Una bulla (del lat\u00edn bulla<\/em>) es una cavidad primaria grande (m\u00e1s de 0,5-1 cm de di\u00e1metro) llena de l\u00edquido. Es esencialmente una \u00abgran ves\u00edcula\u00bb. Las bullas pueden localizarse intraepid\u00e9rmicamente (en la epidermis) o subepid\u00e9rmicamente (bajo la epidermis). <\/p>\n\n

La \u00abcubierta\u00bb de la vejiga puede estar tensa o fl\u00e1cida.<\/p>\n\n

Etiolog\u00eda y fisiopatolog\u00eda<\/strong><\/h2>\n\n

Las causas de la formaci\u00f3n de ampollas suelen estar asociadas a procesos patol\u00f3gicos graves: <\/p>\n\n

    \n
  • Factores mec\u00e1nicos:<\/strong> Fricci\u00f3n (callosidades). <\/li>\n\n\n\n
  • Factores t\u00e9rmicos:<\/strong> Quemaduras de segundo grado. <\/li>\n\n\n\n
  • Enfermedades autoinmunes:<\/strong> Ves\u00edculas vesiculares (acant\u00f3lisis – p\u00e9rdida de conexi\u00f3n entre las c\u00e9lulas epid\u00e9rmicas), penfigoide ampolloso. <\/li>\n\n\n\n
  • Reacciones t\u00f3xico-al\u00e9rgicas:<\/strong> S\u00edndrome de Lyell.<\/li>\n<\/ul>\n\n

    Importancia cl\u00ednica<\/strong><\/h2>\n\n

    La presencia de ampollas suele indicar la gravedad de la lesi\u00f3n cut\u00e1nea. Cuando la ampolla se rompe, se forma una gran superficie erosiva, que es una puerta de entrada para la infecci\u00f3n y provoca una p\u00e9rdida importante de l\u00edquido corporal y prote\u00ednas. <\/p>\n","protected":false},"excerpt":{"rendered":"
