title: [Perforating annular granuloma].
abstract: This study presents the first Venezuelan case of perforating granuloma annulare in an eleven year-old patient. The cutaneous eruption was characterized by minute lichenoid papules which have persisted for two years. These lesions were asymptomatic and most perforating, appearing in the dorsal side of hands and fingers. The histopathological study showed a classical granuloma annulare with sites of necrobiosis and perforation of the epithelium. This "transepithelial perforation" allows the elimination of collagen and cell detritus observed. The patient responds well to the injection of steroids into lesions.
