title: [A case of liver abscess due to Streptococcus anginosus infection secondary to a dental extraction].
abstract: A 74-year-old man was referred to our hospital because of a high fever. He had undergone a dental extraction about 1 month prior to admission because of apical periodontitis. Imaging study revealed liver abscess lesions. Infection with Streptococcus anginosus was confirmed using both stab and blood culture. An adequate selection of antibiotics was administered, and a good outcome was obtained. There have been no case reports of liver abscess caused by intraoral commensal flora related to dental extraction in healthy adults. This case shows that liver abscesses can occur secondary to dental extractions, even in healthy adults.
