pustular melanosis
Benign neonatal skin condition presenting with small pustules that rupture leaving hyperpigmented macules.
Full Definition
Transient neonatal pustular melanosis is a benign skin condition affecting newborns, characterized by small, superficial pustules that rupture within the first few days of life, leaving behind small hyperpigmented macules with a collarette of scale. The condition is more common in African American infants and can be present at birth or develop within the first few days. The pustules contain neutrophils but are sterile, and the condition resolves spontaneously without treatment. Recognition is important to avoid unnecessary antibiotic treatment or invasive evaluation for infection.
Usage
Usage note: Often preceded by 'transient neonatal' for clarity. Emphasize benign nature in documentation.
