O carb\u00fanculo \u00e9 uma inflama\u00e7\u00e3o aguda purulenta e necr\u00f3tica que afeta um grupo de fol\u00edculos pilosos e gl\u00e2ndulas seb\u00e1ceas adjacentes. O processo \u00e9 caracterizado pela forma\u00e7\u00e3o de um infiltrado extenso e profundo na pele e no tecido subcut\u00e2neo, seguido de necrose e rejei\u00e7\u00e3o do tecido.<\/p>\n\n

Essencialmente, um carb\u00fanculo \u00e9 uma forma mais grave e comum de fur\u00fanculo (p\u00fastula). Ao contr\u00e1rio do fur\u00fanculo, que tem um \u00fanico n\u00facleo purulento, o carb\u00fanculo forma v\u00e1rios focos purulentos e necr\u00f3ticos que se fundem num \u00fanico conglomerado.<\/p>\n\n

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

O agente patog\u00e9nico mais comum \u00e9 o Staphylococcus aureus.<\/em>. A infec\u00e7\u00e3o penetra em v\u00e1rios fol\u00edculos pilosos adjacentes, causando inflama\u00e7\u00e3o difusa. O processo se espalha rapidamente em profundidade e extens\u00e3o, atingindo a derme e tecido adiposo subcut\u00e2neo.<\/p>\n\n

Patologicamente, o carb\u00fanculo \u00e9 caracterizado pela trombose dos vasos que irrigam a \u00e1rea afetada, levando \u00e0 necrose (morte) extensa dos tecidos. Formam-se v\u00e1rias aberturas no centro do infiltrado, atrav\u00e9s das quais \u00e9 libertado pus espesso e esverdeado.<\/p>\n\n

Signific\u00e2ncia cl\u00ednica<\/strong><\/h2>\n\n

Clinicamente, o carb\u00fanculo \u00e9 um infiltrado grande, denso e extremamente doloroso, de cor p\u00farpura-azulada. O seu desenvolvimento \u00e9 acompanhado por sintomas pronunciados de intoxica\u00e7\u00e3o geral: febre alta, calafrios, fraqueza. A localiza\u00e7\u00e3o mais perigosa \u00e9 o rosto (l\u00e1bio superior, nariz), devido ao risco de dissemina\u00e7\u00e3o da infe\u00e7\u00e3o para a cavidade craniana (trombose do seio cavernoso).<\/p>\n\n

O tratamento do carb\u00fanculo, ao contr\u00e1rio da maioria dos fur\u00fanculos, \u00e9 geralmente cir\u00fargico. Consiste numa ampla incis\u00e3o em cruz no infiltrado, remo\u00e7\u00e3o de todos os tecidos necr\u00f3ticos para assegurar um escoamento eficaz do conte\u00fado purulento. A cirurgia \u00e9 sempre acompanhada de antibioterapia sist\u00e9mica. As tentativas de extrair um carb\u00fanculo por conta pr\u00f3pria s\u00e3o estritamente proibidas devido ao elevado risco de propaga\u00e7\u00e3o da infe\u00e7\u00e3o.<\/p>\n","protected":false},"excerpt":{"rendered":"
