An autopsy case of a rare primary tumor in a 76-year-old man is described. The tumor is histologically comprised of rhabdomyoblasts massively infiltrating without any epithelial elements referable to be as hepatoma. There was no evidence that regarded the hepatic tumor as metastatic secondary tumor in histological examination of other organs. Furthermore, interesting was the production of alpha-fetoprotein from the tumor cells that was detected by immunofluorescent antibody technique. Review of the literature on primary liver rhabdomyosarcomas or adult hepatoblastomas shows no similar case. ACTA PATH. JAP. 29: 485-491, 1979.

A dry powder of betel nuts, piper betel leaves and lime was administered to rats. Epidermal thickening was frequently observed in the upper digestive tracts of rats in groups fed the betel nut diet mixed with lime and the betel leaves diet, and a forestomach papilloma was seen in 1 rat given betel leaves diet. These epidermal changes were scarcely seen in rats given either betel nut or normal diet alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
