RESUMEN
La papulosis fibrosa blanca del cuello es una patología benigna, que se presenta frecuentemente en personas mayores y que se caracteriza por pápulas blanquecinas ubicadas habitualmente en las regiones laterales del cuello. El hallazgo histopatológico distintivo es el incremento de las fibras de colágeno en la dermis papilar. Su etiopatogenia es, hasta ahora, desconocida y su tratamiento es difícil. Dado que corresponde a una patología infrecuente, probablemente subdiagnosticada, es que se decide reportar el caso de una mujer chilena de 77 años.
