Microscopic colitis is an uncommon intestinal disorder that presents with chronic diarrhea. It is treatable, but its diagnosis may often prove difficult specifically in developing countries as it requires a GI endoscopy unit and since its incidence is on rise now it needs a high index of suspicion followed by colonic biopsy for diagnosis. It is a condition diagnosed when a patient with chronic watery nonbloody diarrhea has an endoscopically or radiographically normal colon, but colonic mucosal biopsies show unique inflammatory changes; because the mucosa is not otherwise disrupted or ulcerated, diarrhea does not contain blood or pus. We present the case of a 53-year-old woman with pathogen-negative chronic diarrhea who is a k/c/o rheumatoid arthritis (RA) since past 12 years and hypothyroidism since past 5 years. She responded well to treatment of low-dose steroids after colonoscopy and colonic biopsy successfully hinted her illness. Conclusion: Patients with pathogen-negative chronic diarrhea having h/o multiple drugs intake or autoimmune diseases not responding to usual treatment should be subjected to a colonoscopy followed by biopsy to diagnose microscopic colitis.
