Abstract
Germ cell tumors are the most frequent neoplasia in young males. The aims of this study is to describe a case in which a postpuberal teratoma suffers a transformation to choriocarcinoma and metastasize to stomach. We have made a systematic review in PubMed and consensus documents to study this mismatch between the tumour, metastasis and the exception of gastric metastatic affectation. We describe three options to explain this discordance: a mixed germ cells tumour, a burned out tumour or a germ cells tumour derived from a malignant germ cell tumour precursor or different clonal strains. After made a thorough investigation we conclude that the most truly option is the last one as we extensive explain below. Once the gastric metastatic lesions are extremely rare and reach to <5%, but there are not conclusive assessments.
