Small-vessel vasculitis involves inflammation of small blood vessels, presenting diverse symptoms. Diagnosis requires a comprehensive approach including history, physical exam, and various lab tests.

Area of Science:

  • Rheumatology
  • Immunology
  • Pathology

Background:

  • Small-vessel vasculitis encompasses diverse conditions characterized by inflammation of venules, capillaries, and arterioles.
  • Clinical presentations are pleomorphic, with leukocytoclastic vasculitis and palpable purpura being a common phenotype.

Purpose of the Study:

  • To provide a comprehensive overview of small-vessel vasculitis.
  • To highlight diagnostic approaches and associated etiologies.

Main Methods:

  • Review of clinical and histopathological features.
  • Discussion of diagnostic workup including serological and laboratory tests.
  • Consideration of potential etiologies and associated conditions.

Main Results:

  • Histopathology in leukocytoclastic vasculitis shows angiocentric inflammation, fibrinoid necrosis, and neutrophilic infiltration.
  • Etiologies are often idiopathic but can be linked to drugs, infections, malignancy, or connective tissue diseases.

Conclusions:

  • Small-vessel vasculitis diagnosis necessitates a thorough patient evaluation.
  • Diagnostic strategies integrate clinical findings, imaging, and extensive laboratory investigations, including antibody testing.
