Lupus enteritis masquerading as Crohn’s disease

Systemic lupus erythematosus is an autoimmune disease which can affect multiple organs, resulting in significant mortality and morbidity. Lupus enteritis is one of the rare complications of SLE, defined as vasculitis of the intestinal tract, with supportive biopsy findings and/or image. However, lupus enteritis is seldom confirmed on histology or image and the changes of intestinal mucosa are nonspecific. Crohn’s disease is a chronic inflammatory disorder of the gastrointestinal tract which affects any part of the gastrointestinal tract. The diagnosis of CD is confirmed by clinical evaluation and a combination of endoscopic, histology, radiology, and/or biochemical investigations.
