Discoid Eczema
Discoid
Eczema
(Alternative Names: Nummular Eczema,
Nummular Dermatitis, Discoid Dermatitis, Orbicular Eczema; nummular meaning coin and discoid meaning disc shaped)
Eczema is a broad term used to
describe redness, swelling, pain, and increased warmth of superficial layers of
skin. Usually eczemas are itchy but these may or may not be dry. Discoid or
Nummular eczema is a long duration variety of eczema in which initial lesions
are coin or disc shaped having alternate cycles of healing and activity.
Discoid Eczema is distinct as it arises
without a known cause, runs a prolonged course, and has no permanent cure. However,
it responds favorably to simple measures and most patients can help themselves
to a great extent with adequate knowledge and support.

Features,
Self Help, & Preventive Measures
Discoid Eczema manifests initially as
round or oval patches on the trunk and limbs that usually have the size of a
coin and are studded with small bumps with variable scaling or oozing. The intensity
of itching in patches is variable. Early lesions of DE might appear on one side
of the body but they often involve the other side of body and show tendency to enlarge, merge, or even show central clearing.
The areas in between the lesions have a normal looking skin. These lesions may
show recovery which is often followed by reactivation. Laboratory
investigations are not generally required except to rule out certain conditions
and to assess health status in general.
Tap water compresses are helpful in most
cases. Compression is done by using a moistened cloth kept over lesions for
15-20 minutes three to four times daily after squeezing out excess moisture. Emollients
are quite effective for relief in active disease. Usefulness of emollients
extends beyond the period of activity to later when they help in prevention.
When the lesions are active, emollients can be used every two to three hours in
liberal quantity. Emollients are applied gently to cover the area without
rubbing and are best applied in the direction of hair growth. To enhance their
efficacy, emollients may be used just after a bath or compresses. Another way
to make them work even better is to cover the skin for some hours with
occlusive dressing after applying the emollient or an emollient containing medication.
Steroids are effective in discoid eczema
but these should be used only under supervision and for specified duration only.
Immunomodulators alter our body’s response to the disease. Externally used
Immunomodulators have been successful in helping patients of DE. Other treatments include Ultraviolet light, immunosuppressant
drugs, and biological agents.
Effective measures are available to help
cope better with active phase and prolong period in between two episodes of
Discoid Eczema. Most such measures can be adopted by any one.
1. Consider
quitting alcohol.
2. You
can observe and attempt to pinpoint any triggers like injury, insect bites, and
other skin conditions that might be playing a role in precipitating relapses.
Once identified, suitable action can be taken to control them.
3. You
should pay attention to blood circulation in your limbs.
4. You
can fare better if you maintain a good personal hygiene.
5. Keep
your skin adequately moisturized. If a moisturizer is not available, you can
consider using lukewarm water with or without compresses.
6. Contact
your health service provider at the first signs of a recurrence as you might
need medicines essential to control the disease that are not available without
prescription.
7. Do
not use harsh detergents and soaps.
8. Always
keep your hands clean and fingernails short.
9. You
might consider joining a support group.
