The first reported case of Noonan syndrome complicated with hepatocellular carcinoma.

Noonan syndrome is a genetic multisystem disorder and is associated with mutation of genes encoding the proteins in the RAS-MAPK pathway. We reported the first case of Noonan syndrome complicated with hepatocellular carcinoma.

An autopsy case of primary jejunal pouch cancer which protruded from the abdominal wall 14 years after total gastrectomy for gastric cancer.

Adenocarcinoma which develops in the jejunal pouch has rarely been reported, but most of such cases tend to be a recurrence of primary cancer due to the presence of residual or disseminated cancer cells. Primary jejunal pouch cancer is extremely rare. We experienced an autopsy case of primary jejunal pouch cancer which occurred 14 years after proximal gastrectomy for gastric cancer.
