• canalicular cholestasis
  8 December 2004

  Canalicular cholestasis takes the form of bile plugs (bile thrombi) in dilated canaliculi.
  There is often brown or yellow pigment in nearby hepatocytes and Kupffer cells, but the distinction of this pigment from others such as lipofuscin and ceroid is not a serious practical problem; this is because the presence of bile in the canaliculi makes the diagnosis of cholestasis obvious.
  In general, cholestasis should only be diagnosed with great caution in the absence of bile plugs in (...)
