Actinomyces Infection Mimicking Esophageal Cancer.

Actinomycosis is a bacterial infection, which rarely affects the esophagus. Our patient presented with persistent acute blood loss anemia and epigastric pain despite previously negative upper endoscopy. He underwent repeat endoscopy a few months later showing what was thought to be malignant esophageal cancer at the gastroesophageal junction; however, the biopsy report revealed chronic inflammation with actinomycosis.
