Summary

Tuberculosis is a serious infection that is increasing in prevalence, affecting many people worldwide. The diagnosis of cutaneous tuberculosis is challenging and requires the correlation of clinical findings with often inconclusive diagnostic testing. Extrapulmonary tuberculosis comprises approximately 10% of all cases of tuberculosis, and cutaneous tuberculosis makes up only a small proportion of these cases. Discussed here is the case of a 61-year-old immunocompetent female with a large cutaneous lesion on her index finger secondary to Mycobacterium tuberculosis. Tissue cultures taken at biopsy were negative; however, empiric antimycobacterial therapy was initiated. The initial regimen was not tolerated, and antituberculous therapy was substituted for moxifloxacin and clarithromycin. The lesion improved significantly with a concurrent improvement in function.
