A one-month-old boy of this disease was reported. Large, indurated plaques were disseminated symmetrically over the buttock, lumbar region, and flexor aspects of thighs. Nodules, from 2 to 5 cm in diameter, were noticed on the right infraauricular region, extensor surfaces of the upper extremities, and flexor aspects of the lower legs. They disappeared 5 months later spontaneously

The boy, who weighed 4,760 gr at birth, was born in asphyxia and had hematoma on the scalp.
