Cutaneous infection with rapidly growing mycobacteria is uncommon and
diagnosis may be difficult. However, the histopathological features ar
e distinctive and may aid diagnosis, The three pathogenic species, Myc
obacterium fortuitum, M. chelonae and M. abscessus, show major differe
nces in their antimicrobial sensitivities, and species identification
is therefore important. We describe a case of infection with M. absces
sus, and discuss the clinical and pathological features of such infect
ions, and approaches to their treatment.
