Hemorrhagic acalculous cholecystitis: an unusual location of uremic bleeding.

Hemorrhagic acalculous cholecystitis is a rare but potentially fatal disease. An increased bleeding tendency is present in both acute and chronic renal failure with impaired platelet function. We herein present a case of hemorrhagic acalculous cholecystitis in a hemodialysis patient who suffered from acute abdomen and upper gastrointestinal bleeding. The pathogenesis may have been associated with ischemia and reperfusion injury, eventually leading to necrosis of the gallbladder wall. Abdominal ultrasound can aid in diagnosis. Biliary colic, jaundice, and melena are the typical symptoms of hemorrhagic cholecystitis, particularly in a patient with unexplained gastrointestinal bleeding.
