Popis: | Pedunculated hepatocellular carcinoma (HCC) or extrahepatic growth of HC C is an uncommon but not rare pathological form, but its genesis is unknown. Right-sided adrenal metastases of HCC that were abutting on or about to fuse with the right hepatic lobe were resected in three patients. The masses seemed to have originated in the para-adrenal tissue, leaving the adrenal gland intact. They were partially supplied by the hepatic artery as well as by the suprarenal artery. Four cases of autopsied pedunculated HCC of the right lobe were also studied. The mass was protruding caudad from the noncancerous parenchyma of the right lobe. Postmortem angiography carried out on one liver showed that only a small portion of the mass toward the liver was supplied from the hepatic artery. These observations suggest that some, perhaps most, of the right-sided pedunculated HCCs represent fusion of the right lobe and para-adrenal or adrenal metastatic HCC. This phenomenon may be explained by possible transport of cancer cells toward the right adrenal gland through the so-called adrenohepatic fusion, a relatively common anatomical change in advanced age. |
