Nausea and vomiting are common sufferings of pregnant woman. No gynaecologist would consider carcinoma of the stomach as a probable differential diagnosis according the extremely rare probability of this disease during pregnancy. Consequently, a late diagnosis in pregnancy can result in spreading throughout the whole abdomen. In this advanced stage, it is only possible to recommend palliative care to the patient followed by short survival. Fetal metastasis is a rare entity, therefore caesarean section and chemotherapy should not be performed until fetal maturity. If vomiting and nausea are prolonged after the sixteenth week of pregnancy a malignant disease of the stomach should be excluded. Only in case of short delay between symptoms and diagnosis, the stomach cancer can be resected totally followed by a better overall survival of the patient.
