title: Clinicopathological correlation in chronic urticaria.
abstract: Except for urticarial vasculitis, histopathological studies on the different types of urticaria are scant in the medical literature. With the purpose of evaluating the histopathological changes that occur in chronic urticarial eruptions, and to correlate the histopathological findings with the clinical presentation of the patients, skin biopsy studies were done in 36 patients with chronic urticaria. Three well-defined histopathological patterns were found: namely neutrophilic, lymphocytic, and mixed type. No cases of vasculitis were found. No specific association to the clinical presentation of the patient was found.
