Gallbladder sarcomatoid carcinoma: A case report and review of current literature

SummaryGallbladder sarcomatoid carcinoma is a rare neoplasm characterized by the simultaneous presence of malignant epithelial and mesenchymal components. There is little information about the clinical behavior and optimal treatment for these tumors. The current study examines the case of a 52-year-old female patient who presented with postprandial epigastric pain that had persisted for 1 year. A diagnosis of gallbladder sarcomatoid carcinoma was confirmed by pathology after radical resection. Peritoneal metastasis occurred 3 months later, and the patient died 6 months after diagnosis. This study found that the prognosis of gallbladder sarcomatoid carcinoma is poor even after curative resection and there is as yet no known effective adjuvant therapy.
