Upper Gastrointestinal Bleeding Due to Metastatic Lung Adenocarcinoma in the Stomach and Duodenum.

There are very few reports of bloodborne metastasis of lung adenocarcinoma to the gastrointestinal tract, primarily due to poor prognosis and short survival rate of metastasized carcinoma. We present a case of a 79-year-old man with a medical history of lung adenocarcinoma, who presented with complaints of weakness and melena for 1 week. He had symptomatic anemia, for which he was transfused with blood.

A Common Infection in a Highly Atypical Patient: Hematochezia From a Cytomegalovirus Colonic Ulcer in a Young and Healthy Immunocompetent Patient.

Gastrointestinal (GI) cytomegalovirus (CMV) infections are far more common in immunocompromised as opposed to immunocompetent patients. Immunocompetent patients who develop GI tract CMV infections are typically older with medical comorbidities. As such, descriptions of GI CMV infections in younger immunocompetent patients are lacking.
