Gastrointestinal stromal tumor as entry port for S. intermedius causing bacteremia and multiple liver abscesses. Case report and review of literature.

We report a case of a previously healthy 52-year-old man who presented with fever and liver lesions suspicious for metastatic disease, which proved subsequently to be abscesses. Further workup revealed a gastrointestinal stromal tumor (GIST) in the gastric corpus as entry port to Streptococcus intermedius-associated bacteremia and liver abscesses. After antibiotic treatment and surgical resection of the tumor, the patient recovered well. This unusual case indicates that gastrointestinal stromal tumors can remain undetected until they cause a life threatening infection. A review of recent literature pertaining to GIST and liver abscesses follows.
