Question 5

How would the nuclei appear in a malignant lesion?

Answer 5

Polymorphic and enlarged

Question 6

What makes neoplasia different from dysplasia?

Answer 6

Dysplasia will have increased cell abnormalities and is graded on severity

(Neoplasia - increase in cell numbers NOT due to stimuli)

Question 7

Answer 7

Decrease in cell size/no. of cells due to LOSS of stimuli

e.g. neural damage result in atrophy

Autonomous growth which has:
Invaded beyond normal location AND
has metastatic potential
