Introduction: Krukenberg tumor is an ovarian tumor that originates from metastases from other organs such as the stomach, colorectal, pylorus, appendix, colorectal or breast. The tumor is characterized by mucin-rich signet-ring adenocarcinomas. Premenopausal women have a higher risk of Krukenberg tumor, where the median occurs at 48 years which the range of age is 27 - 65 years. This study aims to report the incidence of Krukenberg tumor found in a 36-year-old woman who had completed therapy at Margono Soekarjo Hospital.

Case Presentation: This case reports the occurence of Krukenberg's tumor found in 36-year-old woman with stomach's burning sensation and a mass located on the right and below Arcus Costae. The patient underwent metasectomy and biopsy. Histopathological examination showed that the caracteristics of the tumor originated from the stomach. The macroscopic examination findings were two pieces of tissue consisting a brownish white stomach tumor in size of 1x1x0.5cm and and a two lobes right ovarian tumor with 15.5x10x9cm. Microscopic findings of the stomach tumor  howed a group of malignant epithelial cells with round oval nuclei, moderately pleiomorphic, hyperchromatic, with intranuclear pseudo-inclusion infiltrating, forms papillary tubular structure that infiltrated the inflamed stroma. As for the ovarian tumor, it showed similiar malignant cells and forming tubular, papillary, and reticular structure, along with the signet ring cells deeply infiltrated the inflamed stroma. The patient then underwent 6 cycle chemotherapy and 20 cycles of radiotherapy, with several evaluations. This case had been observed for 12 months since the patient came to the hospital.

Conclusion: Krukenberg tumor is a rare ovarian tumor characterized by a poor prognosis. This case illustrates the finding of Krukenberg tumor with clinical features of the stomach. A combination of metastasectomy and chemotherapy can be performed to increase patient survival rates.
