Histopathology
Tumors
Malignant
Rapid
Invasion
not encapsulated
Usually recurrence occurs
Wide range of differentiation
Usually fatal
metastasis is there
1- losing E- cadherin molecules , local
degradation of basement membrane
and interstitial tissues, cells extrude
pseudopodia 2-Angiogensis 3-vascular
invasion and spread 4-establishment
of a new colony
Normal nuclei, few
mitotic figures, normal
cells , uniform size and
shape of cells
Anaplastic
Cells lose their normal
polarity, cellular
pleomorphism , nuclei are
bizzare ,pleomorphic, and
hyperchromatic. Increased
N/C ratio, coarse clumped
chromatin, prominent large
nucleoli, numerous and
atypical mitotic figures. tumor
giant cells
Anaplastic histology
benign
slow growth
Expansion
Encapsulated
No recurrence if it
is completely
removed
Not fatal unless it is
in vital sites
No metastasis
Well differentiated
Hyperchromatic,
increased N/C ratio
,abnromal mitotic
figures ,
pleomorphism
How cancer deveops
A genetic damage in
proto oncogene
Normally,
Help regulate cell growth
Mutated
Oncogenes
Product that helps
to accelerate cell
growth or cell
division
Tumor suppressor gene
Normally :Act to inhibit
cellular growth and division
When it is mutated,
no inhibitory effect
Leading to increased
growth+proliferation
DNA repair genes
Activation of TP53 by phosphorylation
Transcription of cyclin dependent kinase
inhibitor A (p21)
No RB phosphorylation
G1-S block in cell cycle
Helps cell to repair DNA
Normally
Mutation
Loss of TP53 or
mutation of TP53
DNA damage goes unpaired
becomes fixed in dividing cells
malignant transformation
Apoptosis genes
inherited
Autosomal dominant
Autosomal recessive
acquired
