Infection cutanée aiguë et nécrosante à Mycobacterium marinum chez un patient traité par infliximab pour une maladie de Crohn

The worsening experienced by our patient 1 week after the beginning of the treatment is comparable with the immune reconstitution syndrome occasionally observed in tuberculosis in immunocompromised hosts, thus raising the question of the potential value of continuing infliximab treatment. Recommendations are needed concerning the prevention and treatment of M. marinum infections in patients on anti-TNFα biotherapies.
