Newborn Skin: Part I. Common Rashes and Skin Changes

Area of Science:

• Neonatal Dermatology
• Pediatric Infectious Diseases

Background:

• Newborn rashes are frequent, with most being benign.
• Infections present with pustules or vesicles, especially in unwell infants or those with congenital infection risk factors.

Purpose of the Study:

• To review common and concerning rashes in newborns.
• To highlight key differentiating features for diagnosis and management.

Main Methods:

• Literature review of common neonatal skin conditions.
• Discussion of infectious etiologies and their dermatological signs.
• Comparison of benign and pathological rashes.

Main Results:

• Congenital cytomegalovirus can cause hearing loss and developmental delay, with skin signs like petechiae.
• Congenital syphilis presents with characteristic copper-red lesions on hands and feet.
• Benign rashes include erythema toxicum neonatorum, neonatal pustular melanosis, neonatal acne, milia, cutis marmorata, and harlequin color change.

Conclusions:

• Prompt identification of infectious rashes is vital to prevent long-term sequelae.
• Understanding the spectrum of neonatal rashes aids in appropriate clinical management.
• Differentiating benign from serious conditions ensures timely intervention for at-risk infants.
