<\/span>\nHistologie<\/span> angiofibrome<\/span><\/h2>\nLes angiofibromes provoquent une masse en forme de d\u00f4me \u00e0 la surface derme<\/span> (Figure 1).

Les blessure<\/span> se caract\u00e9rise par un prolif\u00e9ration<\/span> de cellules \u00e9toil\u00e9es et en spirale autour vaisseaux sanguins<\/span> (Figure 2). Il y a une \u00e9paisseur concentrique collag\u00e8ne<\/span> colis (figures 1, 2). La comparaison de la densit\u00e9 de collag\u00e8ne de la l\u00e9sion avec le derme environnant, qui devrait \u00eatre plus l\u00e2che ou endommag\u00e9 \u00e9lastiquement, peut \u00eatre un indice de diagnostic utile.
