A rare renal tumor arising from proximal tubular epithelial cells of the renal cortex, characterized histologically by malignant epithelial cells with typical clear cytoplasm in conventional staining methods due to a high glycogen and lipid content, featuring a nested growth pattern. Clinically it may present with hematuria, flank pain, anemia or, less commonly, a palpable abdominal mass.
