Lesion

any mark, symptom, or abnormality -structural change in tissue -caused by damage or injury -very general term

3 types:primary, secondary, tertiary

primary

l

Lesions

BullaCyst

MaculePapulePustule

TubercleTumor

VesiclesWheal

*9 types

Primary: Bulladef: large blister w/ fluid

Bulla=Big Blister

Primary: Vesicledef: small blister w/ fluid

poison ivy

vesicle is a small enclosure

vesicle=small blister

Primary: CyStclosed, abnormally developed sac

above or below skin

Primary: Maculediscoloration

flat

Macule has freckles

any discoloration that is flat=macule

Primary: Papulepimple

no fluidmay develop pus

Papule

Primary: Pustuleinflamed pimple

=inflamed papule

WITHpus (white/yellow center)

*fluid contains bacteria, debris from infection

PUSTULE

about to BUST

Primary: tuberclerounded, solid lump

abnormallarger than papule

Primary: tumorabnormal cell mass

because cells abnormally multiply

tumors

Primary: wheal(aka welt)

itchy, swollencause: allergy, insect bite

secondary

l

Lesionsdevelop in later stages of disease

CrustExcoriation

FissureKeloidScaleScarUlcer

*7 types

secondarY: CRUSTdead cells

over wound/blemish while healing

ex: scab

CRUST(scab)

secondarY: Excoriationsore/abrasionby scratching/scraping

ex: acne excoriee (client scrapes off acne)

excoriation

acne excoriee

secondarY: Fissurecrack in skin

goes deeper than outside layer of skin (dermis)

ex: chapped lips, hands

Fissurechapped or very dry

Fissure=crack

secondarY: keloidthick scar

excessive growth of callagen after injury

Keloids

secondarY: scaleflaky skin cells

on dermisdry or oily

ex: dandruff

scales

secondarY: scarforms after lesion/injury heals

light coloredtissue hardens

secondarY: ulceropen lesionloss of skin depth,

from infection or cancer

mouth, stomach, etc.

sebaceous glandsDisorders

AcneAsteatosisComedoneFuruncle

MiliaRosacea

Sebaceous hyperplasiasSeborrheaStreatoma

oil(sebaceous)Gland: ACNEchronic

inflammation of oil glands

characterized by blemishes/comedones(blackheads)from infection or cancer


oil(sebaceous)Gland: Asteatosisdry, scaly skin

lack of sebum(oily substance)

causes: harsh soaps, cold exposure, aging, etc.



oil(sebaceous)Gland: comedoneblackhead

skin cells & hardened oil clogging pore

dark b/c exposed to oxygenfrom infection or cancer


oil(sebaceous)Gland: furuncleboil

caused by bacteria from hair follicles

mouth, stomach, etc.ca

they really hurt!

whiteheadsoil & dead cells under skin

more common with dry skinfrom infection or cancer

oil(sebaceous)Gland: rosaceachronic redness

on cheeks and noseaggravated by heat, alcohol, stress, sun, caffeine


rosacea

oil(sebaceous)Gland: sebaceous h Hyperplasias

overgrowth of sebaceous glandbenign lesions

oily areasonly surgically removed



Hyper=?Very/over (ex: hyperactive)

Plasia=?growth

Subaceous Hyperplasia=oil gland overgrowth!

oil(sebaceous)Gland: seborrheasevere oiliness

ending -”orrhea”=flow or discharge

therefore: seborrhea=oil overflow!!!

oil(sebaceous)Gland: steatomaoil cyst (sebaceous cyst)

size: pea to orange

appears on scalp, neck, backfrom infection or cancer


sudoriferous glandsexcrete SWEAT

sudoriferous glandsDisorders

AnhidrosisBromhidrosisHyperhidrosisMilaria rubra

sweat(sudoriferous)Gland: Anhidrosis

deficiency in perspirationbecause of fever or skin disease

required medical treatment



An=?not or without

Hidrosis=?sweating

Anhidrosis=without sweat

sweat Gland: bromhidrosis

bad smelling perspiration

armpits or feet

brom=odor

hidrosis=?

Bromhidrosis=foul-smelling sweat (odor sweat)

sweat(sudoriferous)Gland: hyperhidrosis

over-sweating

becuase of heat or body weakness

hyper=over/too much

hyperhidrosis=over sweating

sweat Gland: Milaria Rubra

inflammation of sweat glands=heat(sweat) rash!

itching, burning skin from excessive heat exposure

red vesicles(blisters) erupt

heat rash=miliaria rubra

inflammations of the skin

Atopic dermatitiscontact dermatitis

dermatitiseczema

what is dermatitis?skin inflammation

frecklesmay be because of sun exposure

macules



hyperpigmentation disorders: MELASMA

TERM FOR HYPERPIGMENTATION

pregnancy mask=tan b/c of hormone changes



hyperpigmentation disorders:

Nevus

birthmark or moleabnormal pigmentation



hyperpigmentation disorders: stain

Discolorationoccur after certain diseases or

after freckles, moles, etc disappear




hyperpigmentation disorders: Tan

caused by exposure to sunmelanin production

defense against UV rays




hypopigmentation

hypopigmentation disorders:

leukoderma

light, abnormal patchesdisease that destroys pigment-producing cells

ex: albinism, vitiligo



hypopigmentation disorders: albinismlack of melanin pigment

in skin, hair, eyesgenetic

very sensitive to light




hypopigmentation disorders: vitiligowhite spots/light colored areas of skin

b/c of lack of pigmentworsened by sunlight




Hypertrophies=abnormal growths

Keratomathickened skin (epidermis)

ex: callus

keratosesthick buildup of cells

keratosis pilarisbumpiness b/c of blocked follicles

exfoliation can help

Molebrownish spot

don’t remove hairs in moles

skin tagsmall over-growth

common on arms & neck

verrucawart

caused by virusinfectious, contagious

skin cancer----------------------------------------

skin cancer:cause: sun exposure

3 forms

scaly red growths

malignant melanomamost serious

black/dark patches, uneven texture

contagious diseases

conjunctivitispink eye-bacterial

herpes (simplex)virus

-never work on client if they have current lesions

impetigobaterial infection

small blisters/crusty lesionsvery contagious

tinea=fungal infection

tinea corporisringworm

very contagious

tinea versicoloryeast infection

verruca=wart

quick stats-80% of sun exposure you get before 18 yrs.

-1 person/hr dies of skin cancer in US

-skin cancer kills more women in late 20’s/early 30’s than breast cancer

-most parents do not correctly use sunscreen on children (93%)

-33% of adolescents never use sun screen

acne------------------

acne -primary concern of many clients

-triggered by hormonal changes

causes clogged pores

bacteria

cosmetic products

triggers(hormones, foods, stress)

4 classes of acne1-least severe4-most severe

yay chapter 9!suggestions:

go over slides a few more timesmake flash cards with difficult terms & definitions

read book to help with hard topicslook at pictures of skin disorders on internet to help
