An Unusual Cause of Hematemesis in a Patient Previously Treated for Cholangiocarcinoma

A 75-year-old woman presented with hematemesis and a history of perihilar cholangiocarcinoma treated with left lobectomy, caudate lobectomy, and Roux-en-Y hepaticojejunostomy. Esophagogastroduodenoscopy revealed a 3×3-cm polypoid lesion accompanied by active bleeding. Biopsy revealed adenocarcinoma, favoring metastasis over primary gastric cancer, considering the patient's medical history and previous endoscopic evaluations. Despite endoscopic hemostasis, anemia persisted, prompting laparoscopic wedge resection of the gastric mass. Here, we present a rare case of gastric metastasis from cholangiocarcinoma, underscoring the unusual presentation of upper gastrointestinal bleeding caused by a gastric tumor in a patient previously treated for cholangiocarcinoma.
