[Gastric adenoacanthoma. Report of a case and review of the literature].
Squamous and adenosquamous carcinomas of the stomach are extremely rare, having a reported incidence of between 0.04 and 0.7%. Up to date, only two cases have been published in argentine literature by W. G. Lange, 1955. This is the reason of presenting this 68 year old woman, whose disease begins as an inflammatory process of the gallbladder and pancreas, later studies showed that it was an adenosquamous carcinoma of the stomach. Its pathogenesis is most probably from an area of preexisting squamous metaplasia, but the origin from a totipotencial cell (stem cell), from an area of ectopic stratified squamous epithelium or by squamous metaplasis developing within a preexisting adenocarcinoma has not as yet been established.
