El prurigo nodular crónico se caracteriza por un ciclo de prurito y excoriación en el que intervienen mecanismos neurodérmicos, asociado a diversas enfermedades. Se manifiesta con placas o nódulos hiperqueratósicos cupuliformes. El tratamiento, enfocado en reducir el prurito, representa un desafío por la frecuente resistencia a las terapéuticas habituales. Se describe el caso de un hombre de 72 años, con antecedentes psiquiátricos, que presentó una dermatosis pruriginosa recalcitrante refractaria a múltiples esquemas de tratamiento.
