A rare case of localized scleroderma led to a stroke in a Japanese woman. The condition caused artery narrowing, resulting in ischemic stroke and hemiparesis.

Area of Science:

  • Neurology
  • Dermatology
  • Vascular Medicine

Background:

  • Localized scleroderma is a rare autoimmune condition affecting the skin and connective tissues.
  • Cerebrovascular events are not commonly associated with localized scleroderma.
  • This case highlights a potential link between skin-related autoimmune disease and cerebrovascular complications.

Observation:

  • A 73-year-old Japanese woman presented with localized scleroderma on her scalp and progressive left hemiparesis.
  • Brain MRI revealed an ischemic stroke in the right middle cerebral artery territory, extending into deep white matter with hemorrhages.
  • Magnetic resonance angiography showed focal stenosis in the M2 segment of the right middle cerebral artery.

Findings:

  • Scalp biopsy demonstrated thickened vessel walls and mononuclear cell infiltration, suggesting an inflammatory process.

  • The patient's neurological deficits were attributed to hemodynamic compromise caused by the sclerotic arterial stenosis.
  • An autoimmune pathogenesis is proposed for the observed cerebrovascular event.

    • Implications:

    • This case suggests that localized scleroderma may be an underrecognized cause of ischemic stroke in specific vascular territories.
    • Understanding the link between autoimmune skin conditions and cerebrovascular disease is crucial for early diagnosis and management.
    • Further research is warranted to elucidate the mechanisms connecting scleroderma and stroke, potentially involving autoimmune-mediated vasculopathy.
