Upper Gastrointestinal Bleeding due to Metastatic Endometrial Adenocarcinoma.ACG Case Rep J 2019; 6(7):e00138AC
Upper gastrointestinal bleeding (UGIB) is a life-threatening complication and a commonly encountered diagnosis requiring hospitalization. It is defined as bleeding proximal to the ligament of Treitz with the most common cause being peptic ulcer disease. There are multiple causes of UGIB and each of them presents its own unique diagnostic and management challenges. We present a rare case of UGIB due to endometrial adenocarcinoma metastatic to the third part of the duodenum. Most common sites of metastasis from endometrial adenocarcinoma are pelvic and paraaortic lymph nodes, and it is very rare for endometrial cancer to metastasize in gastrointestinal tract and then present as UGIB.
