Journal Title: Nasza Dermatologia Online - Year 2018, Vol 9, Issue 2
Abstract
We present the case of a 63-year-old woman with a one-year history of punctiform, hyperkeratotic lesions on the palms of both hands. The histologic examination showed the presence of a cornoid lamella and allowed the establishment of the diagnosis of punctate porkeratosis. Porokeratosis is a clonal disorder of keratinization that exhibits multiple forms of presentation, with punctate porokeratosis being an infrequent form. The differential diagnosis of palmo-plantar punctiform, hyperkeratotic lesions is composed of porokeratosis punctata, the spiny keratodermas, other punctate keratodermas, and other pathologies with distinctive characteristics. In the review of literature of this article we have focused on explaining and clarifying the historical problem concerning the terminology used for these pathologies. Presentamos el caso de una paciente de 63 años con lesiones puntiformes hiperqueratósicas de un 1 año de evolución en palmas de ambas manos. El estudio histológico demostró la presencia de una lámina cornoide y permitió establecer el diagnóstico de poroqueratosis punctata. La poroqueratosis es un desorden clonal de la queratinización que exhibe múltiples formas de presentación, siendo la variante punctata una forma infrecuente. El diagnóstico diferencial de lesiones puntiformes hiperqueratósicas palmo-plantares está compuesto por la poroqueratosis punctata, las queratodermias espinosas, otras queratodermias punctatas y otras patologías de características distintivas. En la revisión del presente reporte nos hemos enfocado en exponer y clarificar la histórica problemática que ha existido en la terminología empleada para estas patologías.
