Lupus
Pregnancy (EAC usually disappears/stops soon after delivery of baby). Hormone (Contraceptive Pill, Stress, Hormone Drugs)
Lyme disease

Diagnosis
A skin biopsy can be performed to test for EAC; tests should be performed to rule out other possible diseases such as: pityriasis rosea, tinea corporis, psoriasis, nummular eczema, atopic dermatitis, drug reaction, erythema migrans and other rashes. Differential diagnosis
Sarcoidosis
Fungal infection
Lupus erythematosus

Treatment
No treatment is usually needed as they usually go away anywhere from months to years. The lesions may last from anywhere between 4 weeks to 34 years with an average duration of 11 months. If caused by an underlying disease or malignancy, then treating and removing the disease or malignancy will stop the lesions. It usually doesnt require treatment, but topical corticosteroids may be helpful in reducing redness, swelling and itchiness. Some supported and not supported methods of having an effect on EAC include:

Photosensitive so it can be moved/reduced with appropriate sunlight. Vitamin D
Immune system - hence it will increase in size/number when the immune system is low or overloaded. Hormone Drugs
Disulone
Stress reduction
Topical calcipotriol - a topical vitamin D derivative has been known to be beneficial

Epidemiology
It is very rare and estimated to affect 1 in 100,000 per year. Because of its rarity the documentation, cases and information are sparse and not a huge amount is known for certain, meaning that EAC could actually be a set of many un-classified skin lesions. It is known to occur at all ages and all genders equally. Some articles state that women are more likely to be affected than men.
Minutes, also known as minutes of meeting (abbreviation MoM), protocols or, informally, notes, are the instant written record of a meeting or hearing. They typically describe the events of the meeting and may include a list of attendees, a statement of the activities considered by the participants, and related responses or decisions for the activities. Etymology
The name "minutes" possibly derives from the Latin phrase minuta scriptura (literally "small writing") meaning "rough notes". Creation
Minutes may be created during the meeting by a typist or court reporter, who may use shorthand notation and then prepare the minutes and issue them to the participants afterwards. Alternatively, the meeting can be audio recorded, video recorded, or a groups appointed or informally assigned secretary may take notes, with minutes prepared later. Many government agencies use minutes recording software to record and prepare all minutes in real-time. Purpose
Minutes are the official written record of the meetings of an organization or group. They are not transcripts of those proceedings. Using Roberts Rules of Order Newly Revised (RONR), the minutes should contain mainly a record of what was done at the meeting, not what was said by the members. The organization may have its own rules regarding the content of the minutes. For most organizations or groups, it is important for the minutes to be terse and only include a summary of the decisions. A verbatim report (transcript) is typically not useful.
