What is Erythema Toxicum Neonatorum?

Erythema Toxicum Neonatorum is a kind of skin rash which is most common in full-term newborns. It is a benign skin rash, self-limited, and does not lead to any other consequences. It can occur on any body part, like the abdomen, chest, face, neck, arms, and legs. This skin condition looks like a red rash with small white or yellowish bumps like papules (small bumps on the skin with distinct or indistinct borders) or fluid-filled blisters like sacs called vesicles. These rashes have the nature of disappearing from one place after a few hours to reappear in another spot.

These kinds of skin rashes are not usually found on the palm, feet, and sole of a newborn but can occur on other parts of the body. Erythema Toxicum Neonatorum is a temporary skin rash that occurs during the first week of birth and regresses within 7-15 days. This kind of skin disorder is rare in preterm babies. Erythema Toxicum Neonatorum occurs only on fully developed and matured skin of full-term babies. Though these vesicles look infectious, the condition is non-infectious and does not spread from one part to another part of the body.

What Causes Erythema Toxicum Neonatorum in Newborns?

There are different theories regarding the cause of Erythema Toxicum Neonatorum in newborns. One of them states that it can be due to the reaction of the meconium (stool passed by the newborn) to the skin. It is also known to happen due to the pilosebaceous unit, which is related to sebaceous glands that produce hair follicles.

This condition may be present in the places from where the hair follicles arise. It may also occurr due to the increased inflammation of the cells around hair follicles. Newborns will have a lot of hair on their bodies during their neonatal period (28 days of birth), except for feet, soles, and palms. It supports the theory, which states that Erythema Toxicum Neonatorum occurs due to the infiltrated eosinophils on the epidermis. Despite these theories, the root cause of Erythema Toxicum Neonatorum remains unknown.
