Idiopathic eruptive macular pigmentation in a Chinese child

We present a case of a healthy 8-year-old boy who presented with disseminated asymptomatic brown macules on the face, neck, trunk, and proximal extremities for 3 months. Dermatologic examination revealed multiple, smooth, nonscaly, brown macules involving the face, neck, trunk, and proximal limbs. The Darier's sign was negative. Histopathologic study showed normal epidermis and basal membrane, and increasingly scattered melanophages in the papillary dermis. The final diagnosis was idiopathic eruptive macular pigmentation.
