Lung cancer complicated with Nocardiopsisdassonvillei pulmonary infection:a case report
Nocardia is a rare opportunistic pathogen.The number of reported cases of infections caused by this bacterium is increasing,associated with the rising prevalence of organ transplantation,cancer,as well as improvements in clinical diagnostics and laboratory techniques.However,pulmonary infections caused by Nocardia Darsonwierii are rarely reported.Lung cancer combined with Nocardia Darsonwierii pulmonary infec-tion is even more uncommon.Due to its nonspecific clinical manifestations and imaging features,and the diffi-culty in culturing the bacterium,such infections are prone to being overlooked or misdiagnosed,and the prognosis for affected patients is often poor.The First Affiliated Hospital of Dali University treated a patient with lung cancer and a concurrent Nocardia Darsonwierii pulmonary infection.The patient's condition improved following chemotherapy combined with antimicrobial treatment using sulfamethoxazole/trimethoprim and moxifloxacin.A review of relevant literature was conducted to enhance clinical awareness of this condition.
