Uma ves\u00edcula (do latim vesicula<\/em> – ves\u00edcula) \u00e9 um elemento morfol\u00f3gico cavit\u00e1rio prim\u00e1rio de at\u00e9 0,5 cm de tamanho, que se eleva acima do n\u00edvel da pele e \u00e9 preenchido por l\u00edquido. O l\u00edquido (exsudado) pode ser seroso (transparente), turvo ou com uma mistura de sangue. <\/p>\n\n

A parede da ves\u00edcula \u00e9 chamada de “cobertura” e a cavidade interna \u00e9 chamada de c\u00e2mara.<\/p>\n\n

Etiologia e fisiopatologia<\/strong><\/h2>\n\n

As ves\u00edculas formam-se como resultado da delamina\u00e7\u00e3o da epiderme ou da separa\u00e7\u00e3o da epiderme da derme. As causas mais comuns s\u00e3o: <\/p>\n\n

    \n
  • Infec\u00e7\u00f5es virais:<\/strong> Herpes simplex, varicela, herpes zoster.<\/li>\n\n\n\n
  • Reac\u00e7\u00f5es al\u00e9rgicas:<\/strong> Eczema agudo, dermatite al\u00e9rgica.<\/li>\n<\/ul>\n\n

    Significado cl\u00ednico<\/strong><\/h2>\n\n

    Quando as ves\u00edculas se abrem (espontaneamente ou por co\u00e7ar), formam-se eros\u00f5es h\u00famidas, que s\u00e3o depois cobertas por crostas. A presen\u00e7a de ves\u00edculas agrupadas sobre um fundo eritematoso (avermelhado) \u00e9 um sinal cl\u00e1ssico de infe\u00e7\u00e3o herp\u00e9tica. <\/p>\n\n
