Irritant contact dermatitis

March 20, 2009

This picture is in step2 secrets, but also can be found online. There is something tricky related to the “diapers” with atopic dermatitis and irritant contact dermatitis in infants. There is an UW Qs about that too.

When the case present a child w/ Sx of atopic dermatitis, but spared diaper area, it is still atopic dermatitis. Because of the moisture in the diaper area, atopic dermatitis may not be present.

When the infant has rash in the diaper area, it is due to a type of irritant contact dermatitis very well known to many parents as diaper rash aka napkin rash.

Don’s also confuse irritant contact dermatitis w/ contact dermatitis. The former is due to irritating reaction to chemical or other substances (saliva,urine,stool), the latter is type IV hypersensitivity.

If any mistakes, please correct.
