Nevus Sebaceous

Nevus sebaceous, often called “NS,” is a common skin condition that usually appears at birth or during childhood. While it is typically harmless, understanding its causes, symptoms, diagnosis, and available treatments can help those affected manage the condition effectively.

Types of Nevus Sebaceous

Nevus sebaceous can occur in different forms, including:

Causes of Nevus Sebaceous (NS)

Nevus sebaceous is primarily caused by a genetic mutation. Here are 20 simplified causes:

  1. Genetic Mutation: NS is usually present from birth because of a change in a person’s genes.
  2. Developmental Factors: It can occur during fetal development when skin cells don’t form correctly.
  3. Hormonal Changes: Hormonal fluctuations may trigger NS growth during puberty or pregnancy.

  11. Hormone Disorders: Hormonal imbalances could play a role in some cases.
  12. Sun Exposure: Prolonged sun exposure may aggravate NS.
  13. Immune System Factors: Immune system issues might influence NS development.
  14. Injury: Trauma to the affected area can trigger NS growth.
