Gastric metastasis from ovarian carcinoma: a case report and literature review.

An isolated parenchymal gastric metastasis from ovarian carcinoma without any other sites of recurrence is extremely rare. Only two cases have been reported, both of which were symptomatic. We herein report such a case without any symptoms. A 61-year-old woman presented with a high cancer antigen-125 level without any other clinical manifestation. A subsequent ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography scan revealed a submucosal mass with hypermetabolism of ¹⁸F-FDG (standardized uptake value: 5.36) in the gastric antrum. The final pathology after gastric antrectomy showed a metastatic gastric tumor from a primary ovarian carcinoma. We also performed an extensive literature review about gastric metastasis from ovarian carcinoma published until recently, and this is the first case of an isolated parenchymal gastric metastasis from ovarian carcinoma without any symptoms.
