This slide
shows a
tumor
metastasizing,
or breaking up
and traveling
to different
parts of the
body .
Basal Cell Carcinoma – the most common
type - up to 90% of all skin cancers are this.
This is another basal
cell carcinoma.
They typically start
as a shiny bump,
then slowly grow
and form disfiguring
masses. They
seldom metastasize.
Removal is done
surgically, and only
require radiation in
tough to treat cases.
When left untreated,
basal cell
carcinomas can
cause great
disfigurement.
Surgical removal will
leave large
depressions in the
skin’s surface.
The dark area in the
center of this circle
is a squamous cell
carcinoma. After
surgical removal,
this patient will
receive radiation
treatment. Between
1500 and 2000
people die from this
type of cancer each
year.
This girl has a squamous cell carcinoma.
People with high melanin content are not
immune to skin cancers!
This is an example of melanoma or
malignant melanoma. This is the most
dangerous form, and also the most rare.
The ABCD Rule of Melanoma
• A = Asymetry – one half of the mole does
not match the other
• B = Border Irregularity – the edges of the
mole are uneven, notched or blurred
• C = Color – the pigment is not even.
Cancerous moles may have several colors
in one mole (blue, red, brown or black)
• D = diameter - watch moles the size of a
pencil eraser or larger for changes.
This melanoma grew under this man’s
fingernail. The nail has been removed to
facilitate removal of the tumor.
The large brown
mass on the side of
this woman’s nose
is a malignant
melanoma.
This is the same
woman. Her
melanoma has been
removed. If you
look closely, you
can see the
depression where
the tumor once was
located.
This is a further
close-up of the
woman’s scar.
Doctors found that
her cancer had
spread, so she
underwent
chemotherapy to try
to obliterate all of
the cancerous cells.
The differences in
the woman’s
appearance are side
effects of the
chemotherapy.
This woman has a small melanoma on her
neck.
The “peeling” that
you see on this
woman’s legs is the
result of melanoma
that metastasized
through her lymph
system. She began
chemotherapy
treatments soon
after this photo.
This is one of several melanomas on this
man’s face.
This is another
melanoma on this
girl’s leg. Notice
how large and
irregular it is.
With this close-up, the asymmetry is easy to
see.
Although it looks
like a bruise, this
man has an
advanced
melanoma on his
eyelid.
This woman has many melanoma tumors
on her back. She is 49 years old.
Again, a close up. If you’re not in the habit
of checking your back, have a family
member do it for you yearly.
It’s hard to see what
is wrong with this
woman. There is a
melanoma on the
left side of her nose
in this picture.
Although it’s not
dark, the tumor is
still melanoma.
The woman’s
nose had to be
removed
because the
cancer was so
advanced. The
pen marks are
guides for
radiation, while
the mouth cork
is to keep her
airway open.
Historical Comparison of Melanoma Cases
This is not a color
enhanced photo.
This woman did not
read the warnings
on her medicine.
She went to the
tanning bed while
taking tetracycline.
This antibiotic
amplifies the effects
of UV light.
Immunological factors and UV light: normal
epidermal Langerhans cells on the left;
there are fewer cells on the right after being
treated with UV light.
