Skin surface microscopy first started in 1663. The
very first dermatoscopic study was done by Johan Kolhaus
who first looked at nail fold vessels in a living
being with a microscope. In 1878 Abbe improved the
technique of skin surface microscopy by using immersion
oil between the lens and the skin to improve the image
clarity. Later, Unna published a paper in 1893 entitled ‘‘Diaskopie,’’ which
described how immersion oil was actually used together
with a microscope for skin surface microscopy.
The
German dermatologist, Johann Saphier, was the first
to add a built-in light source to the dermatoscope
instead of relying on an external light source. In
1920 and 1921 Saphier published several papers using
his invention and used the term “dermatoskopie” for
the first time. In the 1950s, Goldman was the first
dermatologist to coin the term "dermascopy" in
the English language. He was also the first to use
a dermatoscope to evaluate melanocytic nevi and melanoma
pigmented lesions – which is the primary use
for dermatoscopes today.
However, dermatoscopy took a long time to really
catch on and it wasn’t until the 1970s when
dermatoscopy and the use of dermatoscopes found a
following among a number of dermatologists. In 1971
Mackie reported on the improvement of the preoperative
diagnosis of pigmented lesions with the use of surface
microscopy. Following from this several authors, including
Fritsch, Pechlaner, Pehamberger, and Soyer, published
articles on dermoscopy in the 1980s and how dermatoscopes
could be used in routine diagnosis in a dermatology
clinic.
In 1989, a consensus conference was held by
the Committee on Analytical Morphology in Hamburg,
Germany, to develop standardized terminology for
the dermatoscopic technique with the results published
in 1990. From the 1990s onwards several dermatology
research groups developed several different diagnostic
methods for analyzing dermoscopic images. At the
same
time hand held dermatoscopes became widely commercially
available for purchase enabling an increased uptake
in their use around the world.
In 2001, the California medical device manufacturer
3Gen eliminated the need for an immersion fluid with
the introduction of a dermatoscope with a polarized
light source. Now several dermatoscopes with polarized
light sources are available and this has greatly increased
their use. The results of the Consensus Net Meeting
on Dermoscopy were then presented at the First World
Congress of Dermoscopy in Rome in February, 2001.
This meeting further refined the definitions used
for dermatscopic structures and validated a two step
procedure to classify pigmented skin lesions.
Since 2001, the dermatoscope has gained more popularity
and can be found in many larger dermatology clinics
around the word. There is still some resistance to
the “new” tool and some older dermatologists
still prefer to examine the skin without using a dermatoscope.
It must also be said that dermatoscope use is more
prevalent in Europe than it is in North America. Gradually
though the dermatoscope is becoming more popular.
