Metastasis of a maternal neoplasm to the products of conception is extremely rare. About 50% of the reported cases were not examined grossly or had no grossly visible tumor deposit. A case of placental micrometastasis of gastric adenocarcinoma in a 28-year-old woman is presented. Artificial termination was performed in 22 weeks of gestation and a female fetus weighing 440 gm was delivered. The placenta weighed 220 gm and was grossly normal. Microscopic examination revealed a small number of micrometastasis scattered in the intervillous space.
