Background Peritoneal dialysis (PD)-associated peritonitis caused by nontuberculous Mycobacterium is rare; however, the number of cases has increased over the past decades. Mycobacteroides massiliense is a subspecies of the Mycobacteroides abscessus complex. It has different clinical characteristics compared to the other subspecies of the complex. Previous case reports of PD-associated peritonitis caused by Mycobacteroides abscessus complex have not distinguished the subspecies in detail. Case presentation A 40-year-old man presented with an exit-site and tunnel infection refractory to antibiotic therapy. Peritonitis occurred after simultaneous catheter removal and reinsertion. The Mycobacteroides abscessus complex was detected in the culture of the dialysis effluent. Removal of the PD catheter combined with antibiotics, including macrolides, resulted in a good clinical course. Further analysis of multiplex PCR and the hsp65 gene sequence identified the bacterium as Mycobacteroides massiliense. Conclusions The Mycobacteroides abscessus complex is classified into three subspecies; Mycobacteroides abscessus, Mycobacteroides massiliense, and Mycobacteroides bolletii. These have different characteristics, particularly antibiotic susceptibility. Therefore, clear identification of the subspecies of the Mycobacteroides abscessus complex is necessary for definitive treatment.
