Carcinosarcoma Gallbladder: A Rare Variety of Gallbladder Malignancy

Gallbladder malignancy is frequently found in Indian population. Most of them are adenocarcinoma variety whereas carcinosarcoma variety is quite rare. It is typically characterised by presence of both epithelial and mesenchymal components. The prognosis of this variety is poorer because of its aggressive nature and delayed diagnosis. Here we report a case of Carcinosarcoma of Gallbladder (CSGB) in a 40-year-old lady presenting to us with features of acute cholecystitis and gallbladder mass. She was treated with radical cholecystectomy, bile duct excision and Roux-en-Y Hepaticojejunostomy (RYHJ). Histopathological examinations reveal pleomorphic spindle cells as well as epitheloid cell. In postoperative period she received adjuvant chemotherapy. Despite all these treatment she developed recurrence at seven months follow up.
