Contrast-enhanced computed tomography showing an irregular, well-defined, poorly enhanced tumor, measuring approximately 70 mm in diameter, in the right lobe of the liver.

(A and B) Esophagogastroduodenoscopy shows a single, white-toned, hard tumor of 5 mm diameter, which is shaped like a submucosal tumor (SMT), 30 cm from the incisor. (C and D) Atypical blood vessels of different caliber are seen on top of the tumor in a magnified observation using blue laser imaging.
Figure 4.
Figure 4.
Histopathological section shows an invasive, poorly differentiated adenocarcinoma just below the esophageal squamous epithelium (positive staining for cytokeratin [CK] 7 and CK 19, and negative for CK 20, which is consistent with cholangiocarcinoma). In addition, floating cancer follicles in the lymphatic vessels, which stained positive for D2-40, were suggestive of lymphatic metastasis.
