RESUMO

Abstract Multinucleate cell angiohistiocytoma is a rare, benign vascular proliferation of unknown etiology. It occurs mainly in middle-aged women and usually affects the acral regions; the lesions appear as discrete, grouped, and asymptomatic violaceous papules. Histopathology shows proliferation and dilated small vessels in the papillary dermis, fibrous stroma with thickened collagen bundles, and multinucleated giant cells. To date, there are approximately 140 cases described in the indexed literature. This report presents the case of a 62-year-old woman with a typical clinical condition, who chose not undergo treatment, considering the benign character of her illness. The clinical and immunohistological aspects of this unusual dermatological entity are emphasized.
