Tissue eosinophilia as an indicator of drug-induced cutaneous small-vessel vasculitis Bahrami S; Malone JC; Webb KG; Callen JPArch Dermatol 2006[Feb]; 142 (2): 155-61OBJECTIVE: To determine whether tissue eosinophilia is a reliable indicator of a drug-induced etiology in biopsy samples demonstrating leukocytoclastic vasculitis. DESIGN: Retrospective medical record review with concurrent histopathologic analysis. SETTING: University-affiliated dermatology practice. PATIENTS: Sixty-three patients with cutaneous small-vessel vasculitis meeting specific inclusion criteria were divided into drug-induced (n = 16) and non-drug-induced (n = 47) groups. MAIN OUTCOME MEASURES: Corresponding histopathologic material was reviewed by a dermatopathologist masked to the etiologic associations. An eosinophil ratio was calculated for each patient, derived from the mean eosinophil score (averaging eosinophil counts from 10 high-power histologic fields), and expressed in relation to the intensity of inflammation in the histopathologic slides examined. Eosinophilia ratios were compared for both groups using the Mann-Whitney test. RESULTS: A significant difference was found in mean eosinophil ratios in the drug-induced vs non-drug-induced groups (5.20 vs 1.05; P = .01). Vascular fibrin deposition was present in both groups and was not found to be significantly different (P = .78). Clinical evidence of systemic vasculitis was present in 2 patients (13%) in the drug-induced group vs 15 (32%) in the non-drug-induced group. Fourteen patients (88%) in the drug-induced group had a short-term disease course vs 27 (57%) in the non-drug-induced group. CONCLUSIONS: Tissue eosinophilia is established as a reliable indicator of drug induction in cutaneous small vessel vasculitis. Drug-induced small-vessel vasculitis generally follows a short-term disease course without development of systemic involvement. This information may be useful for guiding management decisions, especially when the etiology is unclear.|Adolescent[MESH]|Adult[MESH]|Aged[MESH]|Aged, 80 and over[MESH]|Anti-Bacterial Agents/*adverse effects[MESH]|Biopsy[MESH]|Child[MESH]|Child, Preschool[MESH]|Diagnosis, Differential[MESH]|Eosinophilia/etiology/*pathology[MESH]|Female[MESH]|Follow-Up Studies[MESH]|Humans[MESH]|Male[MESH]|Middle Aged[MESH]|Retrospective Studies[MESH]|Severity of Illness Index[MESH]|Skin/*pathology[MESH]|Vasculitis, Leukocytoclastic, Cutaneous/*chemically induced/complications/pathology[MESH] |
