Intra-Atrial Tumor Embolus in Hepatocellular Carcinoma

A case of hepatocellular carcinoma with a massive tumor embolus in the right atrium is reported. Although hepatocellular carcinoma often invades into portal and hepatic vein and may extend into the inferior vena cava, it is rare that the tumor grows out to fill the right atrium. The literature on the intracardiac metastasis of hepatocellular carcinoma as well as other carcinomas is reviewed

Gigantic Immature Sacrococcygeal Teratoma in an Abortus

An autopsy case of giant immature sacroccygeal teratomaseen in an abortus is presented here. It was unusual for such a teratomato weigh more than the fetus. Histology of the tumor was characterizedby a large amount of immature and neuroepithelial elements in additionto other endodermal and mesodermal elements. Although α-fetoproteinwas high in the amniotic fluid, no germ cells were identified. No invasionor metastasis was noted. We considered the bad prognosis in fetal casesmay be due not to the amount of immature tissue but rather to theobstetric complication resulting from the large tumor size
