examination with a Wood lamp. The lamp enhances the contrast between
the macule and normal skin. Normal infants may occasionally have a single
lesion, but the presence of one or more of these macules in an infant with
neurological problems strongly suggests the diagnosis of tuberous
sclerosis. A skin biopsy is not diagnostic.
Indurated violet or red plaques or sharply defined subcutaneous nodules on
the buttocks, thighs, trunk, face, or arms are most likely which of the
following?
Intracutaneous hemorrhage

Neonatal pustular melanosis
Staphylococcal impetigo - ✔✔Neonatal pustular melanosis
Transient neonatal pustular melanosis is similar to miliaria but is present at

commonly occurs on the face, the palms of the hands, and the soles of the
feet, and is most often seen in black infants. If the lesion contents are
smeared on a slide and stained, they are found to be amorphous debris.
These lesions are neither infectious nor contagious, and require no
treatment.
