Development of idiopathic eruptive macular pigmentation in an 11-year-old boy

A case of idiopathic eruptive macular pigmentation in a child demonstrates a variant of skin hyperpigmentation of uncertain etiology. We described an 11-year-old boy with light brown spots in the torso and limbs that developed against the background of normal skin without an established provoking factor. On examination, it was found that the disease had developed within one year. Initially, the process was localized to the elbow folds and axillary areas, but later the rash spread to the trunk, neck and extremities. No inflammatory changes were observed at the base of the rash elements. The patient was examined for the presence of diseases that could underlie the skin manifestations, and histological examination was performed to verify the diagnosis. The established diagnosis of idiopathic eruptive macular pigmentation made it possible to choose a wait-and-see approach in treating the patient, due to the available literature data on the self-resolution of this pathology and ineffectiveness of the available dermatosis treatment options.
