What Is A Secondary Skin Lesion?

What is a tertiary lesion?

Tertiary (ie, late) lesions are caused by obliterative small vessel endarteritis, which usually involves the vasa vasorum of the CNS.

Factors that determine the development and progression of tertiary disease are not known..

How do you describe a lesion?

Elevated lesions are either solid or fluid-filled. Solid lesions can be described as either a papule, plaque, nodule, or wheal. A raised solid lesion is a papule when it is less than 1 cm and a plaque when it is a confluence of papules greater than 1 cm. A nodule is a solid lesion with a deeper cutaneous involvement.

What type of lesion is an open sore that causes loss of tissue?

An ulcer is a sore on the skin or a mucous membrane, accompanied by the disintegration of tissue. Ulcers can result in complete loss of the epidermis and often portions of the dermis and even subcutaneous fat.

What are some examples of fluid filled skin lesion?

Examples include cysts, lipomas, and fibromas. Vesicles are small, clear, fluid-filled blisters < 10 mm in diameter. Vesicles are characteristic of herpes infections, acute allergic contact dermatitis, and some autoimmune blistering disorders (eg, dermatitis herpetiformis).

Is tumor primary or secondary?

In medical lingo, “primary” refers to the original site of the tumor (for example, the breast or the colon). “Secondary” refers to any additional sites where the cancer has spread (for example, the lungs or the bone).

Is erosion a primary lesion?

Primary lesions Epidermal collarette, scar, excoriation, erosion, ulcer, fissure, lichenification, hyperpigmentation, callus.

What are primary and secondary skin lesions?

Identifying Primary and Secondary Skin Lesions Primary skin lesions are present at the onset of a disease. In contrast, secondary skin lesions result from changes over time caused by disease progression, manipulation (scratching, picking, rubbing), or treatment.

What are the characteristics of secondary skin lesions?

* Scale-heaped-up keratinized cells; flakey exfoliation; irregular; thick or thin; dry or oily; variable size; can be white or tan.

What is the difference between primary and secondary lesions?

Definitions of Primary and Secondary Lesions Primary skin lesions are those which develop as a direct result of the disease process. Secondary lesions are those which evolve from primary lesions or develop as a consequence of the patient’s activities.

What is a plaque skin lesion?

Plaque — a circumscribed, palpable lesion more than 1 cm in diameter; most plaques are elevated. Plaques may result from a coalescence of papules. Most plaques are elevated, but a plaque can also be a thickened area without being visibly raised above the skin surface.

What are examples of primary lesions?

Primary LesionsVesicle: a fluid-filled blister which is less than 5mm in diameter, elevated above the level of the skin with well demarcated borders.Bulla: a large vesicle (greater than 5 mm in diameter)Pustule: a pustule is similar in appearance to a vesicle or bulla, but contains purulent material.More items…•

What is an example of a secondary lesion?

Examples of secondary skin lesions are scales, crusts, excoriations, erosions, ulcers, fissures, scars, and keloids. Scales, which are shed dead keratinized cells, occur with psoriasis and eczema.

What are primary skin lesions?

Primary skin lesions are abnormal skin conditions present at birth or acquired over a person’s lifetime. Secondary skin lesions are the result of irritated or manipulated primary skin lesions. For example, if someone scratches a mole until it bleeds, the resulting lesion, a crust, is now a secondary skin lesion.

Is a Wheal a secondary lesion?

“Wheal” and “urticaria” are often use syn- onymously, although the former is the name of an eruption and the latter is a condition presenting these eruptions. A secondary lesion is an eruption that occurs secondarily after a primary or other skin lesion.

What is the difference between a papule and a nodule?

PAPULE – A circumscribed, elevated, solid lesion that is less than 10 mm* in diameter. PLAQUE – A circumscribed, elevated, solid lesion that is greater than 10 mm* in diameter and is usually broader than it is thick. NODULE – A palpable, solid lesion that is greater than 10 mm* in diameter.

What is a Wheal lesion?

Wheal: A wheal is an evanescent rounded or flat-topped elevation in the skin that is edematous, and often erythematous. They may vary in size from a few mm. to many cm. The shape may change and these lesions are usually pruritic (itchy). These are really variations of papules, nodules or plaques that are evanescent.

What does a lesion look like?

Skin lesions are areas of skin that look different from the surrounding area. They are often bumps or patches, and many issues can cause them. The American Society for Dermatologic Surgery describe a skin lesion as an abnormal lump, bump, ulcer, sore, or colored area of the skin.
