Primary carcinoma of stomach with uterine metastasis

Curettings from a 42-year-old woman who suffered from heartburn, weight loss and irregular vaginal bleeding showed apparently metastatic mucoid adenocarcinoma in the endocervix. The primary site of tumour was not evident. At laparotomy a gastric adenocarcinoma was found and total hysterectomy with bilateral salpingo-oophorectomy and partial gastrectomy were performed. Histological examination showed a diffuse mucoid adenocarcinoma of stomach with metastases to lymph nodes, uterine body, cervix and one ovary. The literature about metastasis of extragenital cancer to the uterus is reviewed and possible mechanisms are discussed.
