Contact dermatitis, seborrheic dermatitis, and atopic dermatitis are all common causes of neonatal rash.

Erythema toxicum neonatorum is the most common type of neonatal rash, affecting up to 70% of newborns.

Diapers, wipes, and laundry detergents are all common causes of contact dermatitis in neonates.

Contact dermatitis can cause red, itchy patches of skin, blisters or pustules, and scaling or crusting.

Contact dermatitis is treated by avoiding the allergen, using topical corticosteroids, and taking antihistamines.

Seborrheic dermatitis in neonates is caused by a combination of overproduction of sebum and a Malassezia yeast infection.

Seborrheic dermatitis can cause yellow or white scales on the scalp, as well as red, scaly patches of skin on the face, chest, and back.

Seborrheic dermatitis is treated with topical antifungals and topical corticosteroids.

Atopic dermatitis in neonates is caused by a combination of family history of atopy and exposure to allergens.

Atopic dermatitis can cause dry, itchy skin, red, scaly patches of skin, and blisters or pustules.
