Abstract
The case of a 21-day-old boy with eosinophilic enteritis with intestinal stricture due to a food protein-induced allergy is reported herein. For the first 4 days of life, he was both breast-fed and formula-fed, after which he was exclusively breast-fed. At the age of 24 days, he underwent laparotomy to investigate the possibility of intestinal obstruction for bilious vomiting, and an ileal stricture was detected and resected. Pathologic analysis showed the presence of eosinophil accumulation in the lesions presented more than 20 eosinophils per high-power field and the eosinophils were oriented towards the epithelium and diffusely distributed throughout the tissue, but the margins of resection showed a few infiltration of eosinophiles. Allergen-specific lymphocyte stimulation testing showed a markedly increased lymphocyte response to lactoferrin. He was finally diagnosed as eosinophilic enteritis with intestinal stricture due to a food protein-induced allergy. The patient remained asymptomatic during a follow-up period of 12 months.
