Dual Pathology: A Case of Concurrent Lymphocytic Esophagitis and Crohn's Disease.

Crohn's disease (CD) is a chronic, systemic disease characterized by transmural inflammation of the gastrointestinal (GI) tract. Patients can present with a range of GI and extraintestinal features depending on the areas involved. Esophageal involvement can be a direct result of Crohn's or other co-existing diseases. Determining the cause of esophagitis in CD is important as it affects management and prognosis. Lymphocytic esophagitis (LE) is an example of a disease that can cause esophagitis on a background of CD. Patients presenting with the two conditions simultaneously are relatively rare. We present a case of LE and CD in a young male patient.
