[An uncommon case of proximal Crohn's disease].

Crohn's disease (CD) is a chronic, inflammatory disorder that can involve any part of the gastrointestinal tract, from the mouth to the anus. Although CD mainly affects the terminal ileum and colon, the involvement of the upper gastrointestinal tract rarely occurs. Diagnosis is based on clinical, endoscopic and histological features. Treatment for CD of the upper gastrointestinal tract is similar to distal CD therapy. Corticosteroids added to proton pump inhibitors are usually used. The case of a 42-year-old female patient with CD located in the oesophagus, stomach and duodenum is presented. Among the complementary tests, an endoscopic evaluation of the upper gastrointestinal tract with biopsies was essential to support CD diagnosis.
