title: Cholecystitis caused by hemocholecyst from underlying malignancy.
abstract: Massive hemobilia is a well recognized clinical entity, particularly when it presents with jaundice, GI bleeding, and biliary pain. However, occult hemobilia is more difficult to diagnose and has seldom been reported because of its clinically silent nature. In fact, this is usually overlooked until complications arise. Hemocholecyst or clot within the gallbladder may rarely occur in this setting, leading to cystic duct obstruction and cholecystitis. Most previous reports describe cholecystitis resulting from hemocholecyst after iatrogenic trauma. We describe two cases in which hemocholecyst occurred from underlying malignancies, both resulting in cholecystitis (acute or chronic).
