title: A Rare Case of Sarcina ventriculi of the Stomach in an Asymptomatic Patient.
abstract: Sarcina ventriculi is a gram-positive coccus that grows in a tetrad arrangement in the stomach. In the past 35 years, less than 20 cases have been reported in the literature, and it has been associated with life-threatening complications such as emphysematous gastritis and perforation. Treatment of S ventriculi generally consists of proton pump inhibitors with or without adjuvant antibiotic therapy. We report the first ever case of S ventriculi, including the morphological and immunohistochemical features, occurring in an asymptomatic patient with a history of Helicobacter pylori gastric ulcers.
