Asymmetry in two axes |
In 0, 1 or 2 perpendicular axes; assess not only contour, but
also colors and structures.1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
|
Atypical dots/ globules |
Black, brown, round to oval, various sizes, irregularly
distributed within the lesion.1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
|
Atypical network |
Black, brown or gray network with irregular holes and thick
lines.1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
|
Streaks |
Linear structures of brown to black color, of variable thickness, not
clearly combined with the lines of the network. It is most evident in the
periphery.1515. Soyer HP, Argenziano G, Chimenti S, Ruocco V. Dermoscopy of
pigmented skin lesions. Eur J Dermatol. 2001;11:270-6.
|
Pseudopods |
Bulbous and often kinked projections that are found at the edge of a
lesion, either directly connected to the tumor body or pigmented network.
They can never be seen distributed regularly or symmetrically around the
lesion. When connected directly to the tumor body, they must have an acute
angle to the tumor edge or arise from linear or curvilinear extensions. When
connected to the network, the width of the bulbous ending must be greater
than the width of any part of the surrounding network and at least double
that of its direc- tly connected network projection.1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
|
Blotches |
Black, brown, and/or gray structureless areas with symmetrical
or asymmetrical distribution within the lesion. 1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
|
|
Blue-white veil |
Irregular, structureless area of confluent blue pigmentation
with an overlying white "ground-glass" film. The pigmentation
cannot cover the entire lesion and usually corresponds to a clinically
elevated part of the lesion.1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
|
Structureless area |
Area with absence of structures larger than 10% of the total
lesion. 1616. Stolz W, Semmelmayer U, Johow K, Burgdorf WHC. Principles of
dermatoscopy of pigmented skin lesions. Semin Cutan Med Surg.
2003;22:9-20.
|
Atypical vessels |
Linear-irregular or dotted vessels not clearly seen within regression
structures. 1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
|
Milky red area |
Globules and/or larger areas of fuzzy or unfocused milky-red
color usually corresponding to an elevated part of the lesion. 1414. Argenziano G, Zalaudek I, Corona R, Sera F, Cicale L, Petrillo G, et
al. Vascular structures in skin tumors: a dermoscopy study. Arch Dermatol.
2004;140:1485-9.
|
|
Island |
Well-circumscribed area which shows a uniform dermoscopic
pattern, different from the rest of the pigmen- ted lesion. 1313. Borsari S, Longo C, Ferrari C, Benati E, Bassoli S, Schianchi S, et
al. Dermoscopic island: a new descriptor for thin melanoma. Arch Dermatol.
2010;146:1257-62.
|
|
Peppering |
Foci of multiple blue or gray dots (not globules) often described as
"pepper-like" granules in pattern.1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
|
White like-scar area |
Areas of white distinct irregular extensions (true scarring),
which should not be confused with hypo- or depigmentation due to simple loss
of melanin. 1212. Argenziano G, Soyer HP, Chimenti S, Talamini R, Corona R, Sera F, et
al. Dermoscopy of pigmented skin lesions: results of a consensus meeting via the
Internet. J Am Acad Dermatol. 2003;48:679-93.
