Malignant pleural mesothelioma, a rare, aggressive cancer primarily associated with asbestos exposure, is characterised by poor prognosis and limited treatment options. Distant metastases are uncommon, and peritoneal involvement is rare, while metastasis to the gallbladder is extremely unusual. We report the case of a patient with malignant pleural mesothelioma undergoing immunotherapy with nivolumab and ipilimumab, who developed recurrent acute cholecystitis. Imaging revealed features of acute cholecystitis with gallstones. She eventually underwent a laparoscopic cholecystectomy because immunotherapy could not be continued in the presence of infection. Histopathological and immunohistochemical analysis confirmed metastatic epithelioid mesothelioma. The gallbladder metastasis was likely haematogenous or from peritoneal seeding, rather than direct spread. This case underscores the importance of a high index of suspicion when evaluating atypical presentations of mesothelioma, particularly in the context of immunotherapy.
恶性胸膜间皮瘤是一种罕见的侵袭性癌症,主要与接触石棉有关,其特点是预后差且治疗选择有限。远处转移不常见,腹膜受累罕见,而转移至胆囊极为罕见。我们报告一例接受纳武单抗和伊匹单抗免疫治疗的恶性胸膜间皮瘤患者,该患者出现复发性急性胆囊炎。影像学检查显示有胆结石伴急性胆囊炎的特征。由于感染存在无法继续免疫治疗,她最终接受了腹腔镜胆囊切除术。组织病理学和免疫组织化学分析证实为转移性上皮样间皮瘤。胆囊转移可能是血行转移或腹膜播散,而非直接蔓延。该病例强调了在评估间皮瘤的非典型表现时保持高度怀疑的重要性,尤其是在免疫治疗背景下。
