Histopathological Subtypes of Urticaria: Distribution and Clinical Significance #2267177 (License: Personal Use)

The chart breaks down urticaria cases by histopathological features: conventional urticaria (42.9%)-defined by non-neutrophilic infiltrates-is the predominant subtype, followed by predominance of intravascular neutrophils (19%) and interstitial dermal neutrophilia (17.9%). Neutrophilic venulitis accounts for 11.9%, while mixed patterns represent 8.3%. These distinctions are critical for diagnosing neutrophilic urticarial variants and guiding targeted therapy.

Used in dermatology or immunology educational resources, clinical review articles, or diagnostic guidelines to help clinicians interpret skin biopsy findings in chronic or recurrent urticaria. Matches user intent seeking evidence-based classification of urticaria subtypes for differential diagnosis.
