Lesions 1
This flat, nonpalpable spot is a change in skin color, such as a freckle or age spot.
Macule – Primary Lesion
This small blister or sac contains clear fluid within or just beneath the epidermis.
Vesicle – Primary lesion
These pink or flesh-colored rough lesions caused by sun damage are precancerous and should be checked by a dermatologist.
Actinic Keratosis
This inflammatory disorder of the sebaceous glands is also called acne simplex or acne vulgaris.
Acne
Minor breakouts with mostly open comedones, some closed comedones, and a few papules describe this acne grade.
Grade acne I
This small elevation contains no fluid, although it may later develop pus.
Papule – Primary lesion. EX: Acne and warts
This large blister contains watery fluid and requires medical referral.
Bulla – Primary lesion
This is the most common and least severe skin cancer and may appear as a light, pearly nodule.
Basal cell carcinoma
This noninflamed buildup of cells, sebum, and debris inside a follicle may be open or closed.
Comedone
Many closed comedones, more open comedones, and occasional papules and pustules describe this grade
Grade acne II
This raised, inflamed lesion has a white or yellow center containing pus.
Pustule – Primary lesion
This itchy, swollen lesion may result from a bite, scratch, allergy, or nettle sting.
Wheal – EX: Hives and mosquito bites
This cancer is more serious than basal cell carcinoma and may appear as scaly red or pink papules, nodules, open sores, or crusty areas.
Squamous cell carcinoma
This clogged follicle is open to air; its dark color results from oxidation, not dirt.
Open comedone/blackhead
Red, inflamed skin with many comedones, papules, and pustules describes this grade.
Grade acne III
This secondary lesion is a crack that penetrates into the dermis.
Fissure. EX: Severely chapped hands, lips or feet.
This secondary lesion is a thick scar caused by excessive growth of fibrous tissue.
This is the most serious skin cancer because it can quickly metastasize.
Malignant melanoma
These firm, pearl-like white papules have no visible opening and are often mistaken for whiteheads.
Milia – Small epidermal cysts of sebum and dead cells
Cysts plus comedones, papules, pustules, inflammation, and common scarring describe this grade.
Grade acne 4
This open lesion involves loss of skin depth and may weep fluid or pus; it requires medical referral.
Ulcer – Secondary lesion
These vascular lesions involve the blood or circulatory system and are classified as this level of lesion.
Tertiary lesions – EX: Rosacea and Telangiectasia
In the ABCDE checklist, these two letters stand for irregular edges and a changing lesion.
B for Border and E for Evolving
This hereditary tendency causes acne-prone skin to retain dead cells inside follicles, worsening papules and pustules.
Retention hyperkeratosis
Name four broad acne triggers listed in the lesson
genetic, hormonal, environmental, lifestyle, product, or dietary influences
