Non Tuberculous Mycobacteria (NTM) is a diverse group of acidfast bacilli in genus Mycobacteria that include more than 100 different species. About one-third of NTM species have been associated with human disease and of all the species under this group,Mycobacterium fortuitum , abscessus and chelonae have been most frequently and are being increasingly associated with skin and soft tissue infections after skin injury following inoculation, minor trauma or surgery.
Mycobacterium abscessus was described first by Moore and Frerichs in 1953. In the beginning M. abscessus was classified as subspecies of chelonae but with the help of DNA homology studies, this has been classified as a separate species. M. abscessus has been further classified into three closely related species; M. abscessus , M. massiliense and M. bolletii on the basis of RNA Polymerase B sequencing pattern. However little is known regarding the clinical impact of this species differentiation. M. abscessus is considered one of the most pathogenic and drug resistant NTM. We report a case of young child with generalized cutaneous lesions due to M. abscessus following cardiac surgery.
