Localized scleroderma may be triggered by chronic venous insufficiency (CVI). Treating CVI can improve localized scleroderma symptoms at affected vein sites.

Area of Science:

  • Dermatology
  • Vascular Biology

Background:

  • Localized scleroderma is a skin condition with unknown causes, involving inflammation and hardening.
  • Previous reports suggest a link between localized scleroderma and chronic venous insufficiency (CVI).

Observation:

  • Three new patients presented with localized scleroderma specifically at sites of insufficient veins.
  • Treatment targeting the underlying CVI resulted in significant improvement of the scleroderma lesions in these areas.

Findings:

  • Chronic venous insufficiency (CVI) may create a local microenvironment conducive to localized scleroderma.
  • CVI-induced local hypoxemia leads to cytokine release, endothelial activation, and leukocyte infiltration.
  • Leukocytes release factors like transforming growth factor beta, promoting collagen synthesis and skin sclerosis.

Implications:

  • Chronic venous insufficiency (CVI) is identified as a potential trigger for localized scleroderma.
  • Treating CVI may resolve localized scleroderma if it is a contributing factor.
  • This suggests a multifactorial etiology for localized scleroderma, treatable by addressing CVI.
