Pigmentation is a congenital vascular lesion. Another name
for port wine stain is nevus flammeus. Port wine
stain is an irregularly shaped vascular malformation with
prominent deep layer dermal blood vessels that are oftentimes
present at birth and essentially do not disappear with time.
Generally, the malformation is confined to the skin. The color
of the port wine stain varies in hue from pink to red to purple.
The shape is irregular and generally the distribution is unilateral.
Most commonly, the face is involved but it may indeed incur
at any cutaneous site.
Pigmentation is the coloration of living tissues by pigment or, in other words it is the deposition of pigment in human beings. Some pigmentation problems are skin discolorations, appear as a blotchy, brownish pigmentation on the face and body. Skin discoloration is especially common in women aged 20-40.
The mainstay of therapy for pigmentation in todays
medical environment is the Candela flash lamp pulse dye laser,
which is specifically designed to treat vessels in the epidermis
and dermis of children and adults with Pigmentation. The
fancy nomenclature for laser treatment of Pigmentation
is selective photo thermal lysis, which simply
means that the laser will specifically treat the dilated vessels
and not injure the surrounding epidermis, dermis, and soft
tissue structures other than the vessels. Chomogenex pulse dye laser treatment of Pigmentation typically requires several
sessions, usually anywhere from one and ten. Treatment for
Pigmentation first requires performing a laser response
test, which determines the efficacy and response of an individuals
tissue to the laser. Several energy levels are tested and
evaluated approximately six weeks later.It is of significant
advantage to treat early on for a number of reasons; specifically,
the port wine stain is not hypertrophied, not as well matured,
and not as prominent.
Repeated pregnancies, can intensify the pigmentation. Sun exposure, following the use of deodorant soaps, scented toiletries, and various cosmetics can also produce this mottled pigmentation. This is called a phototoxic reaction and is due to ultraviolet radiation being absorbed by the chemical substance (perfume, cologne and other types of fragrance) on the skin. This pigmentation often extends down to the sun-exposed areas of the neck and may be more pronounced on the right side of the forehead, face and neck due to sun exposure while driving a car (or the left side - if you drive on the right).
