Abstract

Immune dysregulation, polyendocrinopathy and enteropathy, X-linked (IPEX) syndrome is a rare disorder caused by loss-of-function mutations in the gene forkhead box protein 3 (FOXP3). IPEX patients frequently show chronic diarrhea (enteropathy) associated with villous atrophies in the small intestine. Our case is different from this classical information in the literature, since he presented with neonatal onset inflammatory bowel disease within the first months of life accompanied by deep ulcers throughout colonic mucosa. Moreover, he developed chronic lung disease during follow-up and histopathological examinations showed granulomas in both gastrointestinal tract and lung parenchyma. Genetic analysis revealed the diagnosis of IPEX syndrome with a germline mutation in FOXP3. Thus, our study provides an unusual presentation of IPEX syndrome with colitis and granulomas presence in histopathological examinations.
