Abstract | BACKGROUND: OBJECTIVE: To compare the histopathologic features of chronic urticaria patients testing positive for anti-IgE receptor antibody (Ab) to those testing negative. METHODS: Totally, 438 patients with a clinical presentation of chronic urticaria (2011-2013) had anti-IgE receptor Ab tested and 37 of those patients had skin biopsy. We evaluated microscopic features including: spongiosis, dermal edema, presence of mast cells, density of lymphocytic infiltration, predomination of eosinophils/neutrophils; intravascular neutrophils and presence of vasculitis. The aforementioned features were compared between negative and positive anti-IgE receptor Ab groups. RESULTS: Of 37 patients , 69% were women and 31% were men. 49% had positive anti-IgE receptor Ab and 51% had negative anti-IgE receptor Ab. In the positive anti-IgE receptor Ab group, 83% showed intravascular neutrophils. Eosinophil predominance was identified in 72% and neutrophil predominance was identified in 28%. In the negative anti-IgE receptor Ab group, 89% showed intravascular neutrophils. Eosinophil predominance was identified in 53% and neutrophil predominance was identified in 47%. There was no evidence of vasculitis in either group. CONCLUSION: There were no significant histopathologic differences between the anti-IgE receptor Ab positive and negative cases. Therefore, serum testing for anti-IgE receptor Ab is required to identify this subgroup of chronic urticaria patients.
