Idiopathic eosinophilic colitis as a presenting feature of chronic large bowel diarrhea

Abstract Eosinophilic gastrointestinal disorder (EGID) is a spectrum of gastrointestinal disorders with eosinophilic infiltration of gut without any known cause for such tissue eosinophilia. Eosinophilic gastrointestinal disorders can be sub grouped as eosinophilic esophagitis, eosinophilic gastroenteritis, and eosinophilic colitis. The least frequent manifestation of EGIDs is eosinophilic colitis. We present a case of 51-year-old male patient who presented with chronic painless large bowel diarrhea with a rare diagnosis of eosinophilic colitis.
