Molluscum contagiosum infection on a congenital intermediate melanocytic naevus

摘要

A 2-year-old girl presented with a 3-month history of several small painless papules, growing on the surface of an abdominal congenital melanocytic naevus (MN).Her mother noted that the lesions were significantly increasing in number and size. There was no history of trauma and her medical and family histories were unremarkable.Physical examination revealed multiple skin-coloured, translucent, glossy, dome-shaped papules, ranging from 1 to 3 mm, localised exclusively on the surface of a macular, smooth, light to dark brown, non-hypertrichotic congenital intermediate MN (2 x 4 cm) (see figure 1).
