Typical Observation for a Rare Neonatal Pustular Dermatosis

Abstract

This case report discusses a rare presentation of transient neonatal pustular melanosis (TNPM) in a full-term newborn. The female infant, born via vaginal delivery at [38 weeks], presented shortly after birth with characteristic pustular lesions that rapidly evolved into hyperpigmented macules, a hallmark of TNPM. The pustules, which appeared on the neck, and other areas of the body, resolved spontaneously within 3 weeks, leaving behind the distinctive pigmentary changes without scarring. The mother had an uncomplicated pregnancy with a remarkable finding in the medical history, and the newborn showed no signs of systemic involvement. TNPM, while benign and self-limiting, can be clinically confused with other neonatal skin conditions, such as neonatal herpes or bacterial infections, which may lead to unnecessary interventions. This case highlights the importance of early recognition of TNPM and its typical clinical course, emphasizing the need for appropriate diagnosis and reassurance for both parents and healthcare providers. A review of the literature on TNPM, its pathogenesis, and management is also provided.
