title: Spontaneous streptococcus pneumonia peritonitis in a patient with metastatic gastric cancer: a case report and etiologic consideration.
abstract: Spontaneous peritonitis in adults has not been previously reported to occur in association with ascites of neoplastic origin. We report a patient with metastatic gastric adenocarcinoma in whom spontaneous streptococcus pneumonia peritonitis occurred as a terminal event. Massive metastases may have resulted in significant loss of the hepatic reticuloendothelial system and impaired the capability of the liver to function as an effective bacterial filter, predisposing the patient to bacterial peritonitis.
