Dermoscopy of small melanomas: just miniaturized dermoscopy?

Abstract

Micromelanomas are not a rarity. However, the clinician should be aware of the fact that the majority of them lack most of the dermoscopic features presented by larger lesions.

Dermoscopy of periungual pigmented Bowen's disease: its usefulness in differentiation from malignant melanoma

“…On the other hand, blue-whitish veil corresponds to epidermal acanthosis with the compact orthokeratosis typical of invasive MM. 6 Phan et al 7 reported the sensitivity of the blue-whitish veil in acral lentiginous melanoma of the palms and soles is 36%. Glomerular vessels are known to be a specific characteristic of Bowen's disease (specificity: 80%) 8 ; however, we were unable to confirm the presence of any glomerular vessels in our cases.…”

An integrated clinical‐dermoscopic risk scoring system for the differentiation between early melanoma and atypical nevi: the iDScore

“…[1][2][3] Allowing the visualization of a series of not otherwise visible cutaneous structures, dermoscopic examination is able to significantly improve the clinical diagnosis compared with naked eye. [1][2][3][4][5][6][7][8] Several algorithms (i.e. [1][2][3][4][5][6][7][8] Several algorithms (i.e.…”

“…[1][2][3][4][5][6][7][8] Several algorithms (i.e. [7][8][9][10][11][12][13][14][15][16] However, the diagnostic accuracy of these algorithms appeared to be unsatisfactory when they were applied to difficult-to-diagnose PSL (i.e. [7][8][9][10][11][12][13][14][15][16] However, the diagnostic accuracy of these algorithms appeared to be unsatisfactory when they were applied to difficult-to-diagnose PSL (i.e.…”

“…ABCD rule, 10 Menzies method, 11 7-point checklist, 12 3-point checklist, 13 CASH algorithm, 14 7-point checklist revisited 15 and chaos and clues 16 ) were developed aimed to provide dermatologists a standardized and more objective dermoscopic approach to PSL. 7,[17][18][19][20] Moreover, these dermoscopic algorithms do not take into consideration neither clinical parameter nor patient personal data which are of pivotal importance in orienting the clinical diagnosis in front of difficult PSL, where the morphologic appearance is sufficient. early melanoma -MMvs.…”

“…[1][2][3][4][5][6] Nevertheless, dermoscopy is a morphologic and subjective method, therefore affected by some limits, such as low reproducibility, poor concordance between dermoscopists and stressors-dependency. [1][2][3][4][5][6][7][8] Several algorithms (i.e. ABCD rule, 10 Menzies method, 11 7-point checklist, 12 3-point checklist, 13 CASH algorithm, 14 7-point checklist revisited 15 and chaos and clues 16 ) were developed aimed to provide dermatologists a standardized and more objective dermoscopic approach to PSL.…”
