Neutrophilic urticarial dermatosis (NUD) is an uncommon and not well understood disease. We report a 24-year-old female with persistent present with pruritic and painful urticarial plaques unresponsive to convential treatment. Histopathologically, it demonstrates a perivascular and interstitial neutrophilic infiltrate with leukocytoclasia without evidence of vasculitis or dermal edema consistent with neutrophilic urticarial dermatosis. Further investigations to rule out underlying autoimmune, autoinflammatory and gentic systemic disease were negative. Furthermore, the cutaneous eruption was resistant to multiple therapeutic interventions including colchicine and dapsone treatment, and show significant response to treatment with anakinra, interleukin-1 receptor antagonist. Based on literature review, the case reported here is the second case with clinical and pathologic features of NUD without systemic disease and the first case of NUD that showed resistant to colchicine and dapsone treatment, with adequate response to anakinra.

Backgrounds: A large proportion of patients with chronic spontaneous urticaria (CSU) are resistant to a standard dose of antihistamine. Acknowledged biomarkers for identifying these patients have not been determined. The neutrophil/lymphocyte ratio (NLR) has been considered as an important indicator of inflammation in chronic diseases.

Introduction: The latest international EAACI/GA²LEN/EuroGuiDerm/APAAACI guideline for urticaria recommends limited laboratory testing for chronic spontaneous urticaria (CSU) and selective testing for only certain chronic inducible urticaria (CIndU) subtypes, though the rationale for these recommendations is poorly explained. This study aimed to improve the understanding of CIndU subtypes by comprehensively comparing their demographic, clinical, and laboratory characteristics with those of the better-characterized CSU.
Methods: We conducted a retrospective analysis of 567 patients (median age 41 years, 67% female) diagnosed with CSU, symptomatic dermographism (SD), cold urticaria (ColdU), cholinergic urticaria (CholU), and delayed pressure urticaria (DPU).
