Figure 5. Morphological aspects of human clear cell tubules (CCT) and advanced lesions.
Glycogenotic CCT (A. arrowhead) at the related glomerulus with its vas afferens and the transition (B. arrows) of distal tubule epithelial cells to glycogen storing CCT and multiple CCT lesions in the renal cortex (C. arrowheads) could be detected in the nephrectomy specimens. The glycogenotic tubules also form cell clusters near the related glomerulus D. or almost 1 mm large nodules. Nodular lesions with a basophilic (E. larger magnification of the square box) or acidophilic (F. larger magnification of the square box) cytoplasm, enlargement of nuclei and prominent nucleoli represent advanced lesions. Length of the lower edge: A, B 0.3 mm, C 1.67, D, E 1 mm, F, G 0.6 mm.
