This 52-year-old man was operated 4 years before of a benign nevus of the lumbar area. The lesion was completely excised and pathologist concluded to a jentigo. 4 years after he consulted for this pigmentation appearing on two places of the scar. Dermoscopy revealed a faint pseudo-network of light-brown color with a moth-eaten border which was in favor of a scar lentigo. There were no signs of recurrence of a nevus or a melanoma. A follow-up was proposed.
