The article presents a case study of a 21-year-old HIV-negative man diagnosed with pulmonary extensively drug-resistant tuberculosis (TB) discussing the use of drugs such as amikacin and moxifloxacin for treatment; the side effects during the treatment; and monitoring of patient for recurrence.

The article focuses on the initial response for polymerase chain reaction (PCR) assay being negative for the detection of mycobacterium ulcerans disease.

Background The incidence of cutaneous nontuberculous mycobacterial ( NTM) infection has increased in recent decades because of widespread use of immunosuppressive therapy and better detection methods. The histopathology of cutaneous NTM infection is not pathognomic and the organisms are slow and difficult to culture, making diagnosis challenging. Methods We reviewed the clinical and histopathological features of 13 cases of cutaneous NTM infection, and performed panmycobacterial polymerase chain reaction ( PCR) on the paraffin blocks. Results The immunocompetent patients presented with localized lesions on the extremities, whereas the immunocompromised patients presented with disseminated cutaneous lesions. The histopathology in immunocompetent patients was characterized by pseudoepitheliomatous epidermal hyperplasia, intraepithelial abscesses, transepidermal elimination and dermal granulomatous inflammation accompanied by necrosis and suppuration. The immunocompromised patients showed suppurative inflammation with little granuloma formation and numerous acid-fast bacilli. Paraffin block PCR was positive in 4 of 13 cases (31%), whereas culture was positive in 11 of 13 cases (85%). Conclusion The aforementioned histological features should help in diagnosing cutaneous NTM infection when combined with clinical and microbiological correlation. In our study, we did not find paraffin block PCR to be superior to conventional culture in detecting cutaneous NTM infection. [ABSTRACT FROM AUTHOR]
