NEVUS SEBACEOUS:

Small NS may be observed, especially in infants and younger children.

Surgical removal may be recommended for larger lesions, those that may lead to significant cosmetic disfigurement or if it interferes with personal grooming (eg. combing of hair), and if there is suspicion of cancerous change.

EPIDERMAL NEVUS:

EN may be left alone. If treatment is required, treatment options include cryotherapy with liquid nitrogen, dermabrasion, electrosurgery, lasers and surgical removal.

CONGENITAL MELANOCYTIC NEVUS:

Treatment of CMN depends on the size, site and potential cosmetic effects.

Small and medium sized CMN may be observed. Parents and patients are taught to monitor for changes within the CMN. If there are any concerns, these can be removed by surgery.

Suspicious features that need to be observed for are:
  • A: Asymmetry
  • B: Borders (irregular, blurred)
  • C: Colour (blue, black, red and white)
  • D: Diameter (rapid increase in size)
  • E: Evolution (change over time)

Treatment of large CMN are more complex and require in-depth discussion with your dermatologist, plastic surgeon and paediatrician.

Sun protection is important. Measures include:
  • Avoidance of direct sun between 10.00am to 4.00pm.
  • Use of sunscreens with at least SPF 30 and protection against UVA and UVB.
  • Use of hats, shades and umbrellas when under direct sun.
