Abstract
BackgroundEikenella corrodens and Streptococcus anginosus, which are primary colonization bacteria of the normal flora of the oropharynx, are infrequent bacteria, especially the former. Here, we report a case of lung abscess with a coinfection of Eikenella corrodens and Streptococcus anginosus in a lung cancer patient.Case presentationA 66-year-old Chinese man with lung cancer was admitted to the hospital, complaining of a cough and expectoration for five months and fever for two months. After a series of inspections to differentiate a cancer-related fever from an infectious fever, he was diagnosed with lung abscess. Draining pus culture demonstrated Eikenella corrodens and Streptococcus anginosus. After more than 1 month of antibiotic therapy and draining in total, he gradually recovered to fight against lung cancer.ConclusionThis report highlights the increased pathogenicity of Eikenella corrodens and Streptococcus anginosus in an immunocompromised cancer patient, especially after a few invasive operations. Additionally, even though a patient has been diagnosed with cancerous fever, strong vigilance is needed in case an infection arises.
