29
lesions are described by their
appearance, color, location, and size on centimeters
30
primary skin lesions
initial reaction to pathologically altered tissues- may be flat or elevated
31

39
ulcer
an open sore or lesion that extends to the dermis- usually heals with scarring
-pressure sore
-basal cell and carcinoma
39
excoriations
linear scratch marks or traumatized abrasions of the epidermis,
-scratches
-abrasions
-chemical or thermal burn
39
fissure
deeper; small slit or crack- like sore that extends into the dermal layer, could be cause by continuous inflammation and drying
40
burns
injures that are caused by contact with thermal, chemical, electrical or radioactive agents
41
systemic effects of burns
life threatening and may included dehydration, shock, and infection
42
burns are usually classified as...
first, second, or third-degree
42
first degree burns (superficial burn)
-epidermis is damaged
symptoms restricted to local effects (skin redness, acute sensitivity to sensory stimuli (touch, heat or cold)
does not blister
heals with scarring
sunburn or hot water
43
erythma
skin redness
43
second degree burn (partial thickness burn)
deep burn the damages both the epidermis and part of the dermis
44
hyperesthesia
acute sensitivity to sensory stimuli
- touch, heat, cold
45
what is second degree burns characterized by
fluid- filled blisters (vesicle or bullae) created by the deeper penetration of heat
46
recovery from second degree burns
is more painful and recovery is usually slow but complete with scare formation
- seriousness depends on how much of the dermis has been injured
47
third degree burns
-full thickness burn
both the epidermis and dermis are destroyed and some of the underlying connective tissue is damaged, leaving the skin waxy and charred with insensitivity to touch
48
what develops after a third degree burn
ulcerating wounds develop and the body attempts to heal itself by forming scar tissue `
49
dermatoplasty
skin grafts that are frequently used to assist recovery in third degree burns
49
rule of nine
emergency ,method for estimating the extent of burn damages
50
the rule of nine calculates
body surface involved in burns by assigning values of 9% or 18% of surface areas to specific regions
51
why is the rule of nine important
accurate estimation of damaged surface area to know treatment with I.V fluid
52
antiacne agents
reduce acne through multiple mechanisms
53
antifungals
use to threat fungal infection. Alter the cell wall of fungi or disrupt enzyme activity resulting in cell death
54

inhibit inflammation, redness, and itching caused by allergic skin reaction and the release of histamine
55
antiparasitics
kill insect parasites such as mites and lice
56
antiseptics
topically applied agents that limit growth of bacteria, thus preventing infection in cuts, scratches, and surgical incisions
57
corticosteroid
decrease inflammation and itching by suppressing the immune systems response to tissue damage
58
keratolytics
destroy and soften the outer layer of skin so that it is sloughed off or shed
59
protectives
cover, cool, dry or sooth inflamed skin
60
topical anesthetics
block sensation of pain by numbing the skin layers and mucous membranes
61
oncology
branch of medicine dealing with tumors`
62
neoplasms
abnormal growth of new tissues that can be benign or malignant
63
benign neoplasms
noncanercous growths composed of the same type of cells as the tissues in which they are growing
-place pressure on surrounding structure
64
malignant neoplasm
composed of cancerous cells that do not necessarily resemble the tissue in which they are growing
- cells show altered function, appearance
-uncontrolled growth
-invade the surrounding tissue
65
malignant neoplasms can break
loose from the primary tumor, enter blood and lymph vessels, and travel to remote regions of the body to FORM SECONDARY TUMOR SITES
66
metastasis
the ability to invade surrounding tissue and spread to remote regions of the body
67
four grades of severity
grading system used to evaluate the appearance and maturity of cancer cells in tumors based on the microscopic appearance of cancer cells
68
grade 1 tumor has the ______ prognosis; grade 4 has the ______ prognosis
best, weak
69
TNMI
systems of staging to determine how much cancer has spread within the body
70
TNMI stands for
T- refers to the size and extent of the primary tumor
N- indicates number of area lamp nodes involved
M- refers to any metastases of the primary tumor
A- subscript number is used to indicate the size or spread of the tumor
71
Basal cell carcinoma
most common type of skin cancer
-malignancy of the hair follicle (commonly caused by overexposure to sunlight )
72
basal cell carcinoma is more prevalent in
blond, fair skinned men and it is the most common malignant tumor affecting caucasians
73
basal cell carcinoma ulcerate
as they increase in size and develop crusting that is firm to the touch
74
basal cell carcinoma metastases are
uncommon; the invade the tissues sufficient to destroy an ear, nose, or eyelid
75
squamous cell carcinoma arises from
keratinizing epidermal cells
76
squamous cell carcinoma is most common in
fair skinned white men over 60
77
what greatly increases the risk of squamous cell carcinoma?

81
who is at the greatest of malignant melanoma
fair complexion, blue eyes, red/blonde hair, and freckles
82
what caused malignant melanoma
excessive exposure to sunlight and severe sunburn during childhood are believe to increase the risk of melanoma
