The association of gastric cancer and pregnancy is rare. The cases reported by non-Japanese authors are unusual. Tumors tend to be in advanced stage when diagnosed since the symptoms of gastric cancer are easily presumed to be secondary to those of normal pregnancy. We report the case of a 43-year-old female with gastric carcinoma presenting as a Krukenberg's tumor in the eighth month of gestation. A healthy child was born and after delivery, partial gastrectomy was performed and adjuvant chemotherapy was administered. The patient died 12 months after diagnosis.
