A 15-month-old girl presented with a 14-month history of 2 dark plaques on her thigh. The lesions had gradually increased in size but had remained asymptomatic. The prenatal and postnatal personal and family medical histories were noncontributory.
Physical examination revealed an area approximately 4 cm in diameter on the anterior aspect of the thigh, with clusters of orifices that were plugged with dark material (Figure 1). The findings of the rest of the physical examination were normal; specifically, there were no other cutaneous lesions or skeletal or ocular abnormalities.
