Skin Flashcards
What is the Largest organ of the human body
skin
What does the skin regulate?
body temperature and provides protection
Dermis= ________ tissue
connective
Epidermis= __________ tissue
epithelial
The skin layer: Squamous cells is a
thin, flat cells on the top layer of the epidermis
The skin layer: of basal cells are
round cells beneath the squamous cells
Melanocytes are cells that produce the skin’s
pigment
» Skin cancers can occur anywhere, but are more common in areas that have been
exposed to the sun (face, neck, hands, etc.)
The skin cancer: Basal cell carcinoma (BCC) is a non-melanoma in the
stem cells of the deepest layer of the skin (stratum basale)
______ is the most common type of skin cancer
Basal cell carcinoma (BCC)
The skin cancer: Squamous cell carcinoma is a non-melanoma in the
superficial layers of the epidermis
The most aggressive type of skin cancer is
melanoma
Most melanomas occur from a change in a nevus that
already existed
Melanomas Arise from melanocytes in the
basal layer of the epidermis
____rule can help detect melanomas:
ABCD
What are the ABCD’s of melanoma
A- asymmetric
B- border irregularities
What are the ABCD’s of melanoma
C- color variation
What are the ABCD’s of melanoma
D- diameter >0.6cm and Dark color
What are the ABCD’s of melanoma
Common locations for melanomas are on the
face and scalp
what staging is used for non melanomas cancers ?
TNM staging
what staging is used for melanomas cancers?
clark method- categorizes lesion according to invasion through the levels of the epidermis and dermis
Breslow method - categorizes lesion according to vertical thickenss between the granular layer of the epidermis and deepest part of invasion
radiation for skin cancer is radiosensitive for ?
non nonmelanomas
radiation for skin cancer is radio resistant for ?
melanomas
The biopsy that uses a shave razor to shave off cells from the growth
Shave biopsy
uses a specific tool called a punch, or a trephine, which removes a circle of tissues from the growth
punch biopsy
use a scalpel to remove some of the growth
incisional biopsies
use a scalpel to remove the whole growth
excision biopsies
majority of non - melanomas skin cancers are
basal cell carcinoma
- most common location the nose
risks factors for non- melanomas include
UV exposure
fair/lights skin and eye color
history of sunburns
past radiation treatments
risk factor for melanomas include
fair complexion/white
UV exposure
exposure to toxins
sunburns
genetics / family history
clinical presentation for non - melanomas include:
change of the skin
- non-healing scar
-raised smooth shiny and pearly skin
- firm skin like a scar
white yellow or waxy coloring
raised
red or brown
scaly bleeding or crusty
