title: Carcinoma gall bladder presenting as hemobilia.
abstract: A 60-year-old man presented with recurrent bouts of melena, requiring multiple transfusions. Upper GI endoscopic evaluation demonstrated fresh bleeding from the ampulla of Vater. Ultrasonography and CT scan suggested a gall bladder mass without evidence of metastases. Laparotomy confirmed a mass confined to the lumen of the gall bladder. The patient underwent cholecystectomy. Histological examination showed papillary adenocarcinoma of the gall bladder extending up to the muscularis propria.
