Transient neonatal pustular melanosis (TNPM) is a harmless skin lesion that heals into a brown blemish. The condition is most common in African-American infants. It is the likely cause of brown freckles called lentigines neonatorum found in 15 percent of African-American newborns. The condition is not dangerous; it will lead to unusual pigmentation that persists for about 3 months. The lesions of transient neonatal pustular melanosis are almost always present at birth. They are 1 to 3 millimeters long and usually appear on the chin, neck, forehead, back, and buttocks, as well as the palms of the hands and soles of the feet. The cause of the condition is unknown and it does not require treatment.
