Abstract:
Three patients with a rare extrafacial granuloma eosinophilicum are presented. Lesions were localized on the scalp, the upper back or the upper arm. Only one patient had a typical facial granuloma eosinophilicum at the same time. Diagnosis was established by histopathology. The histopathological findings vary with the age of the lesion. Early lesions are characterized by a vasculitis with many eosinophils separated by a Grenz zone from epidermis and follicular structures. With time the inflammation changes and hyalin fibrosis takes place.
