Abstract
We report a case of hepatosplenic abscess caused by oral infectious pathogens. A 48-year-old man admitted for fever and abdominal pain and undergoning drainage of a hepatic abscess was referred to us for treatment of a coexisting splenic abscess. Many patients of hepatosplenic abscess are immunocompromised due to conditions such as leukemia or intensive chemotherapy. Reports of hepatosplenic abscesses in the absence of systemic disorders are rare. The patient's medical history was unremarkable. All of his teeth showed black pigmentation and were decayed. Typical oral infectious pathogen Streptococcus anginosus and a pigmented gram-negative anaerobic periodontal pathogen were isolated from abscesses. We conclude that the hepatosplenic abscesses in this case were caused by oral infectious pathogens. The relationship between oral hygiene and systemic diseases such as infectious endocarditis are well known, but no case of hepatosplenic abscess caused by oral infectious pathogens has, to our knowledge, been reported, thus far. Ultrasonography-guided drainage of the splenic abscess was conducted safely.
