METASTATIC OVARIAN TUMOR DISCOVERED ACCIDENTALLY DURING CESAREAN SECTION IN A 34-YEAR-OLD WOMAN: A CASE REPORT.

Krukenberg tumor is a rare metastatic ovarian carcinoma usually occur in female between 30-40-year-old and rarely seen after menopause. Stomach is the most common primary site. Histopathological features of krukenberg tumors appears as diffuse stromal proliferation, mucus-production, and numerous signet-cells and these tumors spread mostly by lymphatic route. Treatment and prognostic factors are not well established. This study describes a 34 year old female with a unilateral ovarian mass discovered accidentally during cesarean section delivery and it was misdiagnosed as luteoma of pregnancy, but histopathological examination showed a diffuse infiltration of the ovary and omentum by malignant cells, some of which have signet ring morphology. These findings were not correlated with luteoma of pregnancy or any other types of primary ovarian tumors like primary surface epithelial tumor, sex cord stromal tumor or germ cell tumor. A panel of immunohistochemicalmarkers were ordered and the results were as follow: (negative CK7, AFP, and alpha inhibin, and positive EMA, CK20 and CDX-2). these findingswere diagnostic for metastatic adenocarcinoma either from the stomach or pancreas (krukenberg tumor). Two weeks later, the patient was evaluated and a large gastric tumor was found in her stomach and she underwent gastrectomy.
