Adult female with hematemesis-Dieulafoy lesion

A 40-year-old healthy woman presented to the emergency department with a complaint of intermittent hematemesis, despite the absence of usual factors associated with upper gastrointestinal bleeding (ie, nonsteroidal anti-inflammatory drugs, alcoholism, etc). The patient was diagnosed with a Dieulafoy lesion. This is an uncommon finding, which clinicians must be familiar with and maintain in the differential diagnosis because the consequences of this disease process are grave. It is vital to properly diagnose this condition and be familiar with the treatment.
