Successful surgical resection of ruptured cholangiolocellular carcinoma: A rare case of a primary hepatic tumor

Figure 1 Contrast enhanced computed tomography scan showed a tumor located in the right anterior compartment of the liver with extrahepatic hematoma. The tumors were hyperattenuating relative to the noncancerous liver parenchyma on arterial-phase (A) and hypo- or isoattenuating on delayed phase (B).

Figure 2 The axial T1-weighted gradient-echo image showed a hypointense mass in the right anterior segment of the liver (A), and the axial T2-weighted spin-echo image with fat suppression showed an isointense mass with a large central hyperintense area (B).

Figure 3 Histologically, the tumor was mainly composed of small, monotonous glands formed into antler-like anastomosing patterns, embedded in the fibrous stroma to various degrees of fibrous stroma and lacking mucin production. A: Macroscopically, an expanding tumor located in the right anterior compartment of the liver with extrahepatic hematoma with central necrosis; B: HE staining demonstrated the tumors mainly composed of small, monotonous glands and embedded in various degrees of fibrous stroma without mucin production.

Figure 4 Cholangiolocellular carcinoma cells were confirmed by positive staining for cytokeratin 19 (A) and membranous positive staining for epithelial membrane antigen (B).
