  2. Skin Disorders • Cancer • Burns

  3. Skin Cancers • Over 1 million diagnosed each year • Arizonan’s have 3-7x more risk than people in other states • 3 common types • Melanoma • Basal cell carcinoma • Squamous cell carcinoma

  4. Melanoma • Most dangerous form of skin cancer • Appears as: • Change in existing mole • Small, dark multicolored spot with irregular borders, elevated or flat, bleed or form scab • Cluster of shiny, firm, dark bumps • Larger than a pencil eraser

  5. Melanoma • Benign – not cancerous • Malignant - cancerous

  6. Basal Cell Carcinoma • Come from cells in stratum basale of epidermis • Appear on sun-exposed skin as: • Pearly or flesh-colored oval bump with a rolled border, may develop into bleeding ulcer • Smooth red spot indented in center • Reddish, brown, or bluish black patch of skin on the chest or back

  7. Basal Cell Carcinoma

  8. Squamous Cell Carcinoma • Arise from squamous cells of epidermis • Arise from damaged tissue • Appear on sun-exposed skin as: • A firm, reddish, wart-like bump that grows gradually • Flat spot that becomes a bleeding sore and won’t heal

  9. Squamous Cell Carcinoma

  10. Symptoms • Any change in size, color, shape or texture of a mole or other skin growth • Open or inflamed skin wound that won’t heal • ABCD’S of melanoma • A – asymmetry • B – border • C – color • D – diameter

  11. Burns • 1st, 2nd, 3rd degree • Named according to severity • 1st degree • Least severe • Redness or discoloration • Swelling and pain • Usually overexposure to sun • Only epidermis is damaged

  12. Burns • 2nd degree • Affect epidermis and dermis • May blister • Scarring may result • Most painful because nerves are intact but tissue is damaged • May involve loss of skin function

  13. Burns • 3rd degree • Worst burn • May look white or charred • Extend through all skin layers – epidermis, dermis, subcutaneous layer • Severe to no pain depending on nerve damage • Requires skin grafts
