Phlegmonous gastritis associated with invasive Pseudomonas aeruginosa infection.

We report the case of a 49 years-old female that was hospitalized due to a recent diagnosis of acute lymphoblastic leukemia. As a consequence of induction chemotherapy (CALGB 10403 scheme), she developed severe neutropenia (0.04 10^3/ul).
