OK, here it is:
When I was a 3rd-year med student doing a gyn oncology rotation in Miami I saw this heavy black woman (I think she was Creole) who had obviously been living in the back-woods (Okefenokee swamplands I guess). She came in with half her bottom eroded away by what we could only guess was a vulvar cancer.
No shit, it looked like a great white shark had taken a clean chomp out of the left side of her vulva, vagina, and butt. You could see the rectum (open like 4 inches up) and the cervix (also normally like 4-5 inches inside). Also all the rotting muscles of the glutes and even part of the femoris. You can imagine without a rectal sphincter, stool just flowed freely. As for the smell...even my vocabulary and ability to narrate could not do it justice.
The big question was how the f*ck this lady didn't "notice" this; it must have taken years to erode as it had. Truly a one-of-a-kind experience...
