According to a study, the cutaneous biopsy of urticaria lesions may be divided into the following categories, as the response to treatment could be different:

  • Class 1 - A mixture of perivascular dermal inflammatory infiltrates composed of lymphocytes, monocytes, and neutrophils, eosinophils, or both

  • Class 2 - Inflammatory infiltrate chiefly composed of neutrophils [37]

  • Class 3 - Inflammatory infiltrate mainly composed of eosinophils
