Bacteremia from Streptococcus constellatus revealing a Gastro-Intestinal Stromal Tumor

Abstract

Background. Pyogenic Liver Abscesses (PLA) are the most common type of visceral abscess. They generally develop in a context of biliary disease or hematogenous seeding, but a complete diagnostic work-up is always required in order not to miss other important causes, including above all malignancies of the gastro-intestinal tract. Case presentation. Herein, we report a particular case of a 80 years-old immunocompetent woman hospitalized for sepsis. At the end of the diagnostic process, Streptococcus constellatus(Sc) was identified as the cause of sepsis, multiple PLA were found together with a previous unknown ileal malignancy. We speculated about a possible correlation among these three entities (i.e. sepsis from Sc, PLA and tumors). Conclusions. Detection of Streptococcus constellatus in blood should raise red flags in clinicians as aggressive clinical presentation are possible.
