Microcysts within early-stage autosomal dominant polycystic kidney disease. Representative images of kidney sections from patients with early-stage autosomal dominant polycystic kidney disease (A, K215; B and C, K001; D, K106). Sections stained by (A) hematoxylin and eosin and (B–D) periodic acid-Schiff methods showed multiple cysts measuring less than 1 mm in diameter within otherwise relatively preserved parenchyma. The small cysts were present within both (A, C, and D) the cortex and (B) the medulla. Scale bar, 200 µm.
