[Multiple granulomata pyogenica in a patient with acne vulgaris (author's transl)].

Multiple granulomata pyogenica are usually satellites of a primary lesion recently treated unsuccessfully. Disseminated pyogenic granulomas are very uncommon. In our case report, we describe a young man with six granulomata pyogenica over the chest, after treating his acne with tetracycline and vitamin A acid. In the discussion, we include infection, trauma and vitamin A acid as factors which can induce the vascular tumor in the region of a vascular dysplasia.
