Cyst= filled with solid material!

Solid RAISED dome-shaped lesion with a smooth surface

Can have a palpable sac that the skin moves over

Q

What is scaling? (secondary)

  • Can be fine OR sheet like scaling

-Seen in papulosquamous conditions & ichthyoses

17
Q

What is Licenification? (secondary)

A

Thickening of the epidermis from external irritation

Something is rubbing up against the skin

18
Q

What is crusting? (secondary)

A

Dried collection of serum or cellular debris

Think it is crusted over!!

19
Q

What is a scar? (secondary)

A

Fibrous thickenings of the dermis resulting in loss of epidermal ridges.

Raised= hypertrophic
Flat

Thickened, firm & SOMETIMES DISCOLORED collection of connective tissue.

Caused by: Dermal damage

20
Q

What is excoriation? (secondary)

A

What we you see? Superficial linear erosion

Caused by: SCRATCHING- seen a lot because kids like to scratch!

21
Q

What is an ulcer? (secondary)

A

What do you see?

Deeper depression with the loss of the whole epidermis

What happens- ulcers can heal &

produce scars

Q

What is a fissure? (secondary)

A

Linear splits in the skin, seen as wedge shaped cracks through the epidermis narrowing in the dermis

Since the skin is cracked this can be PAINFUL TO PATIENTS!!!

23
Q

What is erosion? (secondary)

A

shallow depression with the loss of your superficial epidermis. This is not gone to the dermis

24
Q

What are the examples of secondary skin lesions?

A

Scaling
Lichenification
Crusting
Scar
Excoriation
Ulcer
Fissure
Erosion

25
Q

What is the difference between a pustule & a vesicle?

A
  1. A vesicle is clear tan colored & a pustule is pus filled with erythema
