The hand-held dermatoscope improves the clinical evaluation of port-wine stains

Dermatoscopy: Alternative uses in daily clinical practice

“…84 With the use of dermatoscopy, port-wine stains have been classified as superficial or papillary (type 1), consisting of roundish, red structures, and deeper or reticular (type 2), represented by prominent, red linear structures, forming irregular networks in the horizontal subepidermal plexus. 84,85 Another possible finding includes a gray whitish veil, due to the deep dermal distribution of the lesion. 86,87 Two more patterns have been observed.…”

Dermoscopic Features of Plaque Psoriasis and Lichen Planus: New Observations

“…The lesions were evaluated with the handheld dermoscope (Delta 10; Heine Optotechnik, Germany), with a fixed magnification ×10, and photographed with the Dermaphot photographic equipment (Heine Optotechnik) after being covered with olive oil. In a first phase, we searched in both diseases for all those features described in classic capillaroscopy [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17], pigmented tumors [18, 19, 20, 21, 22, 23]and also in our own reported experience [24, 25, 26, 27]. In addition, some new structures were found and described.…”

Dermoscopy in General Dermatology

“…From 1955 to January 2005, we found 61 dermoscopy articles reporting a variety of different indications in the context of NPSD [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61]. Preferentially we did not include dermoscopy articles in which the differential diagnosis to pigmented skin tumors was discussed.…”

“…It has been postulated that the venous plexus of PWS revealing dotted and/or globular patterns without a gray-whitish veil on dermoscopy is located superficially in the upper dermis and thus predicting a good response to laser treatment. By contrast, the presence of a gray-whitish veil indicates the location of the venous malformation in the deeper parts of the dermis and treatment success should be considered unsure [26, 27]. Further indications of dermoscopy in the monitoring of treatment are reported in patients with scabies [19], vitiligo [28], hair loss [29], as well as for the non-surgical topical and systemic treatment of basal cell carcinoma [30] and Kaposi sarcoma [31, 32], respectively.…”

“…In patients with port-wine stains (PWS), the pretreatment dermoscopic evaluation enables clinicians to estimate and predict the response to laser treatment [26, 27]. It has been postulated that the venous plexus of PWS revealing dotted and/or globular patterns without a gray-whitish veil on dermoscopy is located superficially in the upper dermis and thus predicting a good response to laser treatment.…”
