Primary, Secondary, & Tertiary
Primary Lesion
Lesions in early stages of development or change.
Primary Lesions Characterized by:
Flat, nonpalpable changes in skin color or by elevations formed by fluid in a cavity, such as vesicles or pustules.
Bulla
Large blister containing watery fluid. Similar to vesicle, but larger
Cyst
Closed, abnormally developed sac containing fluid, infection, or other matter above or below the skin.
Macule
Flat spot or discoloration of the skin. Natural freckles, can also be red.
Nodules
Smaller than tumors, caused by conditions such as scar tissues, fatty deposits or infections.
Papule
Small elevations on the skin that contains no fluids, but may develop into a pustule. Less than a half an inch in diameter, and may have varied appearance in color and are either rounded, smooth or rough.
Pustule
Inflamed papule with a white or yellow center containing puss. Fluid consisting of white blood cells, bacteria and other debris. Small pus-contained blister that may or may not be caused by an infections. Acne pustules in hair follicles are not infectious.
Tubercle
Abnormal rounded, solid lump; larger than papule.
Tumor
Large nodule, abnormal cell mass resulting from excessive cell multiplication, varying in size, shape, and color.
Vesicle
Small blister or sac containing clear fluid. Poison ivy produces vesicles.
Wheal
Itchy swollen lesion caused by a blow, insect bite, skin allergy reaction or stings. Hives, and mosquito bites are wheals.
Urticaria
Hives, can also be caused by exposure to allergens used in products.
Secondary Lesions
Skin damage, developed in the later stages of disease, that changes the structure of tissues or organs. Later stages of disease and change the structure of tissues and organs.
Vascular Lesion
Involve the blood or circulatory system.
Tertiary Lesions
AKA Vascular lesions, involve the blood or circulatory system.
Crust
“Scabs” Dead cells formed over a wound or blemish while it is healing. Accumulated of sebum pus, and sometimes mixed with epidermal material.
Excoriation
Skin sore or abrasion produced by scratching or scraping.
Acne Excoriation
Disorder where clients purposely scrape off acne lesions, causing scarring, and discoloration.
Fissure
Crack in the skin that may penetrate into the dermis. Chapped lips, cracked heals, and hands, are examples.
Keloid
Thick scar resulting from excessive growth of fibrous tissue (collagen) Usually found in those that are genetically predisposed to them, and may occur following an injury or surgery (Usually Fitz VI)
Scale
Excessive shedding of dead skin cells; flaky skin cells; any thing plate of epidermal flakes, dry or oily. Example dandruff or psoriasis
Scar
Discolored, slightly raised mark on the skin formed after an injury or lesion of the skin has healed. Tissue hardens to heal the injury.
Hypertrophic
Thick elevated scars.
Ulcer
Open lesion on the skin or mucous membrane of the body accompanied by pus and loss of skin depth; deep erosion or depression in the skin. Normally due to infection or cancer. Requires medical referral.
Disorders of the Sebaceous (oil) glands include:
Acne, Asteatosis, Comedones, Furuncle, Carbuncles, Milia, Sebaceous Hyperplasia, Seborrhea, Seborriheic Dermatitis, Steatoma.
Acne
Chronic infammatory skin disorder of the sebaceeous glands. Characterized by comedones, and blemishes. Inflammation of sebaceous glands results from retained oil secretions, cells, and excessive Propionibacterium acne (P.acne) bac
Common Acne is known as:
Acne simplex, or Acne Vulgaris
Propionibacterium Acne
(P. acne) Bacteria
Asteatosis
Dry, scaly skin from sebum deficiency; can be due to aging, internal disorders, alkalies of harsh soaps or cold exposure.
Comedo (Comedones; plural)
Noninflamed buildup of cells, sebum, and other debris inside follicles.
Open Comedo
Blackhead open at the surface and exposed to air. The follicle is filled with an excess of oil a blackhead forms. Dark color is dues to oxidation occurring.
Closed Comedo
Openings of follicles are blocked with debris and white cells. AKA Whitehead.
Furuncle
A Boil, subcutaneous abscess filled with pus. Furuncles are caused by bacteria in glands or hair follicles.
Carbuncles
Groups of boils.
Milia
Epidermal cysts that are small, firm white papules. Whitish, pearl-like masses of sebum and dead cells under the skin. No visible opening, often mistakenly called whiteheads. (whiteheads are softer) Hardened and closed over. Common in dry skin types. Has to be lanced or opened to extract.
Sebaceous Hyperplasia
Benign lesions frequently seen in oilier areas of face. Often white, yellow or flesh colored. Described as doughnut-shaped with an indentation in the center. Sebaceous material may be found in the center. Harmless lesions that cannot be extracted. Has to be removed surgically.
Seborrhea
Severe oiliness of the skin.
Seborrheic Dermatitis
Inflammation, dry or oily scaling or crusting, and itchiness. Red flaky skin often appears in the eyebrows, scalp, hair line, the middles of the forehead and along sides of the nose. Sometimes treated with cortisone creams. Sever cases should be referred to a dermatologist. Commonly known as eczema.
Steatoma
Sebaceous cyst or subcutaneous tumor filled with sebum and ranging in size from a pea to an orange. Usually appears on the scalp, neck and back.
Wen
Steatoma
Disorders of Sudoriferous (Sweat) Glands
Anhidrosis, Bromhidrosis, Hyperhidrosis, and Miliaria Rubra.
Anhidrosis
Deficiency in perspiration, due to failure of sweat glands. Often results from a fever or skin disease. Requires medical attention.
Bromhidrosis
Foul-smelling perspiration. Caused by bacteria and yeast that break down sweat on the surface of the skin.
Hyperhidrosis
Excessive perspiration, caused by heat, genetics, medications or medical conditions.
Diaphoresis
Hyperhidrosis
Miliaria Rubra
Also known as “prickly heat” Acute inflammatory disorder of sweat glands. Results in eruption of red vesicles, burning, and itching skin from excessive heat exposure.
Inflammations of the skin
Dermatitis, Atopic Dermatitis, Contact Dermatitis, Perioral Dermatitis, Eczema, Edema, Erythema, Folliculitis, Pseudofolliculitis, Pruitis, Psoriasis, Urticaria.
Dermatitis
Inflammatory condition of skin; various forms include lesions such as eczema, vesicles, or papules.
3 Main categories of Dermatitis
Atopic, Contact, & Seborrheic
Atopic Dermatits
Chronic relapsing from of dermatitis. “excess inflammation due to allergies” Irritants and allergens that trigger reactions that include dry cracking skin.
Dehydration makes worse, use humidifiers and lotion to keep skin hydrated.

Allergies to red dyes in products, and nickel in jewelry are common.
Irritant contact dermatitis
Localized inflammatory reaction caused by exposure to caustic irritants.
Dermatitis Venenata
Occupations disorders from ingredients in cosmetics and chemical solutions.
Perioral Dermatitis
Acne-like condition around the mouth; consists of mainly small clusters of papules, not contagious. Antibiotics can help condition.
Eczema
Painful itching disease of the skin; acute or chronic in nature, with dry or moist lesions. Refer to physician. AKA Seborrheic dermatitis, also a sebaceous gland disorder.
Characteristics: Scaling around, nose, ears, scalp, eyebrows, and mid-chest areas. Flaking mainly affects oilier areas.
Edema
