Exfoliative cytology means scraping the surface of a possible skin cancer with a knife and then spreading a small layer of the scrape onto a glass slide so that the cells in the scrape can be stained and looked at under a microscope..
It is easy to perform and it can be repeated multiple times with better sensitivity and specificity.
This aids to differentiate pre malignancies and malignancies.
There is no use of sharp scalpels for smear collection which is a great advantage over biopsy..
Papanicolaou's stain (PAP stain) is widely used in all cervical smear and non-gynaecologic exfoliative smears.
This is a transparent stain and gives very good cellular differentiation and nuclear details.

INTRODUCTION Cytology is a discipline that involves the morphologic study of cells.
It is broadly divided into exfoliative cytology and aspiration cytology.
Exfoliative cytology involves examination of specimens that contain cells exfoliated from body cavities and surface.
