Serpentine and linear branching of BCC are fairly reliable as is the polymorphous pattern with dot vessels for an amelanotic melanoma. The sheet of coiled vessels found in SCC in situ is also a good marker Dermoscopy of lichen planus usually shows thick white lines on a purplish red background allowing the diagnosis in majority of the cases. Nummular dermatitis shows a patchy distribution of dotted and coiled vessels on an erythematous background without a collarette of scale
Dermatoscopic structures of melanocytic lesions. Melanocytic lesions are made up of three types of structure. Pigment network and/or; Amorphous structureless areas (blotches) and/or; Dots and globules; Benign lesions tend to have only one or two of these structural patterns in a symmetrical distribution.Malignant lesions tend to have areas of network, amorphous structures and scattered. Dermoscopy is useful to distinguish pigmented non- melanocytic lesions from benign and malignant melanocytic lesions. There are specific features that help to distinguish seborrhoeic keratosis from basal cell carcinoma and melanoma .0%, P<.001), and were especially seen in Spitz nevi (77.8% of lesions). In melanoma, linear-irregular, dotted, and polymorphous/atypical vessels were the most frequent vascular structures, whereas milky-red globules/areas were the most predictive ones (77.8%, P = .003)
a Dermoscopy of plane wart revealing tiny dotted (pinpoint) vessels on a light brownish background. b Dermoscopy of verruca vulgaris. The dotted vessels are larger than in plane warts and located in the centre of the papillae (frogspawn). c Dermoscopy of verruca palmo-plantaris typically shows dots and brown to red streaks that correspond to. Dermoscopy in Psoriasis can be very useful - because it displays repetitive features. Dermoscopic features of Psoriasis: Uniformity distributed dotted red vessels which histopathologically corresponds to the dilated capillaries found in the elongated dermal papillae; A light/dull red backgroun Vascular structures in dermoscopy are described in the literature that consist of (i) dotted vessels - red dots with diameter of 0.01-0.02 mm and represent tips of the vertically aligned vessels a, (ii) linear vessels - red lines that may be regular or irregular or helical in shape b, (iii) slightly curved short linear (comma-like. Results: Dermoscopy of vermillion frequently revealed dotted vessels that were found in all patients, while linear vessels without bends or branches were seen in 10 of them (62.5%) Dotted blood vessels in dermoscopy (100%) correlated with capillaries in the papillary dermis (100%) (P=0.615), whereas fading red (yellow) background in dermoscopy (75%) correlated with papillary dermal edema with perivascular infiltrate (83.3%) and focal spongiosis in 100% of examined histopathological PR sections (P=0.615 and 0.064.
Appreciate the densely packed and intensely colored globules. Note brownish-gray background and red-colored artefacts (green arrows) which appear as dotted vessels. (e) Dermoscopy of lichen planus pigmentosus demonstrates cobblestone pattern with bluish-gray (red arrows), brown (yellow arrows), and brownish-gray (green arrows) pigment. Studies on the use of dermoscopy in LS are sparse. Shim et al., concluded that WSA and CLO were statistically significant in LS, whereas fibrotic bands were significant in morphea. Nevertheless, comma shaped vessels, hairpin like vessels and dotted vessels were exclusively seen in LS
Dermoscopy revealed multiple curves of semicircle, U or V mimicking the scales of a fish. This fish scale-like pattern was in favor of a mucosal melanotic macule. Fish scale-like pattern is a new pattern described in mucosal melanotic macules. Dermoscopy of pigmented lesion on mucocutaneous junction and mucous membrane Description: On the left, a brown lesion with by place an irregular (thick network), some grey dots, some blue-white structures, and an excentric skin-coloured structureless area.In this area, there is a polymorphic vascular pattern, with some dotted vessels and some short thin serpentine vessels.On the right, a mirror image of the left: a crescent shaped brown lesion

For plaque psoriasis, the combination of regularly distributed dotted vessels with a light red background and diffuse white scales was reported to be 88.0-percent specific and 84.9-percent sensitive. 6 Another study looking at how to differentiate basal cell carcinoma from psoriasis showed that there was a 99-percent diagnostic probability that. Introduction. Dermoscopy, also known as epiluminescence microscopy, epiluminoscopy or skin surface microscopy, is an important way to visualize subsurface structures in the epidermis and dermis. Part one of this article focused on the evaluation of pigmented lesions, and the second installment below will review the different vessel morphologies. Dermoscopy is a widely used non-invasive technique for diagnosing skin tumors. In melanocytic tumors, e.g., melanoma and basal cell carcinoma (BCC), the effectiveness of dermoscopic examination has been fully established over the past two decades. Moreover, dermoscopy has been used to diagnose non-melanocytic tumors. Here, we review novel findings from recent reports concerning dermoscopy of. Arborizing Vessels on Dermoscopy in Various Skin Diseases Other Than Basal Cell Carcinoma Hyunju Jin, 1, 2 Min-Young Yang, 1, 3 Jeong-Min Kim, 1, 2 Gun-Wook Kim, 1, 3 Hoon-Soo Kim, 1, 3 Hyun-Chang Ko, 1, 2 Byung-Soo Kim, 1, 3, 4 and Moon-Bum Kim 1, 3, 4 1 Department of Dermatology, Pusan National University School of Medicine, Yangsan, Korea.: 2 Department of Dermatology, Pusan National.
usefulness of dermoscopy in accurately determining the features of each condition. Additionally, dermoscopy aids in differentiating between psoriasis and squamous cell carcinoma. In contrast to the dotted vessels seen in psoriasis, squamous cell carcinomas often have peripheral hairpin (glomerular) vessels B The nonpigmented lesion is characterized by dotted vessels distributed throughout the entire lesion with a pearlslike arrangement. Together with whitish halo surrounding the red dots, the dermoscopic aspect favored the diagnosis of a clear-cell acanthoma, which was confi rmed by the histopathologic examination
On dermoscopy CCA is highly characteristic, showing dotted or glomerular vessels arranged in a linear or serpiginous pattern. These linear arrangements usually adopt a reticular distribution, forming what is known as a 'string of pearls' pattern, of which this case is very representative. 2 2 Lyons G, Chamberlain AJ, Kelly JW be difﬁcult. On dermoscopy, speciﬁc dermoscopic patterns have been described for IEC. Classical, non pigmented IEC presents the very typical vascular pattern of glomerular and/or dotted vessels. The vessels are typically grouped in clusters within the lesions. On the surface, multiple scales and micro-erosions are found. Recently, patterns.
A 58-year-old north-Moroccan man presented with an asymptomatic pigmented lesion on the pubis that had increased in size for several years. Clinical examination showed a hyperkeratotic heterogeneous pink-brown poorly demarcated 5 × 7-cm plaque (Fig 1). No regional lymphadenopathy was present. Squamous cell carcinoma and seborrheic keratosis were mentioned as differential diagnoses ined by non-contact dermoscopy. Whitish keratotic plugs and linear vessels in yellowish background are significant dermoscopic features of PRP compared to white diffuse scales and dotted vessels in a light red background in PP. In conclusion, PRP and PP reveal specific distinguishing der-moscopic patterns that may assist in their clinical diagnosi

Dermoscopy The dermoscopic hallmark of Zoon's plasma cell balanitis is the presence of focal/diffuse orange-yellowish structureless areas and/or fairly focussed curved vessels (including serpentine, convoluted and chalice-shaped); other possible ﬁndings include linear irregular blurry vessels and dotted vessels.[7,12,14,15,16 The dermoscopy characteristics of CTCL plaques were assessed in two patients (one own patient and one patient published by Ghahramani et al. ). Both CTCL plaques showed dotted vessels on a dull red background with white scale (Tables1and2). Dotted
CHAPTER 15 Dermoscopy Ashfaq A. Marghoob, Azadeh Esmaeili, Alon Scope Skin cancer, the most common malignancy in the United States, is associated with significant morbidity and mortality. Fortunately, early detection of skin cancer, through visual examination of the entire cutaneous surface, can have a positive impact on patient outcomes Dermoscopy is a noninvasive method that allows the in vivo evaluation of colors and microstructures of the epidermis, the dermoepidermal junction, and the papillary dermis not visible to the naked eye. vascular patterns alone may not be sufficient to diagnose melanoma because hairpin vessels, dotted areas, and even milky-red areas have also. INTRODUCTION An arborizing vessel (AV) is composed of a stem vessel 1 and irregular treelike branching vessels . Among a variety of vascular structures on dermoscopy, this appearance of AV is very characteristic, and is regarded as an important dermoscopic feature of basal cell carcinoma (BCC) Dermoscopy of pigmented poromas. Dermatology. 2010; 221(1):78-83 (ISSN: 1421-9832) Polymorphous vessels were observed in 3 cases, of which 2 showed combinations of dotted vessels and linear-irregular vessels and 1 combinations of hairpin vessels and glomerular vessels. Arborizing vessels were observed in 2 cases The best-studied disease is psoriasis, which dermoscopically always displays dotted vessels with regular distribution and white scales 14-16. Dermoscopy makes differential diagnosis among papulosquamous disorders simpler, permitting clinicians to recognize lichen planus (Wickham striae), eczema (yellow crusts and patchy dotted vessels), and.
(C) In dermoscopy dotted vessels are visible over the entire lesion area (white arrows). Scales and crust are present on the surface. Scales and crust are present on the surface. Figure 10 RCM and histologic imaging of the case in Figure 9 Representative dermoscopy photos were taken, and then features were classified. The authors found... important differences in vessels, scale, and pigment between the two diagnoses. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ Guttate psoriasis almost always showed red dotted vessels arranged uniformly Study Dermoscopy flashcards from Samra Saikal's class online, or in Brainscape's iPhone or Android app. Learn faster with spaced repetition Dotted vessels rarely appear in these cases27-30but dotted or corkscrew vessels may appear where melanoma metastasizes into the skin.31 In clear cell acanthoma (CCA), string-like, dotted vessels appear.32,33They are frequently seen in psoriasis vulgaris, pitriasisrosea and lichen planus. 34 Dotted vessels also occur in superﬁ cial and nodula
For plaque psoriasis, the combination of regularly distributed dotted vessels with a light red background and diffuse white scales was reported to be 88.0-percent specific and 84.9-percent sensitive. 6 Another study looking at how to differentiate basal cell carcinoma from psoriasis showed that there was a 99-percent diagnostic probability that. Comma-like and dotted vessels are seen, with ample space in between the vessels. However, image quality and resolution are low owing to the overlying epidermal features. (c) View under dermoscopy with cross-polarisation. The comma-like and dotted vessels are clearly seen. These vessels appear to be 'jumping'. Diagnosis becomes straightforward

The most common immersion fluids in dermoscopy are synthetic oil, ultrasonographic gel, alcoholic disinfectants or, simply - water. central hypopigmentation and numerous dotted-type vessels Dermoscopy is a fast evolving field with a high number of new publications every year. Initially, the use of dermoscopy was limited to pigmented lesions, but it is used more and • Dotted vessels are tiny red dots that are densely aligned next to each other in an irregular fashion (Figure 5) Under the right conditions, dermoscopy allows us to observe the vascular features of many different types of skin lesions. Davidson's principles and practice of medicine. Consultado el 5 April Physiological Reviews 69 2: Some of the more characteristic associations are the presence of crown vessels in sebaceous hyperplasia, arborizing. Dermoscopy of the finger nodule showed an erythematous area, central ulceration, yellow crust, brown dots, a white structureless area partially surrounding the lesion, and dotted vessels (Figure 2).

The mole presents diffuse network pattern, relatively uniform but a bit atypical in some areas, especially on the upper part of the lesion. B. This is a pure globular pattern, with multiple globules and dots; it is unusual in atypical naevi, it is more commonly found in common melanocytic naevi, especially intradermal and compound • recognise the role of dermoscopy in diagnosing skin lesions • list the alternative uses for dermoscopy in general practice • put into place a systematic checklist to aid in preoperative diagnosis Dotted vessels Spitz naevi or melanoma Comma vessels Compound or Dermal naevi Hairpin vessels Melanoma and Seb Keratosis 15 LSK-12-061 Red. With the limitation of the small number of cases, vascular patterns were the only dermoscopic criteria for 'truly' AM. In the 10 cases of 'truly' AM, we found milky-red areas in more than half of the cases (six of 10), dotted vessels in four, hairpin vessels in two, linear irregular vessels in two, dotted and linear irregular vessels in two
The researchers found that dotted vessels in a regular arrangement over a light red background and white scales were highly predictive of the diagnosis of PP. Dermatitis more frequently showed. The most common dermoscopy findings seen were brown globules (96.2%), red diffuse areas (92.4%), vessels (87.1%), white structureless areas (86.4%), and hypertrichosis (80.3%). Red diffuse areas, vessels, brown globules, white structureless areas, and white hair were observed in a statistically higher proportion of cases dermoscopically Dermoscopy revealed dotted vessels and reddish globules, irregularly distributed and surrounded by pinkish white structures. Mucinous carcinoma is characterised by eccrine sweat gland differentiation and represents a low‐grade malignant tumour with the potential of local recurrence. Dermoscopy of mucinous carcinoma has been reported to mirror. Fine white scales were present in 18.8% of the MF lesions. In addition, purpuric dots were identified in 3 of 32 cases (9.4%). 2 Mycosis fungoides: dermoscopy reveals fine short linear vessels, dotted vessels and orange‐yellow patchy areas Dermoscopy shows a central homogeneous rosy-white area, surrounded by thin dark linear concentric structures with several dotted vessels within. In this study, white structureless areas were arranged as if they were running like tree branches. Dotted and linear vessels were noted . White areas correspond to fibrous tissue in the dermis
Kibar Ozturk et al., Dermoscopy of mycosis fungoides 175 in the latest years, some dermoscopic studies have been performed [6-12], in particular for early-stage MF [7, while dotted vessels (p=0.0001), diffuse lamellar white scales (p<0.00001) and dotted and globular vessels (p=0.0001) were common in patients with PP (Tabl Existing studies have used a combination of traditional immersion dermoscopy and polarized light dermoscopy. This is the first study, to our knowledge, to strictly use digital polarized light dermoscopy for the evaluation of clinically nonpigmented, biopsy-proven dermal nevi
Dermoscopy from the alar grooves of healthy adults frequently displays mild to moderate erythema, brown globules and clods, out-of-focus linear and arborizing vessels and telangiectasias, minimal white scaling and the dermoscopic features were a little surprising, e.g., absence of dotted vessels in a patchy distribution typical of facial. dermoscopy.
