Retrospective analysis of adult patients with cutaneous leukocytoclastic vasculitis.
A retrospective analysis was conducted on 93 adult patients with cutaneous leukocytoclastic vasculitis from St. Vincent's Hospital Melbourne to determine the classification, aetiology, severity and prognosis of this population of patients. We developed a new classification system for the purposes of our study based on modifications to the Chapel Hill Consensus Conference definitions for vasculitic syndromes. The results of our study indicate that an obvious cause was not found in 44.1% of patients. Of the patients with secondary vasculitis, the commonest causes were drugs and infections, accounting for a total of 40.9% of patients. Extracutaneous involvement was found in 39.8% of patients. Patients with symptoms resolving in less than 3 months accounted for 59.1% of the population, whereas 24.8% of patients had either symptoms lasting three or more months or evidence of recurrent symptomatology. There were 6 deaths (6.91%) and the rest were lost to follow up. The majority of patients in this retrospective series were classified as having hypersensitivity vasculitis, which is a relatively benign disorder limited mostly to skin with a low incidence of extracutaneous involvement (15.8%). Nevertheless, evidence of systemic involvement or sepsis need to be excluded as this may have important implications for patient treatment and outcome.
