An unknown dermatosis was observed in an infant girl. During the newborn period, she had a generalized, patchy, erythematous eruption of about 60 round erythematous patches on the trunk, thighs, head, labial mucosa, and palate. After a few weeks, the lesions became whitish, atrophic, and depressed, and they were surrounded by an erythematous and slightly infiltrated border, which was occasionally lobulated. Histologically, the lesions demonstrated a thin epidermis overlying an edematous dermis. Around the border of the lesions the collagen bundles were infiltrated with mononuclear cells. Granular deposits of IgG, C′3, and C′4 were found at the dermoepidermal junction and around the superficial capillaries. The lesions healed completely and spontaneously within a year.
