SKIN DISORDERS

ATHLETE'S FOOT

• Athlete's foot is a fungal infection that usually begins between the toes.
• Creates a scaly rash that usually causes itching, stinging and burning.
• Athlete's foot is contagious and can be spread via floors, towels or clothing.

BOILS AND CARBUNCLES

• A carbuncle is a cluster of boils — painful, pus-filled bumps.
• Carbuncles form under the skin.
• Boils usually start as red, tender lumps.

COLD SORES

• Cold sores are tiny fever blisters on the skin.
• They are fluid-filled lesions that occur on and around your lips.
• They usually go away within 2 weeks.

DERMATITIS

• Dermatitis is the inflamation of the skin.
• This disorder usually involves an itchy rash on swollen, reddened skin.
• Skin affected by dermatitis may blister, ooze, crust, or flake off.

IMEPTIGO

• Impetigo is a contagious skin infection that mainly affects infants and children.
• It usually appears as red sores on the face, especially the nose and mouth.
• The sores burst and develop honey-colored crusts.
• It can clear up in 2 to 3 weeks.

PSORIASIS

• Psoriasis is a common skin condition that changes the life cycle of skin cells.
• Psoriasis causes cells to build up rapidly on the surface of the skin.
• The extra cells form thick scales and itchy, dry, red patches that are painful.
• Psoriasis is a persistent, long-lasting disease.

1ST DEGREE BURNS

• The least serious burn of all 3.
• Only the outer layer of skin is burned.
• The skin will become red and often swell.

2ND DEGREE BURNS

• More serious than 1st degree burns.
• The skin will appear wet or moist.
• Affects first and second layers of skin.
• Blisters may develop and pain can be severe.

3RD DEGREE BURNS

• Most serious burn of all 3.
• Extends to the fat layer that lies under the skin.
• The skin may appear stiff, waxy white, leathery or tan.
• These types of burns usually require skin grafts for wound closure.

BASAL CELL CARCINOMA

• Basal cell carcinoma is a slow-growing form of skin cancer.
• Basal cell carcinoma is a type of nonmelanoma skin cancer.
• It effects even the deepest layers of the epidermis.

BASAL CELL CARCINOMA

• Often look like open sores, red patches, pink growths, shiny bumps, or scars.
• Usually caused by a combination of cumulative UV exposure.
• Almost never spreads beyond the original tumor site.
• In very rare cases it can spread and become life threatening.

SQUAMOUS CELL CARCINOMA

• Second most common form of skin cancer.
• Is an uncontrolled growth of abnormal cells arising in the squamous cells.
• Occurs on the outer layers of the skin where squamos cell are found.

SQUAMOUS CELL CARCINOMA

• Looks like red patches, open sores, elevated growthd or warts.
• They can crust and bleed, causing much pain.
• Is mainly caused by cumulative UV exposure over the course of a lifetime.
• It can become disfiguring and sometimes deadly if allowed to grow.

MALIGNANT MELANOMA

• Most dangerous form of skin cancer.
• Develop when unrepaired DNA damage to skin cells.
• Triggers mutations that lead the skin cells to multiply rapidly and form tumors.
• Tumors originate in the pigment-producing melanocytes in the basal layer.

MALIGNANT MELANOMA

• Melanoma often resembles moles on the epidermis.
• The majority of melanomas are black or brown.
• Melanoma is caused mainly by intense, occasional UV exposure.
• Melanoma kills an estimated 9,710 people in the US annually.

MELANOMA ABCD RULES

• A - Asymmetry
• If you draw a line through this, the two halves will not match.
• B - Border
• The borders of an early melanoma tend to be uneven.
• The edges may be scalloped or notched.

MELANOMA ABCD RULES

• C - Color
• A number of different shades of brown, tan or black could appear.
• Melanoma may also become red, blue or some other color.
• D - Diameter
• Melanomas usually are larger in diameter than the eraser on your pencil.
