Nontuberculosis Mycobacteria Infection After Liposuction and Fat Grafting for Augmentation Mammoplasty: A Case Report and Literature Review.

BACKGROUND

Nontuberculosis mycobacteria (NTM) commonly occur in nature. Although the infection rate is low, soft tissue infection with NTM after surgical procedures is possible in both immunocompromised and normal populations. For cosmetic surgery, NTM infection has emerged as a common infection in the recent years, and this indicates the need to pay more attention, especially to those with prolonged atypical uncertain wound problems.

AIM AND OBJECTIVES

We aimed to report a case of NTM infection after breast augmentation to share our experience on clinical appearance and process of diagnosis and treatment, and to review the existing literature.

MATERIALS AND METHODS

We retrospectively review a patient who suffered from NTM infection after liposuction and fat grafting for breast augmentation between 2019 and 2021 in our hospital. The baseline characteristics, operations, bacterial culture report, medications, and outpatient information were collected from medical records.

RESULTS

The patient suffered from purulent skin lesions after breast augmentation and was diagnosed with NTM infection according to the culture report. The NTM infection was resolved after a long-term course of treatment for around a year, including surgical debridement, serial aspirations, and prescriptions of antituberculosis medications.

CONCLUSIONS

The results of our study suggest that NTM must be considered when facing refractory infections after surgeries or invasive procedures without bacterial growth on routine cultures. Acid-fast stain and mycobacterial culture are strongly recommended. Treatment modalities include localized aspiration, surgical debridement, and multidrug antibiotics based on the sensitivity of the microorganism.
