title: Documented evolution of a solar lentigo into a solitary lichen planus-like keratosis.
abstract: The purpose of this communication is to report the evolution of a solar (senile) lentigo into a solitary lichen planus-like keratosis (SLPLK). This case is unique because this evolution was documented by biopsies taken from the same lesion nearly 5 years apart. The pathogenesis of SLPLK is discussed.
