Taenia in the Gastrointestinal Tract

Abstract

A healthy 60-year-old woman presented with hematemesis and melena, which she had had for 1 day. Her physical examination was unremarkable, as were the results of routine blood tests. On upper gastroduodenal endoscopy, a tapeworm was seen, along with multiple erosions and active bleeding from ulcers in the stomach and duodenum. She did not use nonsteroidal antiinflammatory drugs, and Helicobacter pylori was not found. After treatment with praziquantel and a proton-pump inhibitor, the bleeding resolved. One year later, she presented with intermittent epigastric pain, which she reported having had for several months. Again, a tapeworm was seen on upper gastroduodenal . . .
