Metastatic gastric adenocarcinoma to the uterine cervix—a case report and review of the literature

Abstract

Abstract Background Poorly differentiated diffuse-type gastric adenocarcinoma often presents at an advanced stage. While gastric cancer typically metastasizes to the liver, lung and bone, metastasis to the uterine cervix is extremely rare. To our knowledge, less than forty cases have been described in the medical literature. Case presentation We report a case of a 47-year-old woman who presented to us with symptomatic uterine leiomyomas and subsequently underwent a successful total laparoscopic hysterectomy and bilateral salpingo-oophorectomy. The diagnosis of metastatic cancer involving the cervix was established incidentally on histopathology, which demonstrated atypical signet ring cells in the lymphovascular spaces of the cervix. Further investigations for a primary malignancy revealed a poorly differentiated diffuse-type gastric adenocarcinoma. Conclusion Gastric cancer involving the uterine cervix is rare and associated with a poor prognosis. When presented with isolated cervical metastases, the gastrointestinal tract should be considered as a possible primary source. Due to the limited publications on this clinical entity, we expect to raise awareness and study this unique manifestation of gastric cancer by presenting our case.
