Neonate with blotchy rash on the abdomen. Diagnosis is:

Ans. (c) Erythema toxicum neonatorum.* Erythema toxicum neonatorum presents in neonates with blotchy maculopapular rash with pustules. These pustules are sterile and contain eosinophils and the rash usually settles by day 10 of life.* Cutis marmorata presents with mottling which disappears when the skin becomes warmer. The mottling is likely to disappear beyond neonatal period. Persistence beyond neonatal period may be associated with hypothyroidism, trisomy 21 and Cornelia de Lange syndrome.
