Document Summary
Biopsy is one of most common diagnostic tests in evaluation of skin lesions. Techniques include punch, incisional, excisional, and shave biopsies. Other diagnostic procedures include stains and cultures for fungal, bacterial, and viral infections. Health promotion activities for good skin health include asvoidance of environmental hazards, adequate rest and exercise, and proper hygiene and nutrition. Sun safety includes sun avoidance, especially during midday hours, protective clothing, and sunscreen. Actinic keratoses, basal cell carcinoma, squamous cell carcinoma, and malignant melanoma are problems associated with sun exposure. Skin cancer is the most common malignant condition. Patients should be taught to self- examine their skin monthly. The cornerstone of self-skin examination is the abcd rule. Asymmetry, border irregularity, color change/variation, and diameter of 6 mm or more. Risk factors for skin cancer include fair skin type (blonde or red hair and blue or green eyes), history of chronic sun exposure, family history of skin cancer, and exposure to tar and systemic arsenicals.
