CULTURE AND GENETICS Genetic attributes of dark-skinned individuals afford protection against skin cancer due to melanin Increased likelihood of skin cancer in Whites than in Black and Hispanic populations Most important environmental risk factor for skin cancer is exposure to ultraviolet (UV) radiation both from sun and tanning sources Increased risk for melanoma related to increased number of sunburns during one’s lifetime Certain skin presentations associated with different ethnic groups 8 Copyright © 2016 by Elsevier, Inc.

MALIGNANT SKIN LESIONS Basal cell carcinoma Most common form of skin cancer Basal cell carcinoma begins in the basal cells. Deepest layer of the epidermis, known as the basal layer, contains basal cells. Starts as papule. Develops rounded borders w central red ulcer or large open pore. Most commonly affects areas of the body exposed to environmental factors including the face, ears, neck, scalp, shoulders and back. Squamous cell carcinoma Second most common skin cancer Squamous cell carcinoma affects the squamous cells---flat cells found in and just under the outer most layer of the epidermis known as the stratum corneum. Develops central ulcer w surrounding erythema… commonly found on the face, head, ears, lips, back of hands and neck, can also occur in scars and skin ulcers in other parts of the body, as well as in the genital area.

HEALTH HISTORY Copyright © 2016 by Elsevier, Inc. All rights reserved. Copyright © 2012,

SUBJECTIVE DATA HEALTH HISTORY QUESTIONS Past history of skin disease, allergies, hives, psoriasis, or eczema? Change in pigmentation or color, size, shape, tenderness? Excessive dryness or moisture? Pruritus or skin itching? Excessive bruising? Rash or lesions? Medications: prescription and over-the-counter? Hair loss? Change in nails’ shape, color, or brittleness? Environmental or occupational hazards? Self-care behaviors? 34 Copyright © 2016 by Elsevier, Inc. All rights reserved. Copyright © 2012, 2008, 2004, 2000, 1996, 1993 by Saunders, an affiliate of Elsevier Inc.

HEALTH HISTORY QUESTIONS CONT’D For the Aging Adults… § § § What changes have you noticed in your skin in past few years? Any delay in wound healing? Any change in feet: toenails, bunions, wearing shoes? Falling: bruises, trauma? History of diabetes or peripheral vascular disease? Do you do anything to care for your skin? 35 Copyright © 2016 by Elsevier, Inc. All rights reserved. Copyright © 2012, 2008, 2004, 2000, 1996, 1993 by Saunders, an affiliate of Elsevier Inc.

OBJECTIVE DATA: PHYSICAL EXAMINATION AND FINDINGS Preparation § Consciously attend to skin characteristics; the danger is one of omission Equipment needed: tape measure, pen light, gloves Copyright © 2016 by Elsevier, Inc. All rights reserved. Copyright © 2012, 2008, 2004, 2000, 1996, 1993 by Saunders, an affiliate of Elsevier Inc. 36

COMPLETE PHYSICAL EXAMINATION THOUGHTS… Skin assessment integrated throughout examination Scrutinize the outer skin surface first before you concentrate on underlying structures Separate areas with skinfolds such as under large breasts, obese abdomen, and groin, and inspect them thoroughly § These areas are dark, warm, and moist and provide perfect conditions for irritation or infection Always inspect feet, toenails, and between toes 37 Copyright © 2016 by Elsevier, Inc. All rights reserved. Copyright © 2012, 2008, 2004, 2000, 1996, 1993 by Saunders, an affiliate of Elsevier Inc.

THOUGHTS CONT’D… Individuals may seek health care for skin problems and assessment focused on skin alone Assess skin as one entity; getting overall impression helps reveal distribution patterns Inspect lesions carefully With a rash, check all areas of body as you cannot rely on the history that rash is in only one location Skills used are inspection and palpation because some skin changes have accompanying signs that can be felt 38 Copyright © 2016 by Elsevier, Inc. All rights reserved. Copyright © 2012, 2008, 2004, 2000, 1996, 1993 by Saunders, an affiliate of Elsevier Inc.

INSPECTION AND PALPATION: SKIN Color § General pigmentation, freckles, moles, birthmarks § Widespread color change § Note color change over entire body skin, such as pallor (pale), erythema (red), cyanosis (blue), or jaundice (yellow) § Note if color change transient or due to pathology § Vascularity or bruising: Multiple bruises at different stages of healing and excessive bruises above knees or elbows should raise concern about physical abuse § Needle marks or tracks from intravenous injection of street drugs may be visible on antecubital fossae, forearms, or on any available vein Temperature § Use backs of hands to palpate person § Skin should be warm, and temperature equal bilaterally; warmth suggests normal circulatory status § Hands and feet may be slightly cooler in a cool environment § Hypothermia § Hyperthermia 39 Copyright © 2016 by Elsevier, Inc.

All rights reserved. Copyright © 2012, 2008, 2004, 2000, 1996, 1993 by Saunders, an affiliate of Elsevier Inc.

INSPECTION AND PALPATION: HAIR Color § Due to melanin production Texture § Characteristics range from fine to thick to curly to straight and may be affected by use of hair care products Distribution § Scalp, face, body? . . . absence of, thick/thin Lesions § Identification by looking at scalp and dividing hair into sections 41 Copyright © 2016 by Elsevier, Inc.

INSPECTION PALPATION: NAILS Shape and contour: Profile sign: view index finger at its profile and note angle of nail base; it should be about 160 degrees Cleanliness Texture: smooth, ridging, brittle, splitting Thickness: should be uniform (check toes) Adherence: firm, not spongy Color: usually pink, dark skinned people may have brown/black linear bands Capillary refill: Depress nail edge to blanch and then release, noting return of color; indicates status of peripheral circulation § Color return is normally instant. Sluggish color return takes longer than 1 or 2 secs 42 Copyright © 2016 by Elsevier, Inc. All rights reserved.
