Abrasion
Scraping away of the skin my mechanical process or injury
Abscess
Localized collection of pus
Acne
Inflammatory disease of the skin involving the sebaceous glands and hair follicles
Actinic keratosis
Precancerous skin condition of horny tissue formation that results from excessive exposure to sunlight
Albinism
Congenital hereditary condition characterized by partial or total lack of pigmentation in the skin, hair, and eyes
Basal cell carcinoma
Epithelial tumor arising from the epidermis. It seldom metastasizes but invades local tissue, common in individuals who have had excessive sun exposure
Candidiasis
Infection of the skin, mouth (thrush) or vagina caused by yeast type fungus
Carbuncle
Skin infection composed of clusters of boils caused by staphylococcal bacteria
Cellulitis
Inflammation of the skin and subcutaneous tissue caused by infection, characterized by redness, swelling, and fever
Contusion
Injury with no break in the skin, characterized by pain, swelling, and discoloration (bruise)
Eczema
Non infectious, inflammatory skin disease characterized by redness, blisters, scabs and itching
Fissure
Slit or crack like sore in the skin
Furuncle
Painful skin node caused by staphylococcal bacteria in a hair follicle (boil)
Gangrene

Laceration
Torn, ragged edged wound
Lesion
Any visible change in tissue resulting from injury or disease. It includes sores, wounds, ulcers, and tumors.
MRSA infection

It can produce skin and soft tissue infections and sometimes bloodstream infections and pneumonia, which can be fatal if not treated.
Pediculosis
Invasion into the skin and hair by lice

Scleroderma
Disease characterized by chronic hardening of the connective tissue of the skin and other body organs
malignant growth that develops from scalelike epithelial tissue. Significant potential for metastasis. Frequent cause is chronic exposure to sunlight.
Squamous cell carcinoma
Systemic lupus erythematatosus
Chronic inflammatory disease involving the skin, joints, kidneys, and nervous system. This autoimmune disease is characterized by periods of remission and exacerbations.
Tinea
Fungal infection of the skin. This fungi may infect keratin of the skin, hairs and nails. Tinea capitis (scalp), tinea corporis (body) and tinea pedis (foot) (athletes foot). Ringworm
Urticaria
Itchy skin eruption composed of wheals (an individual hive) of varying sizes and shapes. Sometimes associated with infections and with allergic reactions to food, medicine or other agents.
Vitiligo
