Presentamos el caso de una paciente de 79 años con lesiones pigmentadas simétricas en áreas fotoexpuestas de la cara y manos. La dermatoscopia evidenció puntos periféricos (&#8220;trail tracks&#8221;) y aclaramiento central, mientras que la biopsia confirmó la presencia de la lámina cornoide característica. Se revisa la clínica, dermatoscopia, hallazgos histopatológicos, factores etiológicos, variantes y opciones terapéuticas, destacando la importancia del diagnóstico temprano, la fotoprotección y la vigilancia periódica por riesgo de transformación maligna.]]></p></abstract>
