Wheal – firm, edematous Pustule – elevated, superficial, filled with purulent fluid Nodule – elevated , solid, extends into dermis, circumscribed border, 0.5 – 2 cm Tumor – elevated, solid, extends into dermis, irregular border, greater than 2 cm Secondary Skin Lesions:  Secondary Skin Lesions Fissure – linear cracks Scale - excess shedding of dead keratinized tissue Scar – abnormal formation of connective tissue Ulcer – irregular, crater-like loss of epidermis & dermis Atrophy – depression in skin from thinning of the epidermis or dermis Excoriation – area where epidermis is missing, exposing dermis Nursing Diagnoses:  Nursing Diagnoses Impaired skin integrity Situational low self esteem Ineffective health maintenance Altered body image Social interaction, impaired Common Benign Conditions:  Common Benign Conditions Pruritis Psoriasis Acne Pruritis:  Pruritis Itching If a chronic problem… C/S of scrapings Fungal studies Cutaneous patch testing Pharmacology Antihistamines, Tranquilizers, and Antibiotics Pruritis:  Pruritis Nursing Intervention Therapeutic baths Aveno, colloid , alpha-keri Administer creams, pastes, or ointments Comfortable, cool room temperature Monitor skin for infection Psoriasis:  Psoriasis Chronic, noninfectious skin condition characterized by raised, reddened, round circumscribed plaques covered by silvery white scales. Size varies. Cause unknown; some evidence supports autoimmune. Stress, sunlight, hormonal fluctuations, and some medications can induce. Psoriasis:  Psoriasis Pharmacology Corticosteriods Tar preparations-suppress miotic activity Amevive (alefacept) injection- suppress rapid turnover of epidermal cells Antimetabolites (Methotrexate) Treatments Sunlight Ultraviolet Light Therapy-decreases the growth rate of epidermal cells ACNE:  ACNE Acne vulgaris effects 85%^ of the population. The peak incidence is age 17 to 18 years of age. Family history, premenstrual flares, and sometimes stress can cause a flare up. Cosmetics containing lanolin, petrolatum, vegetable oils, lauryl alcohol, butylsterate, and oleic acid can increase comedome production.

Skin Cancers:  Skin Cancers Non-Melanoma’s Basal cell carcinoma Squamous cell carcinoma Melanoma Basal Cell Carcinoma:  Basal Cell Carcinoma Most common malignant tumor in U.S. Originates from basal layer of epidermis Risk factors: UV exposure & severe sunburn in childhood or adolescence Usually found on head or neck, especially the nose Dome-shaped, flat, slightly red papule or macule, translucent, indistinct border, hard scale Squamous Cell Carcinoma:  Squamous Cell Carcinoma Malignant tumor of keratinocytes of skin & mucosal surfaces Actinic keratosis is precursor Second most common skin cancer in U.S. Can be aggressive & metastasize Found on head & neck (lips & mouth of smokers) Begins as firm, dull red keratosis & progresses to nodule which ulcerates & attaches to underlying tissue Actinic Keratosis:  Actinic Keratosis Basal & Squamous Cell Carcinomas:  Basal & Squamous Cell Carcinomas Malignant Melanoma:  Malignant Melanoma 55,100 new cases of invasive melanoma in U.S. per year (1 or 57 males & 1 of 75 females) Arises from melanocytes. 1/3 occurs in existing moles Most often found on chest & trunk on males & lower legs of females. Can form in eyes, mouth, vagina, & other internal organs. Signs & Symptoms of Melanoma:  Signs & Symptoms of Melanoma Asymmetry of mole- ½ doesn’t match the other Border irregularity - edges are ragged or notched Color – differing shades of tan, brown, black with sometimes patches of red, blue or white. Diameter – mole is wider than 6 mm (1/4 inch) Any change of a spot or bleeding from lesion Moles:  Moles GOOD BAD Melanoma:  Melanoma Risk factors:  Risk factors Congenital moles, large or numerous moles Fair skin that freckles, red or blond hair Family history of melanoma Immune Suppression Excessive exposure to UV radiation & sunburn Age & gender Treatment of Melanoma:  Treatment of Melanoma Biopsy of skin & underlying tissue if necessary Wide, local incision to remove all of lesion Wedge resection of earlobe Amputation of fingers or toes Wide resection of sole of foot Thickness of lesion & ulceration are strongest prognostic features Prognosis :  Prognosis Patients treated early with removal of total lesion have 100% cure rate. Patients who have metastasis to the lymph nodes have 50% survival rate after 5 years following treatment. Patients who have systemic metastasis can live 6-9 months after treatment Nursing Intervention:  Nursing Intervention Teaching prevention Teaching ABCD’s Support patient receiving chemotherapy Routine post-op care Support the patient & family emotionally to decrease fear, and low self-esteem if body image is altered.
