[Persistent grayish pigmentation in a child].

The patient was a 7-year-old child of gypsy origin, with no relevant personal history, who presented with progressively developing, asymptomatic, hyperpigmented lesions, first observed 11 months earlier. The lesions had started to appear on the upper part of the trunk and had shown a centrifugal progression, becoming generalized over the course of a few months. No triggering event was identified. The mother had observed that, having reached their maximum development, the lesions were slowly fading.
