Benign neonatal skin findings

What it is

The material sets six newborn skin findings side by side as images with their names under them: Mongolian Spots, Nevus Simplex (Salmon Patch), Milia, Erythema toxicum, Strawberry Hemangioma and Neonatal Acne. Nothing is written beside the names, so what that page asks for is the name that goes with the image.

Two of the six turn up again elsewhere in the material, and they are the two that come with more than a name: erythema toxicum, which is called a benign newborn rash outright, and neonatal acne.

Causes and risk

As many as 20% of newborns will be affected by neonatal acne.

How it presents

Erythema toxicum is worked through a case. A 9-day-old boy is brought in for fever and fussiness, and his skin shows tiny, 1-3 mm, pustules with a surrounding rim of erythema on the trunk; no vesicular lesions are noted. The answer names those lesions on the trunk a benign newborn rash called erythema toxicum neonatorum.

Neonatal acne comes usually in the form of pustules confined to the cheeks, chin, eyelids and forehead.

For the other four the material gives the name under the image and no more: Mongolian Spots, Nevus Simplex (Salmon Patch), Milia and Strawberry Hemangioma.
