Vesicles, bullae, and pustules in the newborn may be caused by infections, congenital disorders, or other diseases. Benign and self-limited disorders, including erythema toxicum neonatorum (picture 1A), transient neonatal pustular melanosis (picture 2A-B), and neonatal acne (picture 3), do not require specific therapy.
Is pustular melanosis contagious?
Contagious isolation is unnecessary for transient neonatal pustular melanosis.
How long does neonatal pustular melanosis last?
The prognosis for transient neonatal pustular melanosis is good. The vesicles and pustules usually resolve within 48 hours, while the brown macules usually fade over 3-4 weeks but may persist for several months.
Is Melanosis contagious?
These patches are dark brown and may be slightly or significantly darker than the surrounding skin on the penis. Penile melanosis does not cause any other symptoms. The condition is not infectious or contagious, and there is no way to pass it on to other people.
What is the difference between vesicles and pustules?
Pustule: a circumscribed, elevated lesion filled with purulent fluid, less than 1 cm in size (e.g. erythema toxicum neonatorum, acne). Vesicle: a circumscribed, elevated, fluid-filled lesion up to 1 cm in size (e.g. herpes simplex).
What is the difference between a pustule and a blister?
Vesicles are small blisters containing clear fluid. Bullae are large blisters containing clear fluid. Pustules are circumscribed lesions that contain dense cellular content.
When does pustular melanosis go away?
Blisters usually resolve within 48 hours. The remaining dark spots will gradually fade over weeks to months. Lesions may occur singly or in groups. Transient neonatal pustular melanosis may occur on any part of the newborn’s body.
How is pustular melanosis treated?

What does a vesicle look like?
Appearance. A typical vesicle looks like a little bubble of fluid under the skin. The larger the vesicle, the more prone to breaking open, which can be quite painful. It can also cause inflammation in the surrounding area.
Should you pop vesicles?
Popping a vesicle isn’t typically advised. This can leave the area open to infection and make it take longer to heal. Unless the vesicle becomes large and exceptionally painful, leaving it alone is best.
What is transient neonatal pustular melanosis?
Transient neonatal pustular melanosis is an uncommon benign pustular condition presenting in newborn infants. It is also known as transient neonatal pustular dermatosis and transient neonatal pustulosis.

What are the different types of neonatal pustular dermatoses?
