Chap. 4 Integument Pathology Flashcards
injuries to skin caused by excessive heat
burns
what kills people in burn injuries?
the escaping of fluid not the burn
how are burns categorized and what does it depend on?
depends on how long, exposure, how far or close the heat was; burns are categorized from 1st to 3rd degree, 1st being the least, 3rd being the most
1st degree burn
burn that just affects the epidermis; symptoms include: hyperesthesia (heightened sensitivity); erythema; no blisters; ex: steam burn or oven burn
2nd degree burn
affects epidermis and dermis; symptoms include: hyperesthesia (heightened sensitivity); erythema; blisters; ex: sunburns
3rd degree burn
affects all layers of skin; epidermis, dermis and hypodermis; symptoms include: anesthesia (without sensation) and/or hyperesthesia (heightened sensitivity); ex: black charred tissue (dead)
acne
inflammatory disorder of the sebaceous glands that produces bumps; as the glands produce more oil and you don’t wash your face the pores get clogged and then infected
albinism
an inherited condition where here is no melanin production in skin
alopecia
hair loss due to ageing, illness, or iatrogenic
cicatrix
scar; no way to predict what they look like
cyanosis
the appearance of blue skin due to lack of circulation (oxygen) or vasoconstriction; pink to white to blue to black
eczema
(dermatitis) autoimmune, acute, or chronic skin lesions characterized by erythema, itchiness, and edema (swelling)
gangrene
necrotic tissue
keloid
cicatrix gone wild/wrong
impetigo
bacterial infection; highly contagious; usually in children; usually on the face
ecchymosis
bruise caused by ruptured capillaries beneath the skin
capillaries
tiny blood vessels
Debridement
removal of damaged tissues and foreign debris to promote healing
skin graft
transplantation of skin from one person to another
autograft
same person is the donor and recipient of skin graft
dermaton
knife used in skin graft
basal cell carcinoma
nice cancer; slow growing; seldom (means rarely); metastasizes (cancer travels to make new tumors)
kaposi’s sarcoma
cancer that looks purplish patches (erythematous) in the lining of the nose, mouth, throat, and other organs; usually in AID’s patients; weakens the immune system
malignant melanoma
mean cancer; aggressive spreading cancer of melanocytes
ABCDE Rule
Asymmetry (can you split it evenly in half?)
Border (is it smooth?)
Color (does it have multiple colors? is it very dark?)
Diameter (is it bigger/smaller than 1/4 inches?)
Evolution (is it changing over time?)
done during your yearly skin check; doctor takes photos every year and documents them
squamous cell carcinoma
middle of the road cancer of squamous cells in skin
something weird on the skin
Noncancerous lesions
cyst
a thick walled pouch or sac containing fluid and pus down deep
