Crohn's disease: beyond the intestine.

We present the case of a 41-year-old patient under study for chronic diarrhea, iron deficiency, and elevated fecal calprotectin. After ileocolonoscopy, magnetic resonance and capsule endoscopy without alterations, an upper endoscopy was performed visualizing fibrinated serpinginous ulcers, confluent with each other, with erythematous mucosa between them, suggestive of isolated gastric Crohn's disease, a rare entity in the adult population.
