    Summary
    This summary is machine-generated.

    This study investigated delayed pressure urticaria in a 40-year-old man. Complement levels remained normal, suggesting no significant immunologic reaction in this case of delayed pressure urticaria.

    Area of Science:

    • Immunology
    • Dermatology
    • Allergy

    Background:

    • Delayed pressure urticaria is a rare condition characterized by hives appearing hours after pressure is applied.
    • The underlying immunologic mechanisms of delayed pressure urticaria are not fully understood.

    Observation:

    • A 40-year-old male patient with delayed pressure urticaria was studied.
    • Serum was analyzed for quantitative complement components during active whealing.

    Findings:

    • No consumption of complement components was observed.
    • Total hemolytic complement levels remained unchanged, even during active phases of urticaria.

    Implications:

    • The findings provide limited evidence for a significant immunologic reaction involving complement in this patient's delayed pressure urticaria.
