Fibroblasts

Collagen is a protein formed by dermal cells that then produce ground substance, a protein lubricant that surrounds the dermal cells and fibers and contribute to the skins normal suppleness and turgor. The major component of elastic fiber (gives skin elasticity) is elastin.

obtained from intact primary lesions (bullae, vesicles, or pustules), if possible.

Cultures for bacterial infection

Always wear gloves. Using a tongue blade, gently scrape cells from skin lesions into a clean container and send to lab.

Cultures for fungal infection

A cotton-tipped applicator is used to obtain vesicle fluid from intact lesion. These are placed on ice immediately after collected and then transported to lab.

Cultures for viral infection (Herpes)

Apply an antibiotic ointment and place a sterile dressing on the incision.

Functions of the Skin

Papules

Primary Lesions; small, firm, elevated lesions less than 1 cm (elevated moles, warts)

Plaques

Primary lesions: elevated, plateau-like patches more than 1 cm that do not extend into the lower skin layers

Vesicles

Primary lesions; blisters filled with clear fluid, less than 1 cm in diameter

Wheals

Primary lesions; elevated, irregularly shaped, transient areas of dermal edema (insect bites)

Nodules

Primary lesions; elevated, marble-like lesions more than 1 cm wide and deep

Macules

Primary lesions; flat lesions of less than 1 cm; moles/freckles; most often brown, white or red

Patches

Primary lesions; macules larger than 1cm in diameter

Pustules

Primary lesions; vesicles filled with cloudy or purulent fluid (acne and acute impetigo)

Erosions

Primary lesions; wider than fissures but involve only the epidermis; often associated with vessicles, bullae, or pustules

Shave biopsy

Removal of only the portion of the skin elevated above the surrounding tissue. A scalpel or razor blade is moved parallel to the skin surface to remove the tissue specimen. Shave biopsies are usually indicated for superficial or raised lesions.

annular

Ringlike with raised borders around flat, clear centers of normal skin

Crusts and oozing

Secondary lesions; are composed of dried serum or pus on the skin beneath which liquid debris may accumulate; crusts frequently result from broken vessicles, bullae, or pustules

Lichentification

Secondary lesions; are thickened areas of epidermis with accentuated skin markings. They are caused by chronic rubbing and scratching

Atrophy

Secondary lesions; characterized by thinning of the skin surface with loss of skin markings; skin is translucent and paper like (striae or "stretch marks")

Ulcers

Secondary lesions; deep erosions that extend beneath the epidermis and involve the dermis and sometimes the subcutaneous fat

Fissures

Secondary lesions; linear cracks in the epidermis, which often extend into the dermis (athlete's foot)

Scales

Secondary lesions; visibly thickened stratum corneum; appear dry and usually whitish; most often seen with papules and plaques
