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) Reed nevus, melanoma, recurrent nevus. Dermoscopy of plantar warts typically reveals multiple prominent hemorrhages within a well-defined, yellowish papilliform surface, in which skin lines are interrupted. This pattern is particularly useful for their discrimination from callus, which lacks blood spots, but instead displays central reddish to bluish structureless pigmentation. 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.
The dermoscopic pattern of genital warts was initially described as a mosaic pattern consisting of a white reticular network surrounding central small islands of unaffected mucosal skinThis glossary term has not yet been described.. More recently, the authors of a study including a large number of patients identified 4 different dermoscopic patterns, which may also coexist in a single wart: unspecific, fingerlike, mosaic and knoblike pattern. 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 flat melanocytic lesions inflammatory diseases Bowen disease were detected.branched vesselsarborizing vessels Bright red sharply in focus large or thick diameter vessels dividing into smaller vessels BCC (‘red corona’), compose the stereotypic dermoscopic pattern of the disease (Fig 9c).
