🔑 Key Principles — Nelson Chapter 688
• Erythema toxicum neonatorum: 50% of full-term infants, day 2 of life. Yellow-white papules/pustules with erythematous flare. Eosinophils on smear. Self-limited.
• Transient neonatal pustular melanosis (TNPM): Present at birth, pustules → hyperpigmented macules. No erythema. Neutrophils on smear.
• Miliaria: Crystallina (clear vesicles, no erythema), rubra (red papulovesicles, prickly heat). Heat/sweat retention.
• Nevus simplex (salmon patch): Glabella, eyelids, nuchal area. 40-60% of newborns. Fades on face, persists on nuchal area.
• Congenital dermal melanocytosis (slate gray nevus): Sacral/gluteal blue-gray macules. Fades in early childhood. Avoid term 'Mongolian spot'.
• Aplasia cutis congenita: Scalp vertex ulcer/scar. Hair collar sign. Rule out underlying neural tube defect if midline, multiple, or large.
