A newborn diagnosed with congenital melanocytic nevus and malignant melanoma at birth underwent successful surgical excision and skin grafting. This rare case highlights early melanoma detection in infants with giant congenital nevi.

Area of Science:

  • Dermatology
  • Pediatric Oncology
  • Surgical Pathology

Background:

  • Congenital melanocytic nevi (CMNs) are benign pigmented skin lesions present at birth.
  • Giant CMNs can rarely harbor malignant melanoma.
  • Early detection and management of melanoma in newborns are critical.

Observation:

  • A 3-day-old infant presented with an exophytic pigmented growth on the back and chest.
  • The lesion was pathologically confirmed as a thoracolumbar congenital melanocytic nevus with focal malignant melanoma.
  • The infant underwent complete surgical excision and skin grafting at 3 days of age.

Findings:

  • Surgical excision with partial-thickness skin grafts was performed successfully.
  • Post-operative follow-up at 3 years shows no evidence of recurrence or distant metastases.

  • The case represents malignant melanoma diagnosed at birth within a giant congenital melanocytic nevus.

    • Implications:

    • This case underscores the importance of vigilant monitoring and prompt surgical intervention for congenital melanocytic nevi, especially large ones.
    • Early diagnosis of melanoma in infants, even at birth, is feasible and crucial for favorable outcomes.
    • Further research into the oncogenesis of congenital melanocytic nevi and associated melanoma is warranted.
