DISORDERS OF THE SKIN
CHAPTER 21
A MARK ON SKIN
INDICATES INJURY OR DAMAGE THAT CHANGE THE STRUCTURE OF THE TISSUE OR ORGAN
3
TYPES OF LESIONS
PRIMARY, SECONDARY AND TERTIARY
COSMETOLOGIST NEED TO BE CONCERNED WITH PRIMARY AND SECONDARY LESIONS ONLY!!!!!!
DIFFERENT COLOR THAN SKIN
RAISED ABOVE THE SKIN SURFACE
REQUIRE MEDICAL REFERRAL!!!!!!
BULLA
BLISTER CONTAINING WATERY FLUID
REQUIRES MEDICAL REFERRAL
CYST
CLOSED, ABNORMALLY DEVELOPED SAC
CONTAINS FLUID PUS, SEMI-FLUID
ABOVE OR BELOW THE SKIN
MACULE
SMALL DISCOLORED SPOT OR PATCH ON THE SURFACE OF THE SKIN
FRECKLES
NEITHER RAISED OR SUNKEN
NODULE
SOLID BUMP LARGER THAN 1 CM
CAN EASILY BE FELT
REQUIRES MEDICAL REFERRAL
CARCINOMA
EXAMPLE BREAST CANCER
PAPULE
RAISED BUMP
RED OFTEN DUE TO SWELLING
THEY DO NOT HAVE A HEAD OF PUS
PUSTULE
RAISED
INFLAMMED PIMPLE CONTAINING PUS
TUMOR
ABNORMAL CELL MASS
RESULTS FROM EXCESSIVE
MULTIPLICATIONS OF CELLS
VARY IN SIZE, SHAPE AND COLOR
VESICLE
SMALL BLISTER FILLED WITH CLEAR FLUID
POISON IVY
LIES WITHIN OF JUST BENEATHE THE EPIDERMIS
WHEAL
ITCHY SWOLLEN LESION
LASTING ONLY A FEW HOURS
CAUSED BY A BLOW, THE BITE OF AN INSECT OR SKIN ALLERGY
EXAMPLE HIVES OR MOSQUITO BITE
SECONDARY LESION
CHARACTERIZED BY PILES OF MATERIAL RAISED ON THE SKIN SURFACE OR DEPRESSION IN THE SKIN SURFACE SUCH AS AN ULCER
DISORDERS OF THE SUDERFEROUS GLANDS
ANHIDROSIS
- LACK OF PERSPIRATION; OFTEN RESULT OF FEVER
CRUST
DEAD CELLS THAT FORM OVER A WOUND OR BLEMISH WHILE HEALING
AN ACCUMULATION OF SEBUM AND PUS
EXCORIATION
SKIN SORE OR ABRASION
PRODUCED BY SCRATCHING OR SCRAPING
FISSURE
CRACKS IN THE SKIN
PENETRATES INTO THE DERMIS
EX. CHAPPED LIPS
KELOID
THICK SCAR
EXCESSIVE GROWTH OF FIBROUS TISSUE
SCALE
THIN PLATE OF EPIDERMAL FLAKES
DRY OR OILY
EXCESSIVE DANDRUFF
SCAR OR CICATRIX
LIGHT COLORED
SLIGHT RAISED MARK ON SKIN
FORMED AFTER AN INJURY ON SKIN HAS HEALED
ULCER
OPEN LESION ON SKIN OR MEMBRANE OF BODY ACCOMPANIED BY PUS AND LOSS OF OF SKIN DEPTH
COMEDONES
ALSO CALLED A
BLACKHEAD
HAIR FOLLICLES FILLED WITH
KERATIN AND SEBUM
A CLOSED COMEDONE IS CALLED
A
WHITEHEAD
MILIA
BENIGN; KERATIN-FILLED
CYST THAT APPEARS JUST
UNDER THE EPIDERMIS WITH NO
VIBIBLE OPENINGS
RESEMBLE
SESAME SEEDS
ACNE
CHRONIC IMFLAMMATION OF THE
SEBACEOUS GLANDS FROM RETAINED
SECRETIONS AND BACTERIA
OCCURS FREQUENTLY ON THE FACE, CHEST,
OR BACK
ACNE OR COMMON PIMPLE IS KNOWN
AS ACNE SIMPLEX OR ACNE VULGARIS
ITS DOES NOT JUST HAPPEN
TO TEENAGERS; ADULTS CAN GET
ACNE
SEBACEOUS CYST
LARGE; POCKET LIKE LESION
FILLED WITH SEBUM
FREQUENTLY SEEN ON SCALP AND BACK
IT SHOULD BE REMOVED BY A PHYSIAN
SEBORRHEIC DERMATITIS
SKIN CONDITION CAUSED BY
AN INFLAMMATION OF THE
SEBACEOUS GLAND
ROSACEA
CHRONIC INFLAMMATORY CONGESTION OF
CHEEKS AND NOSE
ITEMS THAT AGGRAVATE ROSACEA ARE SPICY FOODS,
CAFFEINE, ALCOHOL, EXPOSURE TO EXTREME HEAT AND COLD OR SUNLIGHT AND STRESS
BROMIDROSIS
-FOUL SMELLING PERSPIRATION

HYPERHIDROSIS
-EXCESSIVE PERSPIRATION; CAUSED BY EXCESSIVE HEAT OR GENERAL BODY WEAKNESS

MILARIA RUBRA
-ACUTE INFLAMMATION DISORDER; CAUSED BY ERUPTION OF SMALL RED VESICLES AND ACCOMPANIED BY BURNING OF ITCHING
SKIN INFLAMMATIONS
Conjunctivitis
-known as pink eye; contagious

-inflammation of skin with lesions
Eczema
-skin inflammation of acute or chronic
nature; in forms of dry or moist lesions accompanied by itching and burning

pigment can be affected by internal factors; such as hereditary, or hormonal fluctuations or by outside factors such as prolonged sun exposure
HYPERPIGMENTATION OF THE SKIN
darker than normal pigmentation in splotches

light, abnormal patches in the skin, caused by a burn or congenital disease that destroys the pigment-producing cells
vitiligo or albinism are examples

SKIN CANCER
basal cell carcinoma
most common
least sever

squamous cell carcinoma
more serious than basal cell
characterized by scaly red papules or nodules
malignant melanoma
most serious form of skin cancer
characterized by black or dark brown patches on the skin
appear uneven in texture, jagged or raised
basal cell carcinoma
squamous cell carcinoma
malignant melanoma

A-ASYMMETRY

D-DIAMETER
E-EVOLVING
ACNE AND PROBLEMS OF SKIN
a disorder affected by heredity and hormones
retention hyperkeratosis-retains dead cells in follicle forming an obstruction that clogs the follicle and exacerbates inflammatory acne lesions

propionibacterium acnes-follicles are obstructed, oxygen is blocked from the bottom, allowing acne bacteria to multiply

main food source-fatty acids which are obtained from an abundance of sebum
