We can see two sections of a cervix. The top one is the best, so we’ll go with that. | We can see two sections of a cervix. The top one is the best, so we’ll go with that. On the bottom left corner can we see a very PAS-positive area. Upon closer inspection can we see that the PAS positive cells are stratified squamous cells. The other epithelium found in this section isn’t PAS-positive. This epithelial layer is also much thicker than the other. | ||
The PAS-negative epithelium contains pleomorphic cells (they have different shapes and sizes). These cells are larger than the PAS-positive cells as well. We can also see some cells undergoing mitosis here. A special cell type with a white “ring” around an irregular nucleus can be seen. | |||
