Lentigines in resolving psoriatic plaques: rarely reported sequelae in pediatric cases.
Lentigo formation has been described in adults after the resolution of psoriatic plaques treated with various standard psoriasis treatments. We describe three cases of lentigines developing in areas of resolving psoriatic plaques: two in patients treated with etanercept and one before starting etanercept. A possible pathomechanism is proposed.
