Eosinophilic gastroenteritis (EGE) is considered distinct from eosinophilic colitis (EC). A 59-year-old man presented with a colonic tumor, who had resolution of pain and diarrhea after surgery, then 7 months later developed proton-pump inhibitor-responsive dysphagia with esophagitis, and 9 months later presented again with pain and diarrhea where EGE with concurrent eosinophilic esophagitis was diagnosed. Review of the resected tumor specimen identified EC with an adenoma. Workup revealed tuberculosis and latent hepatitis B virus requiring treatment before commencing immunosuppressive therapy plus a 6-food elimination diet that led to complete resolution within 3 weeks. EC may precede EGE and eosinophilic esophagitis.
Keywords: eosinophilic colitis; eosinophilic esophagitis; eosinophilic gastroenteritis; eosinophilic gastrointestinal disease.
