Infección de sitio de salida/túnel por *Mycobacterium fortuitum* relacionada con diálisis peritoneal en un paciente...

In patients in peritoneal dialysis (PD) who develop exit site and/or catheter tunnel infections, expeditious identification of the causative organism and early implementation of treatment are important to ensure good outcomes. Among the many causative organisms, the diagnosis of Mycobacterium fortuitum is particularly challenging, with its treatment often requiring a combination of approaches, including the removal of the peritoneal catheter and the administration of multiple antibiotics. Here, we present the case of a 25-month-old pediatric patient on PD who developed PD-associated tunnel infection due to M. fortuitum; the patient was successfully treated with multimodal antibiotics, with no sequela, following the rapid identification of the causative agent, the use of multimodal antibiotics, and PD catheter removal. In our case, the timely initiation of treatment, combined with ultrasound evaluation, was crucial for achieving a favorable outcome.
