Une papule (du latin papula<\/em> – bouton) est un \u00e9l\u00e9ment superficiel primaire, d\u00e9pourvu de cellules, d’une \u00e9ruption cutan\u00e9e qui s’\u00e9l\u00e8ve au-dessus du niveau de la peau. Une papule a une consistance dense ou molle et, contrairement \u00e0 une tache, peut \u00eatre palp\u00e9e clairement. <\/p>\n\n

Les papules sont g\u00e9n\u00e9ralement d\u00e9finies comme des \u00e9l\u00e9ments dont le diam\u00e8tre ne d\u00e9passe pas 0,5 cm (jusqu’\u00e0 1 cm dans certaines classifications). La papule ne laisse souvent pas de cicatrice pendant le processus d’inversion, mais peut laisser une pigmentation temporaire. <\/p>\n\n

\u00c9tiologie et physiopathologie<\/strong><\/h2>\n\n

L’\u00e9l\u00e9vation des tissus peut \u00eatre caus\u00e9e par <\/p>\n\n

    \n
  • Infiltration cellulaire :<\/strong> accumulation de cellules inflammatoires dans le derme (par exemple dans le psoriasis ou le lichen plan squameux rouge). <\/li>\n\n\n\n
  • Hypertrophie tissulaire :<\/strong> croissance excessive de l’\u00e9piderme (verrues). <\/li>\n\n\n\n
  • D\u00e9p\u00f4t de produits m\u00e9taboliques :<\/strong> par exemple, xanthomes dans les troubles du m\u00e9tabolisme des lipides.<\/li>\n<\/ul>\n\n

    Aspects du diagnostic diff\u00e9rentiel<\/strong><\/h2>\n\n

    Les papules peuvent fusionner pour former des \u00e9l\u00e9ments plus grands, les plaques. Il est important de distinguer une papule d’une v\u00e9sicule (qui contient du liquide) et d’un nodule (qui est plus profond et plus grand). <\/p>\n","protected":false},"excerpt":{"rendered":"
