Answer

Infection of the endometrium, or decidua, usually results from an ascending infection from the lower genital tract. From a pathologic perspective, endometritis can be classified as acute versus chronic. Acute endometritis is characterized by the presence of neutrophils within the endometrial glands. Chronic endometritis is characterized by the presence of plasma cells and lymphocytes within the endometrial stroma.

In the nonobstetric population, pelvic inflammatory disease and invasive gynecologic procedures are the most common precursors to acute endometritis. In the obstetric population, postpartum infection is the most common predecessor.
