“…In our study, dermoscopy enhanced the demonstration of Wikham's striae which were not visible with the naked eye. 7,9 After observing different dermoscopic findings in psoriasis and lichen planus we are able to diagnose both the diseases dermoscopically with consistent findings without the need for invasive skin biopsy. Our observations clearly showed that simultaneous evaluation of both vascular and non-vascular findings improves surface microscopy of inflammatory dermatosis.…”

“…Our observations clearly showed that simultaneous evaluation of both vascular and non-vascular findings improves surface microscopy of inflammatory dermatosis. [3][4][5][6][7][8][9] In conclusion, dermoscopy is a valuable tool for improving the accuracy of differentiation of non-pigmented scaly lesions. It provides a quick, simple and non-invasive aid.…”

“…Given that Plaque Psoriasis and other inflammatory skin diseases may sometimes be difficult to differentiate clinically, a more detailed determination of specific dermoscopic patterns of inflammatory skin diseases could be a valuable addition for the clinical assessment. [5][6][7][8][9] Purpose of this study is to analyse various dermoscopic patterns of psoriasis and lichen planus. With the acceptance of standardized dermoscopic criteria worldwide as diagnostic test would obviate the need for invasive histopathology.…”

BACKGROUNDDermoscope is non-invasive diagnostic tool, which allows rapid and magnified in-vivo observation of the skin and helps in visualization of morphologic features invisible to naked eye. Dermoscopy is useful in evaluating pigmented lesions, but it can also be used in evaluating the inflammatory skin disorders but little is currently known about their dermoscopic features. Dermoscopy of Psoriasis shows red globules, red lines, red dots, glomeruli-like vessels and light red background. Dermoscopy of Lichen planus shows Wickham's striae, central yellow brown area, grey blue dots, comedo-like opening, corn pearls. AIMSTo determine and compare dermoscopic patterns of Psoriasis and Lichen Planus and correlate the dermatoscopic images with histopathology of Psoriasis and Lichen planus in clinically difficult cases and compare the findings seen in our study with previous studies. MATERIALS AND METHODSA cross-sectional comparative study, during course of 2 years, total of 80 cases in which 40 patients each of Psoriasis and Lichen planus were included. Digital dermoscopic images of lesions were obtained with Hanse microscope, after lesions were covered with olive oil. All dermoscopic findings of both psoriasis and lichen planus were observed, captured and data was analysed statistically. In clinically difficult and atypical cases, histopathology was done and correlated with dermoscopy. STATISTICAL ANALYSISFor all the statistical analysis SPSS statistical software, version 17.0 for windows (SPSS Inc. Chicago, IL, USA) was used. ChiSquare (χ 2 ) test was done for statistical significance. In all instances, a "p" value of 0.05 was considered significant. Charts were prepared with Microsoft Excel 2010 version. RESULTSOn dermoscopy there is statistical significance at 5% confidence interval of red globules (p=0.001, χ 2 =37.143), Wickham's striae (p=0.001, χ 2 =34.286), grey blue dots (p=0.000, χ 2 =13.067) and glomeruli like vessels (p=0.003, χ 2 =8.538) in comparison between psoriasis and lichen planus. Dermoscopic findings of psoriasis were predominantly vascular while those of lichen planus were predominantly non-vascular. CONCLUSIONClinical use of dermoscopy in inflammatory dermatosis improves diagnostic ability and improves fundamental aspects of daily practice such as improvement of morphologic knowledge for visual tele-dermatology and in addition plays a psychological placebo effect on patients suffering from common inflammatory dermatosis.

“…Comedo-like structures filled with corneal content may also appear [18] . Lichen planus can be dermoscopically diagnosed by revealing the pathognomonic Wickham striae [8,19] . Besides the diagnostic role of dermoscopy, useful information for the monitoring of pigmented lichen planus can be obtained.…”

Abstract:Over the last few years, dermoscopy has been shown to be an effective diagnostic tool in assisting the noninvasive diagnosis not only of skin tumors but also of various general dermatological disorders. The use of dermoscopy has offered a new morphological dimension supporting the diagnosis and clinical follow-up of several dermatological conditions. Within the last years, dermoscopy is gaining ground in general dermatology as well. Among the large spectrum of skin infections, specific dermoscopic patterns have been described for common skin infections such as viral warts, molluscum contagiosum, scabies, and pediculosis, as well as for tinea nigra, tungiasis, and cutaneous larva migrans. Also, common skin disorders such as psoriasis, pityriasis rosea or lichen planus show characteristic dermoscopic patterns. The aim of this article is to provide an overview of the use of dermoscopy in general dermatology by analyzing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical characteristics.
