Esse fenômeno, também denominado “reação reversa”, ocorre na forma borderline (dimorfa) da hanseníase e está associado a um aumento da imunidade mediada por células. Ela ocorre normalmente nos primeiros 6 meses de tratamento em pacientes não tratadas anteriormente, mas pode estar relacionada a estresse, infecções intercorrentes ou gravidez. As características clínicas incluem edema inflamatório, eritema e, ocasionalmente, ulceração de lesões existentes, sintomas constitucionais e neurite. Se a neurite não for tratada imediatamente, pode ocorrer dano permanente ao nervo motor. | |||
