Primary cutaneous vasculitis typically presents as palpable purpura on extremities and has a benign outcome. Secondary vasculitis prognosis depends on the underlying condition, not histopathology.

Area of Science:

  • Dermatology
  • Pathology
  • Immunology

Background:

  • Cutaneous vasculitis encompasses a spectrum of inflammatory conditions affecting skin blood vessels.
  • Understanding its clinicopathologic features is crucial for accurate diagnosis and management.

Purpose of the Study:

  • To characterize the clinicopathologic features of cutaneous vasculitis.
  • To evaluate the therapeutic outcomes in patients with cutaneous vasculitis.

Main Methods:

  • Retrospective analysis of 50 biopsy-proven cutaneous vasculitis cases from January 1998 to July 1999.
  • Histopathological examination and clinical correlation, including direct immunofluorescence (DIF).

Main Results:

  • Palpable purpura on extremities was the most common presentation across all ages and sexes.

  • Histopathology showed diverse patterns, from acute to chronic, including bullous and granulomatous changes.
  • Direct immunofluorescence supported immune-mediated pathogenesis in 13 of 21 cases.

    • Conclusions:

    • Primary cutaneous vasculitis generally has a favorable clinical course and outcome.
    • The prognosis of secondary cutaneous vasculitis is dictated by the associated systemic disease, irrespective of skin biopsy findings.
