Abstract
Background. Undifferentiated gallbladder carcinoma is a rare type of cancer with poor prognosis, due to the absence of specific clinical manifestations, and the final diagnosis depends on pathological and immunohistochemical examinations. However, only a few reports of SMARCA4-deficient undifferentiated gallbladder tumor have been published to date. Therefore, we report the diagnosis and treatment of an undifferentiated gallbladder carcinoma with SMARCA4 deficiency. Case Presentation. A 65-year-old woman with undifferentiated gallbladder carcinoma was treated using traditional Chinese medicine and underwent palliative surgery in our hospital. The postoperative pathology showed SMARCA4-deficient undifferentiated gallbladder carcinoma with metastasis to the abdominal lymph nodes. Conclusions. This case report contributes to the limited literature regarding undifferentiated carcinoma without SMARCA4 in the gallbladder.
