An Unusual Presentation of Erythema Toxicum Scrotal Pustules Present at Birth

Rashes in the first 4 weeks of life are common and can be alarming for both parents and medical staff. Many of these are entirely innocent and resolve spontaneously and reassurance of the parents is all that is required. It is important to be aware of such ‘benign’ rashes (as well as the appearance of preterm and post‐term skin) when assessing genuine pathology in the neonate. Pathological dermatoses may arise by a number of different mechanisms. Iatrogenic causes (medical procedures) can cause rashes/lesions both in utero and in the neonatal period. Transplacental transfer of antibodies, infection or malignant cells from mother to child is another mechanism for causing neonatal rashes. Infection can also be passed on from attendant medical staff. Finally, primary dermatoses may present early in the neonatal period, especially genodermatoses such as collodion baby and epidermolysis bullosa.

This chapter provides an overview of neonatal skin function and intrauterine skin development. The impact on the skin of gestational age at birth is discussed along with cutaneous complications arising from prematurity and neonatal medical procedures. Skin care practices and considerations for neonates are summarised and physiological appearances and changes are described. On overview of disordered skin in neonates is provided, including pustular eruptions, atrophic skin lesions, disorders of neonatal fat, colloidion baby, blueberry muffin baby, purpura fulminans and common neonatal dermatosis. The clinical manifestions in a neonate of transplacental transfer of maternal autoantibodies is evaluated, including in conditions such as pemphigus vulgaris, pemphigus foliaceus, herpes gestationis, lupus erythematosus and maternal malignancy. Finally, on overview of infective skin pathologies and clinical manifestations in neonates is provided including viral, bacterial and fungal pathogens.
