New cards
Stork bites
________ are NOT hemangiomas, they are harmless nevus simplex, dilated capillaries, and typically fade with time.
2
New cards
Mortality
________: how many people die from it.
3
New cards
Hamartomas
________: are "tumors "but NOT neoplasms, they are a disorganized overgrowth of different cells and tissues not normally found in an organ.
4
New cards
onkos
Oncology: the study of neoplasms, comes from the "________ "(a bulging mass)
5
New cards
Biological Behavior
________ of benign neoplasms: slow growth, often encapsulated, no metastasis, non- destructive.
6
New cards
proliferating "tumor" cells and supporting stroma with connective tissue and vessels.
Tumors have 2 basic components
7
New cards
Papillomas
________ arise from surface epithelium (skin, mouth, gut, bladder), usually are "finger- like "projections, and have various causes (HPV (CONTAGIOUS), warts, viral infections)
8
New cards
Neoplasms
________ are neoplastic growth with the uncontrolled or disorderly proliferation of cells resulting in benign or malignant tumors.
9
New cards
undifferentiated, uncontrolled growth, invasion of tissues around them, metastasis.
Malignant tumor
10
New cards
Hemangiomas
________: begin tumors of the vascular epithelium (color tells depth)
11
New cards
Resembles original tissue, grows slowly, does NOT metastasize, often encapsulated, does NOT invade and destroy.
Benign Neoplasms
12
New cards
Cherry Angiomas
________: AKA senile angiomas, occur with age.
13
New cards
Infantile Hemangiomas
________: most frequent- (4- 5 % of newborns), appear at 4- 6 weeks, grow quickly, and then disappear.
14
New cards
Hamartomas
________ are NOT a neoplastic proliferation of 1 cell type.
15
New cards
Neoplasia
"new growth"
16
New cards
Oncology
the study of neoplasms, comes from the "onkos" (a bulging mass)
17
New cards
Benign Neoplasms
Resembles original tissue, grows slowly, does NOT metastasize, often encapsulated, does NOT invade and destroy
18
New cards
Malignant Neoplasms
undifferentiated, uncontrolled growth, invasion of tissues around them, metastasis
19
New cards
Incidence
how many people get it
20
New cards
Mortality
how many people die from it
21
New cards
Biological Behavior of benign neoplasms
slow growth, often encapsulated, no metastasis, non-destructive
22
New cards
Nevus
the most common benign tumor, a pigmented mole, the proliferation of melanocytes
23
New cards
Hemangiomas
begin tumors of the vascular epithelium (color tells depth)
24
New cards
Infantile Hemangiomas
most frequent (-4-5% of newborns), appear at 4-6 weeks, grow quickly, and then disappear
25
New cards
Congenital Hemangiomas
less frequent, present at birth, may remain or shrink or go pale
26
New cards
Cavernous Hemangiomas
are most often congenital
27
New cards
Cherry Angiomas
AKA senile angiomas, occur with age
28
New cards
Hamartomas
are "tumors" but NOT neoplasms, they are a disorganized overgrowth of different cells and tissues not normally found in an organ
29
New cards
Adenomas
arise from glandular epithelium (colonic polyps, thyroid, liver)
