    • Abstract:
      Granular parakeratosis is a benign skin disease of unclear etiology which is considered an acquired disorder of keratinization with profilaggrin granules persisting in the stratum corneum. Clinically, it manifests with hyperkeratotic erythematous or brown or brownish papules which may coalesce into plaques with variable hyperpigmentation, located unilaterally or bilaterally in intertriginous areas with chronic irritation (axillary, inframammary, inguinal) or abdominal and lumbosacral areas mainly in areas with folds or occlusion. Itching is variable. Histologically, papillomatosis and acanthosis are found with a thickened parakeratotic stratum corneum and a large number of basophilic granules in the corneocytes. Most reports worldwide have been cases in adults and few cases in children, so we present a case of aranular parakeratosis in a child from Colombia, and a review of the literature.

    • Abstract:
      La paraqueratosis granulosa es una enfermedad cutánea benigna, de etiología poco clara. Se considera una alteración adquirida de la queratinización en la que persisten los gránulos de profilagrina en la capa córnea. Clínicamente se manifiesta con pápulas eritematosas o café parduscas con hiperqueratosis, las cuales pueden ser coalescentes,y formar placas con hiperpigmentación variable, ser de presentación unilateral o bilateral, localizadas en áreas intertriginosas con irritación crónica (región axilar, inframamaria, inguinal), en el área abdominal y lumbosacra, principalmente en los pliegues o zonas con oclusión. El prurito se encuentra asociado en forma variable. En el estudio histopatológico se ha demostrado papilomatosis y acantosis, con un estrato córneo paraqueratósico engrosado y numerosos gránulos basófilos en los corneocitos. La mayoría de reportes a nivel mundial han sido de casos en adultos y pocos reportes en niños, por lo que se presenta un caso de paraqueratosis granulosa en un niño colombiano y se hace una revisión del tema.
