Angiotensinogen-producing hepatocellular carcinoma.

Angiotensinogen-producing hepatocellular carcinoma.

This paper describes the first case of an angiotensinogen-producing tumor. The tumor obtained from a hypertensive patient was examined for its renin and angiotensinogen contents. Renin activity was undetectable; however, the angiotensinogen level was extremely high compared with the levels in the tissue surrounding the hepatoma. The presence of angiotensinogen immunoreactivity in the tumor cell...

Hepatocellular Carcinoma in Sheep

Interleukin-8 Producing Hepatocellular Carcinoma with Pyrexia

We discuss a patient who had poorly differentiated HCC with pyrexia and high CRP in laboratory data, which are not commonly observed in the usual HCC. A 50-year-old man with a history of liver dysfunction was admitted with a chief complaint of a prolonged fever and general fatigue. Preoperative diagnosis was HCC with portal vein tumor thrombus. Posterior segmentectomy of the liver and thrombect...

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

Alpha-fetoprotein-producing esophageal adenocarcinoma: a mimicker of hepatocellular carcinoma.

Alpha-fetoprotein (AFP)-producing esophageal adenocarcinoma (EAC) is a rare occurrence. Elevation of serum AFP is commonly associated with hepatocellular carcinoma and yolk sac tumors, but rarely with esophageal carcinoma. Here, we report a rare case of AFP-producing EAC. A 51-year-old man presented with two weeks of acid reflux and a 35-lb weight loss. Laboratory data were notable for transami...
