Erythema toxicum neonatorum

Erythema toxicum neonatorum (ETN) is a common skin condition that affects newborn babies. It is also known as toxic erythema of the newborn and urticaria neonatorum.

Symptoms

ETN typically appears within the first few days after birth. It is characterized by small, firm, yellow-white papules or pustules on a base of red skin. These skin changes can appear anywhere on the body, but they are most common on the face, trunk, and extremities. The lesions may come and go over a period of several days.

Causes

The exact cause of ETN is unknown. However, it is not caused by an infection, allergy, or toxin. Some researchers believe that it may be a normal response to the baby's exposure to a new environment outside the womb.

Diagnosis

ETN is usually diagnosed based on its characteristic appearance. No specific tests are needed. However, if the diagnosis is uncertain, a doctor may take a sample of the fluid from a pustule to rule out an infection.

Treatment

ETN is a harmless condition that usually resolves on its own within a week or two. No specific treatment is needed. However, it is important to keep the baby's skin clean and dry to prevent secondary infections.
