If cells are affected by HPV, what are they called and what is a defining characteristic?
Koilocytes
- hollow around the nucleus
What chemical is added to the cervical tissue to highlight the potentially cancerous tissue?
Acetic acid 5%.
stains proteins white - so higher protein producing cells will stain white.

Metastatic theory:
- due to retrograde menstruation or surgical procedures the tissue outwith undergo metastatic changes
Metaplastic theory:
- endometrium derives directly off the peritonium which may originate back.
