We describe a case of <jats:italic>M. hominis<\/jats:italic> pneumonia in an immunocompetent man in his early 40s without any risk factors presenting with a cavitary lesion who developed empyema and necrotising pneumonia requiring surgical debridement. Identification of <jats:italic>M. hominis<\/jats:italic> and subsequent modification of antibiotic therapy led to favourable outcome. <jats:italic>M. hominis<\/jats:italic> should be considered in the differential diagnosis of patients with treatment resistant pneumonia especially in patients with trauma, intracranial injury, lung transplant or if immunocompromised. While <jats:italic>M. Hominis<\/jats:italic> is naturally resistant to all antibiotics that target cell wall synthesis, we recommend levofloxacin or other fluoroquinolone to most effectively treat with doxycycline as a potential alternative.<\/jats:p>","DOI":"10.1136\/bcr-2022-250107","type":"journal-article","created":{"date-parts":[[2023,6,20]],"date-time":"2023-06-20T13:15:17Z","timestamp":1687266917000},"page":"e250107","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["<i>Mycoplasma
