SKIN
TUMORS,
WARTS AND SARCOIDS
This
group of tumors has long caused confusion amongst
laymen and vets. This
is an interesting article:
When
is a wart a wart and when is it a sarcoid.
WARTS
Warts should be defined as the infectious disease
cutaneous papillomatosis, which occurs in young horses.
The
warts (papillomata) appear on the nose and, less commonly,
on other parts of the body, as small, hard, raised lumps, varying
in number from a few to many hundred.
The
disease is caused by a virus which
is specific to the horse.
The
precise method of infection is unknown, but it seems likely
that the virus gains entry through insignificant skin abrasions.
The young horse's habit of nuzzling various objects could result
in small skin wounds which, in turn, could lead to infection
and would then explain the high incidence of warts on the muzzle.
The
disease is self-limiting, and the warts, if left undisturbed,
disappear 3 to 4 months after their first appearance.
SARCOIDS
Sarcoid's are not as easy to explain, either their
cause or their make up. It is considered by some researchers
that they are an exuberant growth of normal skin tissue, other
researchers believe that sarcoids are
neoplastic. [ An abnormal new growth of tissue in animals; a tumor.]
The
present view is that sarcoids are, in fact, locally invasive,
non-spreading tumors of the skin. At first they look like a
wart, but as they grow the skin covering the sarcoid becomes
thin and breaks, allowing an ulcer to develop Sarcoids can
occur anywhere on the body, either singly or at multiple sites
and seldom undergo spontaneous remission.
They
are notoriously difficult to treat as they have a tendency
to recur when removed by surgery. They should be treated with
caution and it is unwise to consider purchasing a horse that
has sarcoids.
The
causal agent is again considered to be a virus but the interrelationship
of virus and tumor is still not understood.
Note:
The
above sentence tells us that this is viral based. Since Transfer
Factors are successful with [cancers:
especially those thought to have a viral epidemiology] and [viruses:
papova viruses -Any of a group of DNA-containing viruses that
are associated with or cause papillomas or polyomas in animals.] this
tells me the TF Animal Stress
Packs and TF Performance and
Show will address both no matter which one is the culprit.
But
the tricky part is how much and for how long. The more
chronic the problem the longer it will take to see results
but from many reports we have coming in it weeks all all
three problems some drop off quickly and some take some
time. But you must give the body the chance to use the
TF to fight the problem.

It
is possible that sarcoids develop as a result of earlier nonproductive
infection with the virus that causes juvenile warts or due
to infection with the virus that causes warts in cattle.
We
know that after the inoculation of young horses with an extract
of bovine papilloma virus, a sarcoid-like growth appears at
that site.
Treatment
of sarcoids is difficult. Where the site allows, surgical removal
is the easiest method, but up to 50 per cent of sarcoids recur
after surgical excision. Cryosurgery is a better technique.
The method generally used is to freeze the tumor with a liquid
nitrogen spray or probe. The frozen tumor sloughs away and
healing takes place over a period of three to eight weeks.
Radiation
techniques have been developed at several specialized centers.
Radioactive iridium pins or gold dust are implanted into the
tumor mass and over the next 6 to 12 months the tumor gradually
disappears. This method of treatment is especially valuable
where surgery, either normal or cryo, cannot be performed because
of the position of the tumor. Tumors around the eye are an
example.
Another
method that has been developed to treat this type of sarcoid
is the use of the human BCG vaccine. Normally used to vaccinate
children against tuberculosis, it also has the property of stimulating
local cell immunity.
Note: These
4 words above "stimulating local cell immunity" this
vaccine is successful because it does the very thing our
patented Transfer Factor Equine Products do! except TF does
it naturally.
When
it is injected into the base of a sarcoid the local reaction
kills the tumor cells and the tumor starts to regress. Several
treatments are needed before regression is complete and occasionally
a severe reaction at the site of injection complicates the
procedure.
MELANOMA
This unpleasant tumor is found in the gray horse. It
is a tumor of the melanin producing cells and can develop anywhere
on the body, although the area under the tail and on the perineal
area (between the anus and genital organs in the male, anus and
udder in the female) and perianal regions are common sites. Melanomas
are frequently multiple and are first seen as small, firm, black
lumps in the substance of the skin.
They
develop in three different ways. The most common pattern is
a constant, slow growth over many years. The tumors remain
local and do not metastasize (spread to other sites) but as
they get larger the skin covering them becomes damaged and
ulcers develop on the surface.
The
least common type is the tumor that is malignant from the start.
This type quickly invades local tissue and spreads to nearby
lymph nodes and from there to the lungs, liver and other organs.
The
third type of melanoma is that which has been quietly growing
for many years and then suddenly becomes malignant and rapidly
spreads through the body. Surgery is the only method of treatment
and this should not be undertaken lightly. The only type of
tumor that is worth removing by surgery is the single tumor
that shows no sign of malignancy and even these tend to have
seeded before removal.
SQUAMOUS
CELL CARCINOMA
These tumors are malignant and appear on the surface
of mucous membranes. They comprise the second largest group of
tumors affecting horses and involve the eye and associated structures,
the penis and sheath in males, and the vulva in females. The
tumor spends a long time invading the local tissues before it
spreads to other parts of the body. This allows effective surgical
removal to be carried out. "
