A 9-month-old girl was referred for a scalp naevus since birth. The baby girl was born full-term with an uneventful perinatal course. At birth, the scalp lesion was skin-coloured with no hair growth all along. There was a slight increase in pigmentation gradually and the size of the lesion increased in proportion with the head. Physical examination showed a 6 mm x 4 mm oval patch of alopecia on the right parietal scalp (Figure 1). The patch had a pinkish discolouration with central light blue-grey pigmentation. There were no abnormalities on cutaneous examination of the face, trunk and limbs.
