OBJECTIVE: To examine the potential role of angiogenesis in leprosy. DESIGN: Immunohistochemical analysis of leprosy lesions. SETTING: Department of Dermatology, Venereology, and Leprology, Kasturba Medical College; Division of Dermatology, University of California at Los Angeles; and Departments of Dermatology and Pathology, Emory University. PATIENTS: Thirty-two cutaneous lesions that represented the spectrum of leprosy were obtained from 32 patients. MAIN OUTCOME MEASURE: CD31 microvessel counts. RESULTS: The mean CD31 microvessel count in borderline tuberculoid, midborderline, and lepromatous leprosy lesions was significantly higher than in indeterminate leprosy lesions. CONCLUSIONS: Increased bacterial load is associated with increased angiogenesis. Angiogenesis inhibitors may be of benefit in the treatment of leprosy.
