Medical Terminology And Conditions Flashcards
Abrasion
A portion of the epidermis that has been scraped away.
Athletes feet
A superficial infection of the skin if the foot
Blister
A collection of serous fluid within the epidermis or between the epidermis and dermis, due to short-term but severe friction.
Cold sore (fever blister)
A lesion, usually in the oral mucous membrane, caused by type 1 herpes simplex virus (HSV) transmitted by oral or respiratory routes. The virus remains dormant until triggered by factors such as ultraviolet light, hormonal changes, and emotional stress.
Contact dermatitis
Inflammation of the skin characterized by redness, itching, and swelling and caused by exposure of the skin to chemicals that bring about an allergic reaction, such as poison ivy toxin.
Corn
A painful thickening of the stratum corneum of the epidermis found principally over toe joints and between the toes, often caused by friction or pressure. Corns may be hard or soft, depending on their location. Hard corns are usually found over toe joints, and soft corns are usually found between the 4th and 5th toes.
Frostbite
Local destruction of skin and subcutaneous tissue on exposed surfaces as a result of extreme cold. In mild cases, the skin is blue and swollen and there is slight pain. In severe cases there is considerable swelling, some bleeding, no pain, and blistering. If untreated, gangrene may develop. Frost bite is treated by rapid rewarming.
Hemangioma
Localized tumour of the skin and subcutaneous layer that result from an abnormal increase in blood vessels. 1 type is a port wine stain, a flat pink, red or purple lesion present at birth, usually at the nape of the neck.
Hives
Skin condition marked by reddened elevated patches that are often itchy. Most commonly caused by infections, physical trauma, medications, emotional stress, food additives, and certain food allergies.
Impetigo
Superficial skin infection caused by staphylococcus bacteria; most common in children.
Intradermal (intracutaneous)
Within the skin
Keloid
An elevated, irregular darkened area of excess scar tissue caused by collagen formation during healing. It extends beyond the original injury and is tender and frequently painful. It occurs in the dermis and underlying subcutaneous tissue. Usually after trauma, surgery, a burn, or severe acne; more common in people of African descent.
Keratosis
Formation of a hardened growth of epidermal tissue, such as a solar keratosis, a premalignant lesion of the sun-exposed skin of the face and hands.
Laceration

Psoriasis
A common, chronic skin disorder in which keratinocytes divide and move more quickly than normal from the stratum basale to the stratum corneum and form flakey scales, most often on the knees, elbows and scalp.
Pruritus
Itching, one of the most common dermatological disorders. It may be caused by skin disorders (infections), systemic disorders (cancer, kidney failure), psychogenic factors (emotional stress), or allergic reactions.
Topical
Refers to a medication applied to the skin surface rather than ingested or injected.
Wart
Mass produced by controlled growth of epithelial skin cells, caused by a papillomavirus. Most warts are noncancerous.
Bunion
A deformity of the great toe that typically is caused by wearing tightly fitting shoes. The condition produces inflammation of bursae (fluid-filled sacs at the joint), bone spurs and calluses.
Chiropractic/chiropractor
