Gross findings of the post-operative pathological specimen showed an ischemic and partially necrotic uterus (Figure 1), while microscopic examination of the uterus revealed a severe acute inflammatory process with necrotic myometrium and bacterial colonies (Figures 2A,B), confirmed later to be Streptococcus pyogenes on blood-agar medium culture.
Histological specimens of the uterus. Microscopic examination of the uterus showing: (A) Hypertrophic post-partum uterus with acute inflammatory process characterized by extensive areas of recent hemorrhage and dilated congested vessels of the placental site. Black arrows indicate the focus of necrotic myometrium with bacterial colonies (hematoxylin and eosin staining, X1.25); (B) Acute inflammation with necrotic myometrium. Black arrows indicate bacterial colonies (hematoxylin and eosin staining, X60).
