Mimics of Dermatitis.

Dermatitis is a common condition frequently encountered by dermatologists. The diagnosis of dermatitis can be challenging because this condition is often multifactorial, and many skin diseases that can mimic dermatitis should be considered in the differential diagnosis. It is important to recognize and be familiar with these conditions because some of them can represent signs of systemic disease or malignancies and misdiagnosis can lead to mismanagement and adverse outcomes for the patient.
