Definition: Chronic active gastritis is the inflammation of the stomach characterized by the simultaneous presence of a mononuclear cell infiltrate and neutrophilic polymorphonuclear inflammation.
Because this term may convey an entity (like chronic active hepatitis) rather than a phase of a single disease, it is preferable to use the term active as a descriptor, as in the original Sydney System (e.g., chronic gastritis, active).
