Abstract
Mycoplasma hominis, commonly residing in the genitourinary tract, can cause rare extragenital infections, especially in immunocompromised individuals. This report details a case of chronic osteomyelitis with a pathological femur fracture in a 79-year-old woman. Despite a history of bone tuberculosis, the infection was identified as Mycoplasma hominis through culture and mass spectrometry, highlighting the diagnostic challenges due to the organism's lack of a cell wall. This case underscores the necessity for advanced diagnostic methods and awareness of Mycoplasma hominis in non-urogenital infections.
