of the skin
Psoriasis is an inflammatory disease of the skin,
the nails, and sometimes the joints. As it affects
approximately 2% of the population, it is one of
the most common diseases seen by dermatologists.
Psoriasis most often appears between the ages of
20 and 30, but can begin at any age. For most people,
psoriasis is a lifelong disease that can be controlled
with proper treatment but not cured.
Skin lesions usually
look like round, red, scaly plaques. They most commonly
appear on the elbows, knees, scalp, and lower back,
but may occur anywhere on the skin. Most often only
a few small places on the body are involved, but occasionally
most of the skin surface is involved. In some people
the lesions come and go, whereas in other people the
lesions are stable or even spread over time. Trauma
to the skin can cause new lesions to form. Psoriasis
of the skin can have a negative impact on one’s
quality of life not only because of the appearance
of the skin lesions, but also because the lesions are
A common skin disease that causes redness and
swelling on the face. Often referred to as "adult
acne," rosacea may begin as a tendency to flush
or blush easily, and progress to persistent redness
in the center of the face that may gradually involve
the cheeks, forehead, chin, and nose. It also may
involve the ears, chest and back. As the disease
progresses, small blood vessels and tiny pimples
begin to appear on and around the reddened area;
however, unlike acne, there are no blackheads.
Seborrheic dermatitis is a common skin disorder that
can be easily treated. This condition is a red, scaly,
itchy rash most commonly seen on the scalp, sides of
the nose, eyebrows, eyelids, skin behind the ears,
and middle of the chest. Other areas, such as the navel
(belly button), buttocks, skin folds under the arms,
axillary regions, breasts, and groin, may also be involved.
