Scanning electron microscopy of polycystic liver disease.

Resected specimens of PCLD by laparoscopic fenestration surgery were evaluated by scanning electron microscopy. Epithelium lining the largest cyst (26 cm in size) showed prominent villous proliferation with positivity of Ki-67, while the epithelium of the small cyst (3 cm in size) showed slight proliferation (smooth) with small positivity of Ki-67.
