Upper Gastrointestinal Manifestations of Crohn's Disease: Differential Diagnosis and Treatment of an Uncommon Presentation of Crohn's Disease.

Esophagogastroduodenoileal involvement of Crohn's disease (CD) is uncommon; less than 5% of adult patients will suffer from this condition, although this diagnosis is likely underestimated given the lack of routine evaluation of the upper gastrointestinal tract in the absence of symptoms. An interesting differential, including sarcoidosis, eosinophilic gastroenteritis, tuberculosis, and Brunner's gland hyperplasia, should be considered. The consequences of this diagnosis can have profound impacts on the military career of a soldier. Learning objectives of this case report include workup, differential, diagnosis, and treatment of esophagogastroduodenoileal involvement of CD, as well as discussing the psychological effects of this diagnosis and impact on an individual's military career.
