Xanthogranuloma: Report on Clinical and Histologic Findings in 64 Patients

Although xanthogranulomas are frequently encountered by pediatricians and dermatologists, data on the course of this tumor are restricted to several series with limited follow-up. We report on our experience with 64 patients whom we were able to identify from the surgical files. Our data support the currently held view that xanthogranulomas are generally benign, self-limited lesions. They may persist or continue to erupt for years, however, particularly in individuals who develop the first lesion after age 20 years.
