Bouba secundária resulta da disseminação linfática e hematogênica de espiroquetas do Treponema pallidum subespécie pertenue a partir do local inicial da inoculação e aparece de algumas semanas a 2 anos após a infecção primária. Os sintomas iniciais mais comuns são inespecíficos e incluem artralgia e mal-estar. As lesões cutâneas secundárias consistem em múltiplas pápulas e nódulos semelhantes à lesão inicial, mas menores. Elas podem ser localizadas, regionais ou generalizadas; podem ulcerar e em áreas úmidas podem mimetizar condiloma plano sifilítico. Placas hiperceratóticas nas palmas das mãos e plantas dos pés podem desenvolver fissuras dolorosas e infecção secundária, resultando em uma marcha característica "semelhante a um caranguejo" | |||
