The
Condition
This
procedure involves taking a sample of a skin tissue then
processing it and examining it under a microscope. There
are various ways in order to get a hold of a skin sample.
This procedure would depend on the size and location of the
area involved or what we call a skin lesion. The skin
sample obtained will be placed in a solution, for instance
formaldehyde, and then the tissue is processed and examined
under a microscope. If infection is suspected, the skin
sample would then be placed in a sterile container.
When
an area of the skin is suspected of any abnormality or when
there have been changes in the color, shape, size, or
appearance of an area of the skin and has not healed after
an injury, skin biopsies are done. These are often used in
diagnosing skin cancer, which is the most common type of
cancer. Identification of skin cancers can be achieved
through early diagnosis of a suspicious skin lesion and
through a skin biopsy, thus leading to an early treatment.
A skin
biopsy is used to diagnose skin conditions, especially if it
is not clear as to what the condition is, such as
psoriasis. Diseases, such as skin cancers also make use of
a skin biopsy. It is also done to diagnose bacterial or
fungal skin infection.
After
undergoing skin biopsy, a dressing will be applied over the
biopsy site and an antibiotic ointment if no stitches were
used. It is advisable to clean the area, re-apply the
ointment, and change the dressing once or several times a
day until healing of the area biopsied is achieved. Healing
usually takes 5 to 28 days depending on the size and
location of the biopsy. It is important that you do not let
the biopsied area dry out as formation of a scab will result
in delayed healing.
On the
other hand, a dressing is usually left in place or
occasionally changed once the stitches are removed which is
usually 5 to 10 days after doing the biopsy, again,
depending on the size and location of the incision. At this
time, the area should remain dry. If there is any bleeding,
swelling, or abnormal redness or pain, it should be reported
right away. Activities such as exercising or heavy lifting
are also not advisable for several weeks.

Frequently Asked
Questions
Q:
What are the advantages and disadvantages of getting a skin
biopsy?
A:
A skin biopsy can be a very informative procedure since it
can provide both a diagnosis and treatment for a certain
condition. The disadvantages, on the other hand, are that
this procedure is invasive and most of the time follow-up
care is necessary.
Q:
What are the risks associated with a skin biopsy?
A:
Some of the risks are infection and persistent bleeding
although this is unlikely to occur. Scar formation at the
biopsy site may also occur if you are prone to form scars
after a skin injury or surgery.
Q:
What affects the skin biopsy procedure?
A:
Some medications, such as anti-inflammatory medications,
antifungal medications, and corticosteroid skin creams, can
get in the way of the biopsy or interfere with the accuracy
of the results.
Q:
How would I feel after undergoing a skin biopsy?
A:
Several days after a skin biopsy, the biopsy site may feel
sore and may bleed slightly. Make sure that you inquire
from your doctor on how bleeding or other drainage is
anticipated. It is very important that you contact you
doctor right away if you experience the following:
-
Too much bleeding or drainage through the bandage. When
this happens, pressure must be applied to the biopsy
site and call your doctor right away.
-
The biopsy site shows increased redness or swelling and
increased tenderness and pain is felt.
-
Presence of a fever.
