RESUMO
Abstract We report a case of Mycobacterium abscessus subsp. bolletii colonization in upper respiratory tract of an immunocompetent patient, who was misdiagnosed as tuberculosis by Acid Fast Bacilli (AFB) and cord factor formation observed directly from the sputa culture in liquid medium. This fact reflected a significant impact on the individual case's life and showed the importance to identify the mycobacteria isolated from clinical sample at species level, and to determine the true implication of nontuberculous mycobacteria (NTM) detected in clinical samples.

Relatamos um caso de tuberculose cutânea do tipo eritema indurado de Bazin em paciente do sexo feminino, 26 anos de idade, com presença de úlceras e nódulos infiltrados, eritêmato- ferruginosos, com áreas de supuração e de aspecto endurecido em região de membro inferior esquerdo. O diagnóstico foi feito por meio da detecção de DNA micobacteriano nas lesões cutâneas por meio do método de reação em cadeia da polimerase. Realizou-se tratamento com pirazinamida, rifampicina, isoniazida e etambutol, obtendo-se melhora clínica e resolução das lesões cutâneas da paciente.(AU)
We report a clinical case of Erythema Induratum of Bazin cutaneous tuberculosis on a 26-year-old female patient that presented with ulcers and erythematous-ferruginous infiltrated nodules, with hardened suppuration areas on left lower limb. Diagnosis was made through mycobacterian DNA detection on cutaneous lesions using the chain polymerase reaction method. The treatment was carried out with Pyrazinamide, Rifampicin, Isoniazid and ethambutol, which provided clinical improvement and resolution of the patient's cutaneous lesions.(AU)
