In this review, a case of an infected wound and brain abscess infected by bacteria from a patient with breast cancer is presented. CASE INTRODUCTION: The patient was a 42-year-old woman with a history of breast cancer and brain tumor, and the presence of Providencia bacteria and Sphingomonas in the breast wound and Staphylococcus epidermidis ( S. epidermidis ) in the cerebrospinal fluid (CSF) was diagnosed. The patient was treated with co-amoxiclav, clindamycin, ceftazidime/avibactam, metronidazole, imipenem/cilastatin, ceftazidime, vancomycin, and rifampin and was discharged with a stable and favorable general condition. The patient was treated with a breast wound infected with Providencia and Sphingomonas and a brain abscess infected with S. epidermidis . CONCLUSION: Due to the sensitivity of cancer patients to infections, it is important to choose appropriate antibiotics and follow up on these types of patients.
