The Mycobacterium abscessus complex, a part of the nontuberculous mycobacteria (NTM) group, comprises three subspecies: M. abscessus subsp. abscessus, M. abscessus subsp. massiliense, and M. abscessus subsp. boletii11.

Open Forum Infect Dis. 2018;5(2):ofy022.. This study was approved by the Institutional Ethics Committee. A 38-year-old woman presented with painful inflammatory nodules 2 months after receiving injections of lipolytic enzymes into her abdominal fat (Figure 1). The nodules were tender, and the patient reported pus drainage. Despite a 7-day course of cephalexin and moxifloxacin, her condition did not improve. Azithromycin 500 mg and ciprofloxacin 500 mg daily was initiated. The direct acid-fast bacilli (AFB) examination yielded negative, and the histopathological examination revealed deep granulomatous chronic dermatitis with granulation tissue, without evidence of AFB or fungi (Figure 2). However, a culture of the fragment in Lowenstein-Jensen medium and Mycobacteria Growth Indicator Tube broth with automated fluorimetry detected mycobacteria. M. abscessus subsp. abscessus was identified through partial sequencing of the rpoB gene and further analyzed by the GenBank international database. After maintaining the azithromycin for 6 months, the lesions resolved leaving scars (Figure 3). The growing interest in aesthetic procedures has led to a significant increase in NTM infections, making them an emerging public health issue. Such procedures should be performed by qualified medical professionals using aseptic techniques and materials. Public health strategies are needed to prevent morbidity and mortality, and it is crucial to educate the public about these risks.
