despite the small number of cases, this ultrasonographic pattern of testicular mass may be specific for metastasis of clear cell renal cell carcinoma origin.

Metastasis
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Correlation
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:
Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
