Differential diagnoses of diaper dermatitis.

Diaper dermatitis is the most common contact eczema present in early childhood. The main cause is an irritant reaction to urine and feces, which is facilitated by the occlusive conditions under the diaper, leading to hyperhydration of the stratum corneum (diaper dermatitis). In addition, diaper pressure and friction can increase the risk of skin inflammation, which also opens the skin up to other irritant agents, allergens, and infectious agents, such as candida albicans. However, a variety of diseases are associated with inflammation of the skin in the diaper region, therefore the term "diaper dermatitis" is merely descriptive and does not reflect anything about the etiopathogenesis. The term diaper dermatitis refers only to an inflammation in the diapering area and should not be automatically equated with reactions to diapers. Making the correct diagnosis requires a thorough examination of the skin in its entirety and a detailed report of the patient's medical and family history. Once a specific pattern is identified, a precise diagnosis, and an appropriate therapy, can be determined.
