Skin infection by Mycobacterium farcinogenes-senegalense group in an immunocompetent patient: a case report.

Background: Mycobacterium farcinogenes-senegalense group mostly cause bovine farcy, which rarely infect human beings. We reported one case of cutaneous Mycobacterium farcinogenes-senegalense group infection in an immunocompetent victim.
Case Presentation: A 66-year-old Taiwanese woman with hypertension developed tender nodules on her left dorsal foot for 2 months. Tissue culture identified Mycobacterium farcinogenes-senegalense group. The lesion was treated successfully with clarithromycin and sulfamethoxazole/trimethoprim, followed by surgical excision.
Conclusions: Mycobacterium farcinogenes-senegalense group infection should be considered as a potential pathogen of skin infection in immunocompetent patients.
