Abstract
Edwardsiella tarda causes enterocolitis, which does not need to be treated in many cases. However, in immunocompromised hosts, the disease becomes severe resulting in soft tissue abscess. In such cases, removal of the lesion is required at an early stage. An 83-year-old woman presented to the emergency department with a chief complaint of fever, which was initially treatment as complex urinary tract infection. Further evaluation revealed she had E. tarda sepsis and that the bacteria was highly likely to originate from an abscess of the uterine adnexa. Because we thought a complex surgery was necessary, we transferred her to a regional core hospital. However, she recovered with only administration of antibacterial agents at that hospital.Then, 1 year and 4 months later, she was admitted to our hospital again. We made a diagnosis of disease recurrence. She did not improve with antibacterial therapy this time, so she was transferred to the other regional core hospital and underwent surgery. Histological examination revealed an appendiceal carcinoma in the abscess lesion. This case suggests that when E. tarda bacteremia is diagnosed, its focus and the root cause should be investigated.
