Dermoscopic patterns seen in mucosal lesions

(A) Dermoscopic patterns of lines, pseudopods, circles, clods, and dots can be seen in mucosal lesions. However, a single dot or a single line does not constitute a pattern.
(B) The term pattern is defined as a collection of multiple elements of the same type that cover a considerable part of the lesion: lines (1), pseudopods (1), circles (2), clods (3), dots (4), and structureless areas (5).
