The differential diagnosis of atopic dermatitis in childhood.
Atopic is the most common of the dermatitides seen in infancy and childhood, but there are numerous other diseases that can mimic the skin findings. These include seborrheic dermatitis, immunodeficiency, and psoriasis in infancy; scabies, tinea corporis infection, perioral, nummular, contact, and molluscum dermatitis in childhood. It is sometimes extremely difficult to differentiate between ichthyosis and AD, and it is also important to differentiate AD from erythrodermic conditions including acrodermatitis enteropathica, biotin deficiency, and Netherton syndrome. A rare condition in children that may mimic AD is mycosis fungoides.
