1
Q
For Soft Tissue Lesions
(3)
A
- Texture/ Consistency
- Association with surrounding tissue
- Anatomic Location Changes DDx
2
Q
- Association with surrounding tissue
(2)
A
– Fixed vs. Moveable
– Displacing vs. devouring
3
Q
For White lesions
(6)
A
- Wipe first
- Sources of Friction
- Chemicals
- Heat
- Alter environment & Re-evaluate
- White lesions are mostly “low-risk” lesions
– But location matters

For Red Lesions
(5)
A
- Diascopy
- Location!
- Habits
- Trauma
- Medical History
– Coagulation

- Number
- Size
- Onset
– Speed
– Prodrome - Frequency/Duration
- Location
– Other areas of the body
8
Q
Vesicle
A
- A small circumscribed elevated lesion usually less than 1cm in
diameter, usually contains serous fluid
9
Q
Bulla
A
- Circumscribed elevated lesion that is around 1cm in diameter, usually
contains serous fluid
10
Q
Pustule
A
- Various sized circumscribed elevations containing pus
11
Q
Macule
A
- An area that is usually distinguished by a color different from that of
the surrounding tissue: It is flat and does not protrude above the
surface of the normal tissue.
12
Q
Papule
A
- A small circumscribed lesion usually less than 1cm in diameter that is
elevated or protrudes above the surface of normal surrounding
tissue.
13
Q
Nodule
A
- A circumscribed lesion usually greater than 1cm in diameter that is
elevated or protrudes above or below the surface of normal
surrounding tissue.
14
Q
Pedunculated
A
- Attached by a stem-like or stalk base
15
Q
Sessile
A
- Describing the base of a lesion that is flat stem-like
16
Q
Ulcer
A
- A loss of continuity of the epithelium that penetrates to the the
underlying connective tissue
17
Q
Plaque
A
- A patch or differentiated area on a body surface
