Gallbladder cancer prep back

Gallbladder adenocarcinoma is a type of extrahepatic cholangiocellular carcinoma. The cell type of origin is the cholangiocyte, the cell type that lines the bile ducts.

On this preparation is there actually no macroscopic sign of tumor on the gallbladder itself, however because we can see metastases on the liver can we know that there is actually a gallbladder tumor here.
