A dermatoscope is a hand-held skin surface microscope with approximately 10 x magnification (Fig.1). The skin surface is illuminated by a halogen bulb powered with batteries or a rechargeable system built in the handle. By using immersion oil or a disinfectant liquid and by pressing the glass disc of the scope on the skin, details of epidermis and the junction zone become visible. Hereby it is possible to study the pigment pattern of the lesions, especially the pigment network which is the main object of dermatoscopic investigation.
