Non-tuberculous mycobacteria encompass various Mycobacterium species, which are pathogens that can cause diverse cutaneous manifestations due to their ability to infect different tissues. These infections are increasingly recognised, particularly in immunocompromised individuals or those with predisposing factors like trauma, surgery, or environmental exposure. Non-tuberculous mycobacteria skin infections can present as ulcers, necrosis, nodules, sarcoidosis-like lesions, patchy alopecia, or limb oedema. In this case, we present a 37-year-old patient who had cutaneous involvement of the left breast.
