摘要

Background

Mycobacterium abscessus (M. abscessus) infection following breast augmentation is a rare complication, yet evidence and standardized treatments remain limited. Challenges include diagnostic difficulties and prolonged treatment periods.

Methods

We report two cases of M. abscessus infection following breast augmentation and conducted a structured narrative review of PubMed literature to explore prevention, diagnosis, and treatment strategies associated with this condition.

Results

The two patients underwent different breast augmentation procedures: one received autologous fat transfer, and the other had a prosthetic implant inserted. Following confirmation of M. abscessus infection via metagenomic next-generation sequencing (mNGS), both patients underwent through surgical debridement and drainage with daily amikacin irrigation. Combination antibiotic therapy was administered, including intravenous amikacin and linezolid, plus oral azithromycin. Both patients demonstrated good tolerance to the prescribed antibiotics, achieving effective infection control without recurrence over a 12-month follow-up period. The rigorous debridement and targeted antibiotic therapy significantly enhanced treatment efficacy.

Conclusion

This study reports two rare cases of M. abscessus infection occurring after breast aesthetic surgery. Such infections are difficult to diagnose and are often associated with prolonged treatment courses. We successfully identified the causative pathogen through mNGS and implemented a comprehensive treatment strategy that included multiple surgical debridements, local irrigation, and combination antimicrobial therapy with azithromycin, amikacin, and linezolid, which was associated with favorable clinical outcomes. Rather than establishing a definitive management model, this study provides practical, case-based insights into the diagnosis and management of postoperative M. abscessus infections.
