A 48-year-old man was admitted to our hospital with osteomyelitis of his right thumb. His symptoms had started 1 month previously, 1 week after getting his right thumb caught in a door. MRI showed osteomyelitis of the distal phalanx of the right thumb. Debridement was performed and mycobacteria were isolated from the specimen one week after the culture was started. The mycobacterium was confirmed to be Mycobacterium goodii by 16S rRNA sequencing and an antibiotic susceptibility test. After debridement, treatment with clarithromycin, levofloxacin and amikacin was initiated empirically. According to the susceptibility test and adverse effect of antibiotics, we changed them to levofloxacin and trimethoprim-sulfamethoxazole. The antimicrobial treatment for 9 months resulted in successful resolution of the osteomyelitis.

To our knowledge, this is the first reported case of osteomyelitis caused by Mycobacterium goodii in Japan. Clinicians should consider this organism as a causative agent when treating patients with post-traumatic osteomyelitis.
