One place I was working at in Kansas, a large facility with over 30 suites, we were doing a D&C.
The patient was complaining of abdominal pain as well as a pussie discharge(yuck). Once the case started and her she was put in lithotomy, the smell started to permeate the room(rotting flesh and milk that has been left out in the hot sun for a week). What was pulled from her was a large clump of yellowish-grey tissue. By this time the whole half of the OR could smell it(winter green did not help at all).
We sent the specimen to pathology and awaited the verdict...it came back as unidentifiable. After the case we shut down the entire back wing of the OR for the rest of the night.
