Integumentary System

Skin Disorders and Diseases

contact dermatitis p 172
Contact Dermatitis (p 172)
  • Inflammation of the skin
  • Immune induced or irritating substance
pituitary tumors
Pituitary Tumors
  • Abnormal skin pigmentation
  • Deep bronze tan
  • Increase secretion of MSH: melanocyte-stimulating hormones
jaundice
Jaundice
  • Abnormal Skin pigmentation
  • Excess bilirubin in the blood. (Bilirubin is produced by the normal breakdown of red blood cells. Normally bilirubin passes through the liver and is excreted as bile through the intestines)i
  • Jaundice occurs when bilirubin builds up faster than the liver can break it down and pass it from the body.

Vitiglio:

    • loss of melanocytes
    • loss of color
decubitus ulcers
Decubitus Ulcers
  • Bed sores
  • Occurs from pressure on superficial blood vessels
  • Lack of circulation kills epidermal cells

(p172)

baldness
Androgenic alopecia

Associated with testosterone

Alopcecia areata

Blood makes antibodies that attack hair follicles

Causes: estrogen levels, medicines, high fever.

Baldness
skin cancers
Skin Cancers
  • UV radiations causes mutation in the DNA of a skin cell
  • 75% of cancers are skin cancers
  • Most common cancers are caused by prolonged exposure to UV radiation from sunlight
types of skin cancer
Types of Skin Cancer
  • Three major types:
    • Basal Cell Carcinoma
      • Most common type of skin cancer
      • 2/3 of these cancers appear from chronic UV exposure
skin cancer
Skin cancer
  • Squamous cell carcinoma
    • Frequent in light, pale skin over 40 years old
    • Slow growing
    • Surgical removal or radiation
skin cancer1
Skin Cancer
  • Malignant Melanoma
    • Arise from melanocytes
    • Usually in trunk of body and from a mole
    • Hard to treat
squamous cell carcinoma
Squamous Cell Carcinoma

Originates from epithelial cells

malignant melanoma
Malignant Melanoma

Difficult to treat due to fast growing and invasion of deep tissues

Risk increases with short, intermittent exposure to high-intensity sunlight.

Cyanosis

    • Bluish skin tint
    • Caused by severe reduction in blood flow or oxygenation
  • Jaundice:
    • buildup of bile produced by liver
    • yellow color
  • Addison’s disease:
    • and other diseases of pituitary gland
    • skin darkening
  • Vitiglio:
    • loss of melanocytes
    • loss of color
