Core Tip

Core Tip: We reported a case of phlegmonous gastritis due to Bacillus cereus infection during the neutropenic phase after consolidation chemotherapy for acute lymphocytic leukemia. Including our 2 patients, we analyzed 7 similar patients reported in the past. Histopathological examination with gastric biopsy was performed only in our two patients, and in both cases, characteristic findings that should be called "neutropenic necrotizing gastritis" were observed.
