Atypical mycobcterial injection abscess.

Other than suppurative organisms, atypical mycobacteria are also known to cause injection abscesses following vaccinations, injections, tattooing and even after implants. Though the usage of disposable needles is practised universally, sporadic cases do occur. The disease entity should be considered, while dealing with injection abscesses, to institute specific therapy. Acid-fast bacilli should be looked for in the pus and mycobacterial culture of the material from injection abscesses should be done for a definitive diagnosis.
