Study Notes
- There are 5 types of eczema.
Atopic/Flexural Eczema
- This type affects flexural areas of the body.
Varicose Eczema
- This is a progression of atopic eczema.
- It is caused by venous incompetence, leading to blood leakage into the skin, resulting in irritation.
Seborrhoeic Eczema
- It is located in the center of the face and scalp
Discoid Eczema
- It manifests as coin-shaped lesions, typically on the legs.
Lichen Simplex Eczema
-
It results from scratching
-
Eczema can become secondarily infected in 4 ways.
Irritant Contact
- This can be caused by over-handwashing.
Allergic Contact Dermatitis
- This can be caused by make-up
Staphylococcus Aureus (Impetiginised Eczema)
- It is characterised by yellow crust and weeping.
Herpes Simplex (Eczema Herpeticum)
-
It is characterised by monomorphic lesions.
-
Eczema Management is done in 7 ways:
- Avoiding soap
- Using emollients such as soap substitutes and moisturisers
- Applying topical steroids
- Administering oral antibiotics
- Using antihistamines (sedatives)
- Applying wet wraps
- Administering acyclovir, if herpes simplex is suspected (eczema herpeticum)
-
A key clinical feature of psoriasis:
- Symmetrical, well-defined red plaques with a thick, silvery scale.
-
Common sites for psoriasis:
- Elbows
- Knees
- Back
-
There are 4 types of psoriasis:
- Vulgaris
- Guttate
- Erythrodermic
- Pustular
Psoriasis Vulgaris
- Consists of chronic plaque psoriasis.
- Presents as well-defined salmon pink plaques with silvery scales.
Guttate Psoriasis
- Presents as raindrop-size lesions.
- Often follows a streptococcal throat infection.
Generalised Pustular Psoriasis
-
Presents in the natal cleft and below the buttocks.
-
Psoriasis treatments (7) and branching purpose:
- Emollients/bath oils
- Vitamin D analogues (e.g., calcipotriol)
- Tar preparations
- Topical steroids
- Dithranol
- UVB, PUVA
- Systemic treatments: acitretin, methotrexate, cyclosporin, biologics
-
These treatments reduce the rate of skin production.
Lichen Planus
-
Appears as flat-topped violaceous papules on the skin.
-
Has a predilection for flexor surfaces (wrists) and the lower back.
-
There are 3 types of Lichen Planus:
- Papular
- Hypertrophic
- Macular + pigmented
-
Lichen planus can cause scarring on the scalp and fingernails.
