Proteus syndrome, a rare hamartomatous disorder, presents with diverse abnormalities. This case highlights a Japanese boy with extensive skin lesions, hemihypertrophy, and neurological issues, marking the second reported instance in Japan.

Area of Science:

  • Medical Genetics
  • Dermatology
  • Pediatrics

Background:

  • Proteus syndrome is an extremely rare congenital hamartomatous disorder characterized by mosaic overgrowth and a wide spectrum of potential abnormalities.
  • The syndrome's variable presentation and rarity pose diagnostic challenges, necessitating detailed case reporting for better understanding.

Observation:

  • A 6-year-old Japanese boy presented with a complex array of symptoms that emerged by one year of age.
  • Manifestations included cerebriform skin tumors, soft masses, verrucous lesions, whorled patches, hemihypertrophy of the right lower extremity, lordoscoliosis, skull protuberance, and seizures.

Findings:

  • The patient exhibited significant developmental and neurological impairments, including hydrocephalus and mental retardation.
  • This case represents the second documented instance of Proteus syndrome in the Japanese population.

Implications:

  • This report contributes to the limited global data on Proteus syndrome, particularly within the Japanese demographic.
  • Further research into the genetic underpinnings and clinical spectrum of Proteus syndrome is crucial for improved diagnosis and management.
