The lupus butterfly
rash, also called the malar rash, is probably the best
known characteristic of lupus. The lupus butterfly rash
may be one of the first signs that you may have lupus.
The malar rash occurs in about half of the patients with
SLE and is characterized by a butterfly-shaped red rash
that extends over the bridge of the nose and the cheeks.
The rash may be flat or raised. The malar rash often
appears or gets worse after sun exposure
(photosensitivity) or stress that causes an increase in
the circulation to the skin.
Sometimes the lupus butterfly rash appears on other
parts of the body as well, usually on the trunk, arms or
legs. The malar rash is normally is itch-free and
painless, although it may itch and cause a burning
sensation. Sometimes the malar rash accompanies a flare
(an active state of lupus). The malar rash may be the
first of
lupus signs and symptoms. It may be a sign that lupus is entering an
active phase or it may actually cause the disease to
attack other tissues in the body.
The lupus butterfly
rash can be as mild as a slight blush-like rash to a
severe, scaly rash. The butterfly rash may also be short
lived, or it may last for many months. The reason the
malar rash is shaped like a butterfly is because it
follows the angle that the UV rays land on the skin. The
malar rash is caused by a malfunctioning immune system
which causes the body to attack healthy tissues in the
skin.
The lupus butterfly rash was first described by the
Viennese physician Ferdinand von Hebra. He noticed a
butterfly-shaped rash on the cheeks and nose of lupus
patients in the 1840s. It is distinctive from the normal
sunburn or blush of the cheeks due to its tell-tale
shape and unique characteristics. It may be very faint
or it may be very obvious.
The
rash
lupus symptom can also be accompanied by
lupus
hair loss,
lupus fatigue or other
symptoms of this autoimmune disease.
To prevent the lupus butterfly rash from occurring, the
you should be sure to wear protective clothing when
outdoors, wear a wide-brimmed hat, avoid going out in
the sun when the sun is at its hottest (between 10:00
a.m. and 2:00 p.m.), always wear a wide spectrum
(protects against UVA and UVB rays) sunscreen of at
least an SPF (sun protection factor) of 30 whenever you
go outside, and use sun shades for windows.
If you experience a
butterfly-shaped rash over the bridge of your nose and
your cheeks, see your doctor. This may be a sign that
you have lupus. If you are already diagnosed with lupus, and
you develop the malar rash, you should tell your doctor
because this may be a sign that the disease is going
into an active phase. You should be aware of symptoms of
other lupus related problems as well so that these can
be treated before permanent damage can result. If you
have lupus, it is up to you to stay informed and aware
of any new symptoms and problems.
