Nevus simplex is caused by dilated capillaries near the skin’s surface, leading to increased blood flow in those areas during fetal development. The exact mechanism behind this vascular malformation is not entirely understood, but it is considered a normal variation in newborn skin development.
The formation of these patches occurs due to the dilation of blood vessels under the skin. This increased blood flow to the area results in the characteristic reddish appearance of nevus simplex. This condition is a normal and common occurrence in newborns and does not indicate any underlying pathology.
