An 8-year-old boy was first observed for the presence of asymptomatic dark spots of the trunk suddenly arisen from 6 months. The family history was negative for similar lesions. There were not diseases worthy of note in the personal history and the child had not taken drugs in the previous three months. The mother incidentally noted the spots that were brownish from their onset and had not been preceded by inflammatory or other type lesions. The physical examination showed about forty 1-3 cm in diameter spots, of brown color, with clear-cut margins, some vertical in the dorsal paramedian region, others oblique in the costal region (Fig. 1, 2). Dermoscopy showed a homogeneous pigmentation. The rubbing of a stain of the trunk (Fig. 2, circled) evoked a mild erythema without wheal. These data led to the final diagnosis of idiopathic eruptive macular pigmentation. The boy did not receive any treatment, but we informed the parents that the lesions would regress spontaneously in months or years.
