Spongiosis of epidermis Q is the histological hallmark of dermatitis (eczema). Contact dermatitis is diagnosed by patch testQ & Atopic dermatitis is diagnosed by clinical examinationQ. Clinical criteria for diagnosis of atopic dermatitis Family h/o allergy/atophy Personal history of allergy/atophy i.e. presence of other atopic condition asQ - rhinitis, hay fever, asthma, food allergy or eczemaQ.
