Saya lampirkan artikel tentang Hemangioma, semoga bermanfaat.
Alternative names:
strawberry nevus; cavernous hemangioma
Definition:
Hemangiomas are abnormally dense collections of dilated small blood
vessels
(capillaries) that may occur in the skin or internal organs.
Causes, incidence, and risk factors:
The classically recognized hemangioma is a visible red skin lesion
that may
be superficial in the skin (in the top layers, called a capillary
hemangioma),
deeper in the skin (cavernous hemangioma), or a mixture of both.
Hemangiomas are usually present at birth although they may appear
within a
few months of birth often beginning at a site that has appeared
slightly dusky
or colored differently than the surrounding tissue.
Hemangiomas, both deep and superficial, undergo a rapid growth phase
in
which their volume and size increase rapidly. This phase is followed
by a rest
phase, in which the hemangioma changes very little, and an
involutional
phase where the hemangioma undergoes spontaneous regression. During
the
involutional phase, hemangiomas may disappear completely. Large
cavernous
hemangiomas distort the skin around them and despite full
involution, will
ultimately leave visible changes in the skin. The more superficial
capillary
hemangioma may involute completely, leaving no evidence of its past
presence.
Hemangiomas may be present anywhere on the body. However, they are
most disturbing to parents when they are on the infant's face or
head.
Hemangiomas of the eyelid may interfere with the development of
normal
vision and must be treated in the first few months of life. On rare
occasions,
the size and location of hemangiomas may interfere with breathing,
feeding, or
other vital functions. These lesions also require early treatment.
Large cavernous hemangiomas may develop secondary infections and
ulcerate. Bleeding is not uncommon and may be significant following
injury to
the hemangioma.
Prevention:
There is no known way to preventi hemangiomas.
Symptoms:
red to reddish purple raised vascular lesion on the skin
possibly massive, markedly elevated vascular tumor
Signs and tests:
Hemangiomas are diagnosed by physical examination. In the case of
deep or
mixed lesions a CT scan or MRI scan may be performed to ensure that
deeper structures are not involved. On occasion, hemangioma may be
associated with other rare syndromes. Additional studies may be done
to
determine if any of these syndromes are present.
Treatment:
Superficial or "strawberry hemangiomas" often are not treated as
treatment
may leave a cosmetic defect, letting the lesion to undergo
spontaneous
involution produces normal-appearing skin. In some cases, a laser
may be
used to eradicate the small vessels. Cavernous hemangiomas that
involve the
eyelid and obstruct vision are generally treated with injections of
steroids or
laser treatments that rapidly reduce the size of the lesions,
allowing the
development of normal vision.
Large cavernous hemangiomas or mixed hemangiomas, when appropriate,
are
treated with oral steroids and injections of steroids directly into
the
hemangioma. Recently, lasers have been used to reduce the bulk of the
hemangiomas. Lasers emitting yellow light can selectively damage the
vessels in the hemangioma without damaging the overlying skin. YAG
lasers
spare the skin by treating the hemangioma from within using a glass
fiber
delivery system. Some physicians are using a combination of steroid
injection
and laser therapy together.
Expectations (prognosis):
Small superficial hemangiomas should involute completely. Large
cavernous
hemangiomas should be evaluated by a physician and treated
appropriately.
Complications:
bleeding, perhaps to the extent of hemorrhage
visual abnormalities (amblyopia, strabismus)
psychosocial problems
Calling your health care provider:
All birthmarks, including hemangiomas, should be evaluated by the
health
care provider during a routine examination.

Secara ilmiah saya sendiri belum mendapat penjelasan tentang apa dan kenapa
hemangioma itu bisa ada. Seperti anda, saya juga berharap ada rekan-rekan
yang mengetahui dan bisa menginformasikannya pada kita melalui milis ini.
Mudah-mudahan pengalaman yang saya bagi ini bermanfaat bagi anda.
