Abstract

<p>A 34-year-old woman presented to a clinic with epigastralgia and was diagnosed with type 3 gastric cancer. Cystic lesions in both ovaries were detected preoperatively, which were diagnosed as benign tumors. There was no peritoneal dissemination in staging laparoscopy. After laparoscopic enucleation of the right ovarian tumor, open distal gastrectomy with D2 lymph node dissection was performed. Histopathology revealed stage IIB gastric cancer (por, T4a(se), Ly1a, V1a, N0, M0) and a mature cystic teratoma in the right ovary. After adjuvant chemotherapy, the right ovary began to grow, which appeared to be ovarian metastasis of gastric cancer or malignant conversion of the teratoma. Fourteen months after the gastric resection, bilateral oophorectomy was performed. Histopathology revealed the right ovarian tumor to be ovarian metastasis of gastric cancer, so-called “Krukenberg tumor”. She has been well without any recurrence for 5 years after gastrectomy or 4 years after oophorectomy. Although gastric cancer without accompanying lymph node metastasis nor peritoneal dissemination rarely metastasizes to the ovary, resection of the ovaries should be considered if they are growing in size. In addition, MRI may be useful in evaluating ovarian lesions which have existed there before the surgery during the follow-up.</p>
