DERMOSCOPY and Mole Surveillance


This involves observing flat and some elevated lesions of the skin with much more detail and accuracy.  It incorporates a magnifying glass (usually 10x) and a polarised light, which stops the glare (light reflection) from the surface of the skin, allowing a clearer view of the lesion.

Some important diagnostic features of skin lesions are not apparent to the naked eye, but show up clearly when examined with this device.  Therefore Dermoscopy has now become a useful adjunct to the assessment of skin lesions, helping to make the correct diagnosis or exclude malignancies.  Its use can result in far fewer unnecessary biopsies.

Some instruments need the use of placing a drop of oil on the skin to allow examination.  Other more modern instruments do not need this and are simply used as hand held magnifiers.  I use this type of instrument, with the advantage that numerous lesions (e.g. moles) can be examined rapidly as in mole surveillance procedures.
