    Area of Science:

    • Nephrology
    • Rheumatology
    • Pathology

    Background:

    • Polyarteritis nodosa (PAN) is a systemic vasculitis.
    • Granulomatous inflammation can occur in some vasculitides.
    • Renal involvement is common in PAN.

    Observation:

    • A 61-year-old female presented with non-necrotizing granulomatous angiitis.
    • The primary pathology involved periarterial inflammation with giant cells.
    • No significant glomerular disease was observed.

    Findings:

    • Immunofluorescence studies were negative for immunoglobulin, complement, or fibrin deposition.
    • The observed vasculitis lacked necrotizing features.
    • Histopathology revealed a mixed mononuclear cell infiltrate with giant cells.

    Implications:

    • This case suggests an unusual variant of polyarteritis nodosa.
    • Steroid therapy demonstrated efficacy in managing this condition.
    • Further research may clarify the specific mechanisms and classification of such variants.
