RATIONALE: Fulminant macrolide-resistant Mycoplasma pneumoniae pneumonia (MPP) has seldom been reported, and cases of MPP usually show rapid improvement after fluoroquinolones or tetracyclines addition. The purpose of this case report is to highlight the importance of proper selection of antibiotics for treatment of severe MPP and increase awareness concerning the emergence of fluoroquinolone-resistant MPP. PATIENT CONCERNS: A case of severe life-threatening pneumonia in a 26-year-old man with high fever and cough was non-responsive to azithromycin and fluoroquinolones. DIAGNOSES: The patient was diagnosed with MPP based on the test results of bronchoalveolar lavage using real-time quantitative PCR method. INTERVENTIONS: Tigecycline was given to the patient after azithromycin and fluoroquinolones failed. OUTCOMES: The patients fever subsided within the first day of tigecycline therapy. He showed rapid symptom resolution and improvement in lung infiltration after 4 days of tigecycline therapy. LESSONS: The case suggests that fulminant MPP should be timely treated with proper antibiotics, and the possible emergence of fluoroquinolone-resistant MPP should be of concern.
