[Multiple eccrine spiradenomas in a linear nevoid pattern]

A 16-year-old boy presenting with multiple slightly painful, bluish red papules and plaques on the left thorax is reported. The skin lesions were arranged in a linear and arched pattern following the lines of Blaschko. Clinical examination led to the suspicion of multiple leiomyomas, syringomas or glomus tumours. Histological examination revealed that the lesions were typical benign eccrine spiradenomas.
