Primary orbital melanoma associated with nevus of Ota

is, needless increases in excised margins. In conclusion, while dermoscopy has a high accuracy for BCC diagnosis and histopathological subtype classification, it had a limited accuracy for lateral margin assessment of superficial, micronodular, infiltrative, morpheaform, and mixed BCC. The presence of superficial fine telangiectasias, shiny white-red structureless areas, and white streaks were predictors of histologic positive margins. When using dermoscopy to delineate tumor margins, one should be aware of its limitations for narrow-excision margins. Further large studies that correlate dermoscopic findings outside the delineated MMS first-stage margins with histologic positive margins are necessary to determine if described dermoscopic BCC features are “camouflaged” by photodamaged skin or if certain BCCs are truly “invisible” to dermoscopy.
