What does it mean when a newborn has purple feet?
One of the most common conditions in newborns with purple feet is circulation problems [1].
Purple feet can also be a sign of blue baby syndrome. However, in this syndrome, the whole body is typically affected by the color change, and the skin of the newborn turns blue or purple [2].
The purple color of the feet can also be a consequence of hyperpigmentation of the toes. It usually happens in babies with a darker shade of skin. It is not a pathological condition. The hyperpigmentation disappears on its own around the second year of life [3].
Rarely, purple feet in newborns can be caused by purple toe syndrome. The change of color, especially of the toes, occurs due to small blood clots in the foot vessels [4, 5].
Also, purple feet can result from neonatal purpura fulminans. This rare and severe condition has symptoms such as intravascular blot clothing, blockage of the vessels, and necrosis [6].
Nevertheless, purple feet in newborns can also be physiological. After birth, the baby may have a purple discoloration that fades away after several days [7].

For example, neonatal purpura fulminans, a dangerous condition, can present with purple feet [6]. However, it typically occurs in more than one region of the body [8].
A newborn with purpura fulminans can have severe anemia, and necrotizing tissues, which can be life-threatening [6].
If the child presents with purple changes on the feet and other parts of the body after birth, it can indicate an inborn cardiac defect [9]. Some congenital cardiac defects require treatment for the newborn to survive [10].
Purple feet in newborns with low birth weight can also be a sign of cutaneous aspergillosis. This fungal infection can lead to dangerous complications for the baby, like necrosis and regional circulatory failure [9].
These are just a few examples. However, what they show purple feet in newborns can indicate a dangerous condition.
