Management of Congenital Melanocytic Nevi with Progressive Facial Asymmetry

Diagnostic Considerations

The American Academy of Pediatrics recommends referral to a pediatric dermatologist or general dermatologist with expertise in congenital lesions within days to weeks for proper evaluation of the eyelid nevus 2
The American Academy of Pediatrics suggests examining for concerning features that warrant urgent evaluation, including rapid growth, color variation, development of nodules or papules, bleeding, ulceration, or persistent erosions, and pain or significant pruritus 2, 3, 4
The American Academy of Pediatrics recommends obtaining MRI of brain and spine to screen for neurocutaneous melanosis if the nevus is medium-to-large or if multiple congenital melanocytic nevi are present 3

The American Academy of Pediatrics recommends monitoring protocol every 3 months during the first year, given growth and location concerns, and annual dermatology evaluation minimum after the first year if stable 2, 3, 4
The American Academy of Pediatrics suggests skin care including gentle cleansing with water alone or nonsoap cleanser, applying bland emollient, and using low-to-mid-potency topical corticosteroids for pruritus 2, 4
The American Academy of Pediatrics recommends complete excisional biopsy preferred over shave biopsy if suspicious changes present 2

The American Academy of Pediatrics advises against performing ablative procedures as these obscure future melanoma evaluation and cause frequent pigment recurrence 3, 4
The American Academy of Pediatrics warns against assuming irritation or growth is benign, as melanoma in congenital nevi can present as deep nodules without overlying color change 4
The American Academy of Pediatrics emphasizes the importance of not delaying referral, as progressive facial asymmetry in a young child may indicate underlying craniofacial disorder requiring early intervention 1

The overall melanoma risk in congenital melanocytic nevi is 0.7-1.7%, increasing with projected adult size >40 cm, multiple satellite nevi, trunk location, and presence of neurocutaneous melanosis 3
