This study aimed to evaluate the clinical microbial profile of patients with granulomatous lobular mastitis (GLM) and compare various detection methods to identify the most effective approach for pathogen detection, which could help enhance clinical diagnosis and treatment.We retrospectively analyzed data from 84 patients diagnosed with GLM, assessed the composition of pathogenic microorganisms in these patients, and compared the effectiveness of different sampling methods and detection techniques.Corynebacterium kroppenstedtii (C. kroppenstedtii) was identified as the predominant microorganism among G LM patients. The positivity rate was low in skin swabs (10%) but similar in pus (40%) and tissue samples (37%).After antibiotic treatment, the pathogen detection rate of metagenomic next-generation sequencing (mNGS) (54.5 5%) was found to be higher than that of culture-based methods (27.27%). Among the GLM cases with pathogeni c infection, although mNGS demonstrated higher sensitivity (75.0%) than culture tests (50.0%), both methods exhi bited 100.0% specificity. However, the time for obtaining results with mNGS was significantly shorter (1.2 ± 0.41 days) compared to bacterial culture (5.5 ± 0.64 days) (P < 0.05).Our findings indicate that pus was the most suitable sample type for microbial evidence collection in patients with GLM. mNGS demonstrated superior performance compared to culture in distinguishing infectious from non-i nfectious cases, with reduced antibiotic interference, faster turnaround time, and higher accuracy. Based on our sin gle-center experience, empirical cephalosporin treatment may be appropriate for these patients. Additionally, surgica l intervention remains the most efficient approach for rapid and complete resolution.
