In children, they may be due to genetic factors, viral or bacterial infections, or have an autoimmune etiology [1].

Detailed explanation-2: -The most common diseases in this category are psoriasis, seborrheic dermatitis, lichen planus, pityriasis rosea, and secondary syphilis. Exfoliative erythroderma is included here since it rarely may be a complication of a pre-existing papulosquamous disease such as psoriasis, seborrheic dermatitis, and lichen planus.
