Abstract

Introduction: collagenous colitis, is a subtype of microscopic colitis, which presents as a picture of diarrhea without blood, of insidious onset with periods of remission, exacerbation and abdominal pain. It has a prevalence of 10 to 15 per 100b000 inhabitants.

Clinical case: It is a case of a 27-year-old patient with watery diarrhea of 1 year 6 months of evolution, associated with food consumption and accompanied by abdominal discomfort, this person presents an increase in evacuation frequency. Fecal calprotectin was performed with a result of 516 ug/g, so upper and lower gastrointestinal endoscopy was decided, with normal endoscopic findings and histopathology with a colon report compatible with collagenous colitis. Food and trigger medication restrictions apply; therapy with bismuth subsalicylate is started, obtaining improvement.

Conclusion: in the case of unknown chronic diarrhea, the study must be exhaustive for an accurate diagnosis like this case of collagenous colitis to define a specific treatment.
