Solitary lesions are commonly found in the liver and are primarily caused by <i>Echinococcus granulosus</i>. Other organs can be involved as well but to a lesser degree. This paper presents a rare manifestation of a hydatid liver cyst causing acute pancreatitis. <b>Case Presentation:</b> A 67-year-old female presented with right upper quadrant pain, nausea, and vomiting. She was found to have a large hepatic cystic echinococcosis occupying the right lobe of the liver with associated acute pancreatitis. After endoscopic retrograde cholangiopancreatography (ERCP), three small yellow membrane fragments-presumed to be daughter cyst membranes-were found obstructing the common bile duct at the ampulla of Vater. The patient underwent laparoscopic unroofing of the hepatic cystic echinococcosis and laparoscopic cholecystectomy with an uneventful postoperative course. <b>Clinical Discussion:</b> Treatment modalities for hepatic cystic echinococcosis depend on the size of the cyst, imaging findings, cyst activity status, and associated complications. In nonendemic countries, where demographic changes occur due to travel from endemic regions, a high index of suspicion is necessary for timely diagnosis. A laparoscopic approach was chosen for its benefits related to minimally invasive surgery. While laparoscopic management of hepatic cystic echinococcosis is well described, its use in cases complicated by acute pancreatitis remains infrequently reported. <b>Conclusion:</b> Cystic echinococcosis most commonly presents in the liver. When associated with acute pancreatitis, a combined approach involving albendazole, ERCP, and sphincterotomy is typically required, with surgical resection depending on cyst classification.</p>","PeriodicalId":45645,"journal":{"name":"Case Reports in Gastrointestinal Medicine","volume":"2025 ","pages":"1244948"},"PeriodicalIF":0.5,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12356676/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144875841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Case of Ventricular Arrhythmia in a Patient With HER2-Positive Gastric Cancer Receiving Trastuzumab.","authors":"Naoto Takahashi, Hitoshi Fujii, Tomohiro Iwasa, Yuka Koizumi, Yukihiro Minagawa, Chihiro Tono","doi":"10.1155/crgm/2752788","DOIUrl":"10.1155/crgm/2752788","url":null,"abstract":"<p><p><b>Background:</b> Human epidermal growth factor receptor 2 (HER2)-positive gastric cancer accounts for approximately 15% of gastric cancer cases. Trastuzumab (Trz), a monoclonal antibody targeting HER2, has been shown to improve overall survival when combined with chemotherapy. However, while Trz-induced cardiotoxicity (TIC) is a well-recognized adverse effect in breast cancer chemotherapy, reports on its occurrence in gastric cancer treatment remain limited. <b>Case Presentation:</b> An 80-year-old Japanese male with HER2-positive advanced gastric cancer (cStage III) developed ventricular arrhythmia and heart failure during postoperative chemotherapy with the Trz + SOX regimen (Trz, oxaliplatin, and TS-1). The patient initially underwent distal gastrectomy with D1+ lymphadenectomy for anemia and pyloric stenosis. Metastasis to the #8a lymph node (anterior superior lymph node of the common hepatic artery) and pancreatic invasion via lymph nodes were treated with two cycles of the Trz + SOX regimen, leading to a partial response. However, after the 11th cycle, he developed ventricular tachycardia and heart failure. Cardiac imaging and laboratory findings revealed no coronary artery disease or structural abnormalities, suggesting TIC as the underlying cause. Antiarrhythmic therapy with pharmacological agents led to symptom resolution, and no recurrence of arrhythmia or heart failure was observed. <b>Discussion:</b> This case highlights the potential cardiotoxicity associated with nonanthracycline-based Trz regimens for gastric cancer. Pathophysiologically, HER2 signaling inhibition in cardiomyocytes may impair stress responses and repair mechanisms. The patient's advanced age, history of hypertension and anemia, and cumulative exposure to chemotherapy may have contributed to increased cardiac vulnerability. Careful monitoring of cardiac function is essential in elderly and comorbid patients undergoing Trz-based therapy for gastric cancer to mitigate the risk of cardiotoxicity. <b>Conclusion:</b> Trz-based chemotherapy for HER2-positive gastric cancer, even without anthracyclines, may pose a risk of cardiotoxicity, particularly in elderly or comorbid patients. Further research is warranted to elucidate underlying mechanisms and optimize monitoring and prevention strategies in this population.</p>","PeriodicalId":45645,"journal":{"name":"Case Reports in Gastrointestinal Medicine","volume":"2025 ","pages":"2752788"},"PeriodicalIF":0.6,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12283206/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144691909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clear-cell variant of CCA is rare, with only nine documented cases worldwide. This case report describes a unique presentation of clear-cell intrahepatic (or peripheral) cholangiocarcinoma (ICC), highlighting its clinical course, histopathological features, and management. <b>Case Presentation:</b> A 56-year-old female with no significant medical history presented with postprandial right upper quadrant and epigastric pain. Following an initial diagnosis of gallbladder stones, laparoscopic cholecystectomy was performed. However, persistent epigastric pain, nausea, and vomiting led to further evaluation, revealing a 2.7 × 2.5 cm mass in the gallbladder bed compressing the common bile duct with associated intrahepatic biliary dilation. Endoscopic retrograde cholangiopancreatography confirmed the findings, and the patient underwent a left hemihepatectomy with radical choledectomy and biliary reconstruction. Histopathology demonstrated clear-cell ICC. Postoperatively, the patient received adjuvant chemotherapy and remained disease free at 14 months' follow-up. <b>Methods:</b> A systematic review and meta-analysis were conducted according to PRISMA guidelines and the Cochrane Handbook. A comprehensive search of PubMed and SCOPUS was performed without restrictions until December 2024 to identify case reports and case series of clear-cell CCA. Data on clinical presentation, diagnostic findings, treatment modalities, and outcomes were extracted and analyzed. The quality of included studies was assessed using the Joanna Briggs Institute critical appraisal tools. <b>Results:</b> The systematic review included 7 studies reporting 9 cases of clear-cell CCA.

Factors such as tumor size and the presence of metastasis influenced prognosis. <b>Conclusion:</b> Clear-cell CCA, though rare, should be considered in the differential diagnosis of biliary masses.
