Pure squamous cell carcinoma of the gallbladder locally invading the liver and abdominal cavity: A case report and review of the literature

Table 1 Timeline

Time	Measure	Results
November 8, 2017	Abdominal ultrasonography	A 5.8 cm × 4.5 cm heterogeneous mass localized in both the gallbladder and liver and a gallbladder with remarkably thickened wall, indicating a malignancy
November 15, 2017	CT and contrast-enhanced CT	Gallbladder carcinoma infiltrating the adjacent liver, with enlarged retroperitoneal lymph nodes
November 22, 2017	Radical cholecystectomy	The gallbladder adhered tightly to the greater omentum. Neoplastic entities were present at the bottom of the gallbladder, which had invaded the V hepatic segments of the liver
November 23, 2017	Pathological findings	A moderately differentiated SCC
November 24, 2017	Immunohistochemistry	A moderately differentiated SCC
April 15, 2018	Abdominal ultrasonography	A space-occupying lesion in the right posterior aspect of the first hepatic portal region, which was considered as cancer metastasis
April 16, 2018	CT and magnetic resonance cholangiopancreatography	Postoperative changes in gallbladder carcinoma and multiple metastases in the liver and abdominal cavity

CT: Computed tomography; SCC: Squamous cell carcinoma.
