Key Points

Question  Could the dermatological identification of skin plaque plexiform schwannomas in children facilitate the early diagnosis and treatment of individuals with neurofibromatosis type 2 (NF2)?

Findings  This genetic testing study reports a case of an early diagnosis of NF2 in a child after genetic analysis of congenital skin plaques using skin plaque Schwann cells, which carry a double inactivation of the NF2 gene and are useful for genetic testing. We confirmed these findings by analyzing 6 additional skin plaques from 6 unrelated patients with NF2.

Meaning  Dermatological identification of skin plaque schwannomas in children would facilitate the early diagnosis and treatment of patients with NF2 before development of severe adverse effects.
