Description In this chapter we describe equipmentphysical item that can be used to achieve a goal, especially if the item is not consumed in the process for dermoscopyThe examination of [skin lesions] with a 'dermatoscope'. This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. examination including handheld dermatoscopes, systems for digital dermoscopyThis glossary term has not yet been described., attachments for smartphonesThis glossary term has not yet been described..

Handheld dermatoscopes

There many different types of handheld scopesThis glossary term has not yet been described.. There are scopes that use polarized lightThis glossary term has not yet been described. or standard LED light. There are scopes that allow to toggle from polarized to non-polarized mode. Some scopes can also be attached to a cameraA camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies (smartphoneThis glossary term has not yet been described. / tabletThis glossary term has not yet been described.).
It is the author's preference to use scopes that allow toggling between polarized and non polarized lightThis glossary term has not yet been described. because it provides additional information. When asked which scope is most recommended, the author's answer is - Try it out, hold it in your hand and see which ones feels best for you.

Here are some examples of handheld dermatoscopes that are currently on the market:


Systems for digital dermoscopyThis glossary term has not yet been described.

There are many different systems for digital dermoscopy on the market. Every system has different features, including Storage and retrieval of lesions (clinical and dermoscopy imagesA representation of a person, animal or thing, photographed, painted or otherwise made visible.); total body imagingThis glossary term has not yet been described.; and digital mole monitoringTaking sequential images of pigmentes lesions in order to be able to evaluate change over time..
In addition, some systems use computer assisted features:

  • Computer assisted total body imaging
  • Computer assisted diagnosisare systems that assist doctors in the interpretation of medical images. Imaging techniques in X-ray, MRI, and ultrasound diagnostics yield a great deal of information that the radiologist or other medical professional has to analyze and evaluate comprehensively in a short time. CAD systems process digital images for typical appearances and to highlight conspicuous sections, such as possible diseases, in order to offer input to support a decision taken by the professional. of dermoscopy images

  • Automated PASI calculation
  • 3D imagingThis glossary term has not yet been described.


Every system is very different than the otherThis glossary term has not yet been described., and the best thing is to try them out in real world conditions in order to find out if the workflow of the software is compatible with your individual workflow. Some examples include:



Cases for smartphones

Several companies provide Dermoscope cases adapt to a smartphone or a tablet that provide good image quality. The images can be stored on the phone in specific apps and then be transferred to the medical record or systems for digital dermoscopy.

Examples include:

Attachments (lenses) for digital cameras

Dermoscopic lenses that attach to digital cameras provide very high quality images. Examples include:

Full body imagingThis glossary term has not yet been described. systems

Apart from classic digital dermoscopic systems, there are vendors enabling the users to aquire and organise full body images in 2D or 3D. They are either integrated into digital dermoscopic systems, work with smartphones, or have a separate rigging system. Examples include:
