title: [Primary metastatic choriocarcinoma of the stomach].
abstract: Report an a post-mortem examination of a pure primary metastasizing chorion carcinoma of the stomach in a 66-year-old female patient. Referring to literature the formal pathogenesis and differential-diagnostic aspects are discussed. Due to the frequent combination with an adenocarcinoma the chorion carcinoma of the stomach is regarded above all as the result of a back-differentiation with realization of extraembryonic structures. But apart from this also a direct development from the HCG-producing cells of the gastric mucous membrane is supposed.
