Cuando aparece en forma de nódulo umbilical recibe el nombre clásico de nódulo de Villar. Su clínica típica consiste en una lesión nodular sobre cicatriz quirúrgica, de tamaño fluctuante, y sangrante en consonancia con el ciclo menstrual. La dermatoscopia puede variar desde la presencia de patrón vascular polimorfo sobre un fondo de color rojo lechoso o violáceo hasta la ausencia de estructuras vasculares en un fondo azulado con áreas marrones. En nuestro caso se observa un patrón no descrito hasta ahora, consistente en un retículo blanco central sobre fondo azulado que nos debería plantear como principal diagnóstico diferencial un dermatofibroma aneurismático, sin olvidar el nódulo de la hermana María José. El diagnóstico de confirmación requiere de estudio histopatológico y el tratamiento de elección es quirúrgico, con un pronóstico excelente.</p></span>" "pdfFichero" => "main.pdf" "tienePdf" => true "multimedia" => array:1 [ 0 => array:6 [ "identificador" => "fig0005" "etiqueta" => "Figura 1" "tipo" => "MULTIMEDIAFIGURA" "mostrarFloat" => true "mostrarDisplay" => false "figura" => array:1 [ 0 => array:4 [ "imagen" => "gr1.jpeg" "Alto" => 790 "Ancho" => 2092 "Tamanyo" => 160276 ] ] ] ] ] "idiomaDefecto" => "es" "url" => "/00017310/0000011200000002/v1_202102020721/S0001731020303768/v1_202102020721/es/main.assets" "Apartado" => array:4 [ "identificador" => "41021" "tipo" => "SECCION" "es" => array:2 [ "titulo" => "Imágenes en Dermatología" "idiomaDefecto" => true ] "idiomaDefecto" => "es" ] "PDF" => "https://static.elsevier.es/multimedia/00017310/0000011200000002/v1_202102020721/S0001731020303768/v1_202102020721/es/main.pdf?idApp=UINPBA000044&text.app=https://actasdermo.org/" "EPUB" => "https://multimedia.elsevier.es/PublicationsMultimediaV1/item/epub/S0001731020303768?idApp=UINPBA000044" ]
