A 32-year-old female presented with a right ovarian mass, and the unilateral oophorectomy specimen revealed adenocarcinoma with signet-ring cells histology consistent with a Krukenberg tumor. The high-grade gastric primary adenocarcinoma was later identified, but by this time a viable 7-week fetus and left ovarian Krukenberg tumor were present. Second trimester palliative oophorectomy and partial gastrectomy were performed. The patient delivered a healthy infant by cesarean section and is now 36 months after the initial diagnosis of metastatic gastric carcinoma and remains asymptomatic and free of disease. The unexpectedly favorable clinical outcome suggests that a patient may benefit from resection of gastric adenocarcinoma metastatic to ovary when other sites of metastatic disease are not evident.
