Etiology
The study of a disease is called?
Pathology
Causes by a harmful disease producing bacteria
Pathogenic disease
Structural changes in tissues caused by damage or injury. Any mark, symptom, or abnormality
Lesion
What are the three types of lesions?
Primary
Secondary
Vascular/Tertiary
Characterized by changes in color - macules, papules, or patches
They can even be an elevation formed by fluid in a cavity, such as a vesicle, blister (bullae), or pustules
Primary lesion
Light colored, slightly raised mark on skin formed after injury; tissue hardens to heal
Scars
Skin lesions that result when primary lesions undergo a natural evolution, or are manipulated by the patient. They may require treatment by a physician
Secondary lesion
Are usually blood related
- port wine stains
- spider naevi
Vascular/tertiary lesion
Why do estheticians need to recognize the various types of lesions?
To be able to identify certain conditions for proper referral to a physician.
