[A Resected Case of Adeno-Squamous Carcinoma of Gallbladder with Liver Invasions]

A patient was 70-year-old female. Because unknown fever following operation of left knee in December 20XX-1, abdominal simple CT was performed, diagnosed as cholecystitis and liver abscesses. However, her unknown fever did not improve with antibiotics therapy. Abdominal enhanced CT and MRI revealed to gallbladder cancer with liver invasion and metastases. These lesions were relatively localized in liver S4a/S5 and gallbladder, hepatoduodenal mesentery. Because unknown fever was exhausting, cholecystectomy, S4a+S5 hepatectomy with extrahepatic bile duct resection and lymph node dissemination were performed in January 20XX+1. In these pathological findings, there were moderate to poorly differentiated adenocarcinoma with squamous cell differentiation in almost area of gallbladder, diagnosed as adeno-squamous carcinoma with liver invasion and metastasis(pT3a[SI][H-inf], int, INF-β, ly1, v3, pn1, pN1, pM1, pStage ⅣB). One months after operation, abdominal CT revealed multiple liver metastatic recurrences. She died 7 months after operation. Although gallbladder adeno-squamous carcinoma has a poor prognosis, these many cases had a tendency to local infiltration accompanied with tumor fever. If curative resection might be obtained and the symptoms might be improved, aggressive resection should be performed.
