Summary

Takayasu arteritis (TA) can present with skin issues like necrotizing vasculitis. Recognizing these cutaneous manifestations is crucial for early diagnosis and treatment of this large artery inflammatory disease.

Area of Science:

  • Vascular Biology
  • Dermatology
  • Rheumatology

Background:

  • Takayasu arteritis (TA) is a large artery inflammatory disease affecting the aorta and its branches.
  • TA typically presents in two phases: an initial inflammatory stage and a later 'pulseless' stage with stenosis and aneurysms.
  • Skin manifestations, including nodules and ulcers, have been noted in TA patients.

Observation:

  • This study reports two patients with TA where cutaneous necrotizing vasculitis was the initial presentation.
  • A literature review identified eight similar cases, highlighting TA's involvement beyond large arteries.

Findings:

  • Takayasu arteritis involves not only large arteries but also small blood vessels.
  • The inflammatory process in TA's large arteries affects areas supplied by vasa vasorum, similar to cutaneous vessels.

  • This suggests small vessel involvement may contribute to TA's pathology.

    • Implications:

    • Cutaneous necrotizing vasculitis can be a presenting sign of Takayasu arteritis.
    • Awareness of TA's skin manifestations aids in prompt diagnosis and crucial treatment initiation.
    • Understanding small vessel involvement deepens insights into TA pathogenesis.
