Description This chapter describes the 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. of HPV infections

Common wartsThis glossary term has not yet been described. (verruca vulgaris) dermoscopically display multiple densely packed papillae, each containing a central red dotSee [[Glossary:Dots|Dots]] or loop, which is surrounded by a whitish halo. Hemorrhages represent a possible additional feature, appearing as irregularly distributed, small, red to black tiny dots or streakslines radial (always at periphery) streaks Reed nevus melanoma recurrent nevus.[1][2][3] DermoscopyThe examination of [skin lesions] with a 'dermatoscope'.

This pattern is particularly useful for their discrimination from callus, which lacks blood spots, but instead displays central reddish to bluish structureless pigmentation.[4][5][6] Dermoscopy of plane warts typically reveals regularly distributed, tiny, red dots on a light brown to yellow background. These findings allow differentiation from acne or folliculitis, which display a central white to yellow pore corresponding to the comedo or pus within the hair follicle opening.[1]

The dermoscopic pattern of genital warts was initially described as a mosaic pattern consisting of a white reticular networkThis glossary term has not yet been described. surrounding central small islands of unaffected mucosal skinThis glossary term has not yet been described..[1] More recently, the authors of a study including a large number of patients identified 4 different dermoscopic patternsThis glossary term has not yet been described., which may also coexist in a single wart: unspecific, fingerlike, mosaic and knoblike pattern.[7] Concerning vesselsThis glossary term has not yet been described. morphologyThis glossary term has not yet been described., glomerular, hairpin/dotted, and glomerular/dotted vesselstiny pinpoint vessels were detected.
