7
Abnormal mass of tissue
neoplasm
8
Growth exceeds and uncoordinated with that of the normal tissues
neoplasm
9
Persists in the same excessive manner after cessation of stimuli which evoked the change
neoplasm
10
Results from heritable genetic alterations that are passed down to the progeny of the tumor cells
neoplasm
11
Autonomous and progressive growth
neoplasm
12
Entire population of cells within a tumor arises from a single cell that has incurred a genetic change (clonal)
neoplasm
13
2 basic components of tumors (benign or malignant)
parenchyma
stroma/non-neoplastic stroma
14
basic components of tumors
made up of transformed or neoplastic cells
Parenchyma
15
basic components of tumors:
determines the biologic behavior of the neoplasm
Parenchyma
16
it is the component from which the tumor derives its name.
Parenchyma
17
basic components of tumors:
made up of connective tissue and blood vessels
Stroma / Non-neoplastic stroma
18
basic components of tumors:
carries the blood supply and provides support for the growth of parenchymal cells and is therefore crucial to the growth of the neoplasm.
Stroma / Non-neoplastic stroma
19
benign hollow cystic masses; typically they are seen in the ovary.
Cystadenomas
20
are benign epithelial neoplasms, growing on any surface, that produce microscopic or macroscopic finger-like fronds.
Papillomas
21
mass that projects above a mucosal surface, as in the gut, to form a macroscopically visible structure.
Polyp
22
Although polyps is commonly used for benign tumors, some malignant tumors may also appear as polyps. T OR F
TRUE
23
– this term is applied to benign epithelial neoplasms producing gland patterns and to those derived from glands but not necessarily exhibiting gland patterns.
Adenoma
24
A benign epithelial neoplasm arising from renal tubule cells and growing in glandlike patterns would be termed an , as would a mass of
adenoma
25
benign epithelial cells that produces no glandular patterns but has its origin in the adrenal cortex would be termed as
adenoma
26
– malignant neoplasms arising in mesenchymal tissue or its derivatives
Sarcomas
27
malignant neoplasms of epithelial cell origin with the consideration that the epithelia of the body are derived from all three germ layers
Carcinomas
28
all malignant neoplasm arising from the epithelia derived from all three germ layers are considered ---
carcinomas
29
* The mesoderm may give rise to carcinomas (epithelial) only. TRUE OR FALSE
FALSE. May be both
The mesoderm may give rise to carcinomas (epithelial) and sarcomas (mesenchymal)
