Ans. B. Erythema Toxicum
Erythema toxicum neonatorum presents as
erythematous irregular blotchy flea-bitten rashes in the first 2 weeks of life. It is very common and is almost seen in 30-70% of normal neonates. It is thought to be an immune-mediated dysregulated inflammation with eosinophilic infiltration in the epidermal layers of the skin. Does not require any treatment as they spontaneously resolve within 2 weeks.
Milia are physiological keratin-filled cysts due to blocked eccrine glands appearing as whitish/yellowish pustules. These are also referred to as Epstein pearls
Erythema marginatum is seen in acute rheumatic fever
Erythema nodosum presents as acute reddish tender nodules on the shins, usually in older children and adults.
