Write all the parts you
see on here
EXTRA CREDIT!
On a SEPARATE sheet of paper, you and a
partner decide what disease or disorder is
being descried and write it down.
The top 3 groups with the most correct will
get ec slips
DERMATOLOGY
The study of the skin and its parts
ATHLETE’S FOOT
An itchy, red, peeling condition of the skin
between the toes.
Cause: fungus infection (usually from public
bathrooms and showers)
BOILS
Infected hair follicles; large and pus-filled.
CAUSE: bacteria
SHINGLES
Viral infection of the nerve endings in the
skin. Severe itching and painful
COLD SORES
Small fluid-filled blisters that itch and sting
CAUSE: herpes simplex virus
Usually occur around mouth and lips
Virus dormant in nerve – stimulated by stress, fever,
or sunlight
CONTACT DERMATITIS
Itching, redness, swelling of skin, may blister.
CAUSE: chemicals or plants (poison ivy)
IMPETIGO
Pink, water-filled, raised lesions that develop
a crust and rupture. Usually around the
mouth and nose
CAUSE: staph infection (highly contagious)
Common in young children
PSORIASIS
Dry, silvery scales on the skin. Skin can flake
off in large amounts. (Noncontiguous)
In normal growth pattern, the skin cells are created in
the basal layer and then move
up to the outer layer of the skin. The dead cells are shed from
the skin at the same rate as new cells are produced maintainin
g a balance. The normal course of this phenomenon is about 28
days from cell birth to death.
In psoriasis, the affected areas switch
from normal growth pattern. More
cells are created and pushed to the su
rface very fast. The skin cannot
shed as fast as growth occurs.
The excessive skin cells builds
up and form elevated
scaly lesions. The white scales that us
ually cover the lesion is a
component of dead skin cells.
The redness is caused by the increase
d blood supply to the affected area.
RINGWORM
Scale, reddish, ring-shaped patches on the
skin
CAUSE: fungus
ECZEMA
Red, scaly, itching patches of skin. Common
in young children. (noncontagious)
BED SORES
Sores causes by decrease in blood supply and
constant pressure on the skin (decubitus
ulcer)
ACNE
Inflammation of the sebaceous glands.
CAUSE: bacteria, oil, dead cells
blocking pores
WARTS
bumps on the
surface of the skin
that are rough and
hard.
CAUSE: viral
infection of the
epidermis
BLACKHEADS AND
WHITEHEADS
Keratin plugs the hair follicles and blocks
sebum. Turn black when exposed to air.
FOLLICULITUS
Infection of the scalp, pus umps and redness
around the hair.
CAUSE: bacteria (common with use of hair
pomades)
RAZOR BUMPS
Bumps usually seen around the male faces.
Due to curly hairs coming out, then growing
back into the skin.
EPIDERMOLYSIS BULLOSA
Heredity disorder
Layers of the skin can easily be pulled apart.
A simple touch can separate the layers and
cause blisters or rip.
HERPES SIMPLEX
Cold sore – viral infection of the skin that may
reoccur. This is because the virus hides in nerves.
• Group of small red bumps that blister, itch or burn.
Dry up in a few days and form yellow crust. Lasts
10-14 days.
• Causes: skin contact (kissing, sharing drinks,
towels, etc.) fever, stress
ROSACEA
Common face rash of adults. Redness of face,
some swelling, pimples. May last for years.
CAUSE: unknown, may be sunlight
XEROSIS
Dry skin – can see it because the dead squamous
cells are flaking off in excess amounts
CAUSE:
• long hot baths, showers – remove body oils
• Some soaps
• Cold air
TREATMENT:
• Blot skin after showers, then apply moisterizer
• Alpha hydroxyacid lotions best
• Best soaps: Dove, Oil of Olay, Cetaphil
PRURITUS
Itching of skin
MANY STORIES THAT STARTED IN THE
MIDDLE AGES COME FROM THE FACT
THAT DISEASES WERE NOT
UNDERSTOOD…for example vampires
and werewolves.
PORPHYRIA
When skin exposed to sunlight lesions and scars
develop, gums degenerate. Due to lack of iron
part of hemoglobin. These people avoided the
light (middle ages – vampires). To help, can inject
heme from healthy patients (before could do this,
drink heme from blood)
Garlic – severely aggravates the porphyria symptoms
ALSO some have excess hair growth on the face and
hands – wolflike look
