List the 13 lesions that can occur with AE |
Macule Papule Vesicle Pustule Exudation and crusting Excoriation and erosion Fissuring Scaling Lichenification White dermographism Hyper and hypo pigmentation Atrophy Nodules |
|
|
Macule |
Red macules are almost always present, often forming the background to the other lesions. Dark skin appears hyper-pigmented |
|
|
Papule |
Tiny red papules tend to form very quickly, often merging together to for edematous plaques |
|
|
Vesicle |
Thin walled vesicles, with an erythramatose base are relatively infrequently seen on the body, although typically found between the fingers, on palms and soles. Vesicles or eroded vesicles are also seen in eczema herpaticum. |
|
|
Pustules |
Folliculitis. Also associated with overt infection. Over use of greasy emollients may also predispose to foliculitis. Long term use of potent topical, inhaled, or oral steroids can lead to acne like eruption |
|
|
Exudation and crusting |
Either bloody or yellow crusting follow exudation. In some cases where bacterial infection is pronounced, the crusts can be very marked |
|
|
Excoriation and erosion |
Common outcome of severe scratching and itching |
|
|
Fissuring |
Dryness with fissuring is often intermixed with other lesions |
|
|
Scaling |
Often forms part of the picture. Can be especially pronounced following an active inflammatory phase. In erythroderma the scaling typically becomes more pronounced, often fine and powdery, though sheet-like scaling also occurs. |
|
|
Lichenification |
Is often pronounced especially around the flexures. Acute attacks of eczema with the characteristic papulovesicles may coexist with area of lichenification. Lack of ability to form lichenified areas in severe eczema is a poor prognostic sign |
|
|
White dermographism |
On rubbing or scratching the skin, white lines appear instead of the normal Triple Response of Lewis |
|
|
Hyper and hypo pigmentation |
Aftermath of inflammatory lesions |
|
|
Atrophy |
Common following repeated use of systemic steroids or longterm application of topical steroids |
|
|
Nodules |
Relatively uncommon. Seen in some severe forms |
|
|
What is the Triple Response of Lewis? |
1. If you rub the skin it will tuen red 2. Then flare (in eczema patients instead of red dermographism (blood vessels expanding), they have white dermographism (constriction of superficial plexus, dilation of deep plexus) 3. Wheal |
