  1. Anatomy & Physiology Skin Abnormalities Skin Diseases

  2. Abnormalities • Papules • Firm, raised areas • Example = chicken pox, pimples • Macules • Flat spots on the skin • Example = freckles

  3. Abnormalities • Vesicles • Fluid (clear) filled blisters • Example = chicken pox • Pustules • Pus filled sac • Example = acne

  4. Abnormalities • Crusts • Areas of dried pus and blood (scab) • Wheals • Itchy, elevated areas (irregular shape) • Example = hives

  5. Abnormalities • Skin Ulcer • Deep loss of skin surface

  6. Condition of the Skin • Acne • Inflammation of the oil glands • Common among adolescence • Glands become blocked by oil & dirt http://www.emedicinehealth.com/acne/page10_em.htm

  7. Diseases • Athlete’s foot • Fungal infection • Affects feet : itchy, burning, skin blisters • Tx: antifungal med; keep feet clean & dry

  8. Diseases • Dermatitis • Inflammation of the skin • Caused by irritants • S&S dry skin, itchy, rash • Anti inflammatory cream, antihistamine meds

  9. Diseases • Skin cancer • Develops from a mole (change in size, shape, color) • Bleeding / Itching may occur • Risks = exposure to UV rays

  10. Diseases • Impetigo • Highly contagious skin infection • Caused by strep / staph • S&S erythema, pustules, yellow crust • Tx: wash lesions with soap & water; antibiotics

  11. Diseases • Psoriasis • Chronic, noncontagious disease • Inherited skin disorder • S&S thick red areas covered with silver scales • No cure • Tx: UV treatment

  12. Diseases • Ringworm • Highly contagious fungal infection • S&S flat or raised circular area (white center): itchy • Tx: antifungal med

  13. Diseases • Wart • Caused by a viral infection • Hard, elevated & round surface • Tx: may disappear spontaneously; removal (laser, chemical)
