We report a unique case of a 50-year-old female who presented with acute cholecystitis due to massive intracholecystic haemorrhage. A 17-mm pedunculated gallbladder polyp had been identified, but the patient opted for observation. Three weeks later, she presented to the emergency department with a chief complaint of epigastric pain. Computed tomography showed a distended gallbladder filled with hyperdense material, and magnetic resonance imaging confirmed a haematoma. Semi-urgent cholecystectomy was performed on the third hospital day. Pathological examination of the resected specimen revealed that a pyloric gland adenoma, which was positive for MUC6 and MUC5AC, had detached from its mucosal stalk, leading to significant hemorrhage. Although the primary indication for resecting large gallbladder polyps (\u226510\u00a0mm) is malignancy risk, this case suggests that the risk of acute haemorrhagic complications from tumour detachment should also be recognized as a strong rationale for surgical intervention.<\/jats:p>","DOI":"10.1093\/jscr\/rjag328","type":"journal-article","created":{"date-parts":[[2026,4,14]],"date-time":"2026-04-14T11:28:11Z","timestamp":1776166091000},"source":"Crossref","is-referenced-by-count":0,"title":["A case of gallbladder adenoma causing gallbladder haemorrhage"],"prefix":"10.1093","volume":"2026","author":[{"given":"Takumi","family":"Yokoyama","sequence":"first","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenta","family":"Sui","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shintaro","family":"Okawa","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumiaki","family":"Mukohara","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3810-3488","authenticated-orcid":false,"given":"Kazuma","family":"Iwata","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shimpei","family":"Tsudaka","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuta","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroki","family":"Otani","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norimitsu","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaaki","family":"Yano","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryuichiro","family":"Ohashi","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological and General Surgery, Kagawa Prefectural Central Hospital , 1-2-1 Asahi-machi, Takamatsu, Kagawa 760-8557 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"2026043018592094500_ref1","doi-asserted-by":"publisher","first-page":"790","DOI":"10.1097\/00000658-195005000-00018","article-title":"Biliary tract hemorrhage;
