Peritonitis remains an important complication of peritoneal dialysis and is mostly caused by aerobic enteric bacteria. Non-tuberculous mycobacteria (NTM)-associated peritonitis is an unusual but serious infection, requiring special culture techniques to avoid delay in diagnosis. We report the case of an 11-year-old girl with aplastic anemia on ambulatory peritoneal dialysis who had Mycobacterium avium complex-associated peritonitis after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This case emphasizes that we should be constantly cautious about NTM infection in allo-HSCT recipients, especially when standard cultures are negative and the infection is refractory to empirical antibiotic therapy.
