Protein losing enteropathy in severe atopic dermatitis in an exclusively breast-fed infant.

We first report a case of protein losing enteropathy in severe atopic dermatitis in an exclusively breast-fed 5-month-old infant. Protein losing enteropathy was confirmed by fecal alpha1-antitrypsin clearance test and imaged successfully by 99mTc-human serum albumin scintigraphy. The present case highlights that protein losing enteropathy in severe infantile atopic dermatitis is being a topic of concern and also an issue even in exclusive breast feeding patients.
