Salmon Patch

Salmon patch, also known as nevus simplex or angel’s kiss, is a common type of birthmark that appears as a flat or slightly raised pink or red patch on the skin. This harmless birthmark appears as a flat, pink or red patch on the skin, resembling a salmon’s coloration. Although salmon patches typically fade on their own within a few years. This harmless condition is usually present at birth or develops shortly afterward. Salmon patches are caused by the dilation of tiny blood vessels near the surface of the skin. This dilation is believed to be due to immature blood vessel development in infants. While the exact cause is not known, it is thought to be a result of genetic factors and normal variations in blood vessel development during fetal growth.

Types

Types of Salmon Patch:

  1. Forehead Salmon Patch: The forehead salmon patch is the most common type and appears as a flat, pinkish-red mark on the baby’s forehead, between the eyebrows, or above the nose. It is often called an “angel’s kiss” when it occurs between the eyebrows.
  2. Eyelid Salmon Patch: This type of salmon patch is located on the eyelids, resulting in pinkish or reddish patches. It is also known as an “angel’s kiss” when found on the upper eyelids.
  3. Neck Salmon Patch: Neck salmon patches appear on the back of the baby’s neck and are frequently referred to as “stork bites.” These patches are usually harmless and tend to fade over time.
  4. Upper Lip Salmon Patch: An upper lip salmon patch, also called a “angel’s kiss,” occurs on the upper lip. It may appear as a single spot or as multiple smaller marks.

Causes

Possible causes of salmon patches, using simple language to ensure easy understanding. Dive in to explore the reasons behind these intriguing birthmarks.

  1. Genetic Factors: Genetic factors play a significant role in the development of salmon patches. These birthmarks can be inherited from parents or may occur spontaneously due to genetic mutations. Certain genes related to blood vessel development and pigmentation regulation are thought to influence the appearance of salmon patches.
  2. Blood Vessel Abnormalities: Abnormalities in the blood vessels near the skin’s surface can cause salmon patches. These birthmarks occur when the blood vessels dilate, leading to visible patches of pink or red discoloration. Changes in blood flow or vessel structure can contribute to these abnormalities.
  3. Hormonal Changes: Hormonal changes during pregnancy can result in the formation of salmon patches in newborns. Fluctuations in hormone levels, such as estrogen, can affect blood vessels and pigmentation, leading to the appearance of these birthmarks.
  4. Pressure on the Skin: Sustained pressure on the skin during birth or in the womb can cause salmon patches. Pressure from the birthing process or contact with the mother’s pelvis can create temporary disruptions in blood flow, resulting in the formation of these marks.
  5. Maternal Smoking: Maternal smoking during pregnancy has been linked to an increased risk of salmon patches in newborns. The chemicals present in cigarettes can affect fetal development, including blood vessels and pigmentation, potentially leading to the appearance of these birthmarks.
