We report a 72-year-old man on haemodialysis who presented with multiple ab
scesses on his lower legs. Routine bacterial culture of abscess pus was rep
orted as 'sterile' after 48 h. leading to the suspicion of a mycobacterial
infection. Skin biopsy taken for mycobacterial microscopy and culture isola
ted a heavy growth of Mycobacterium abscessus.
