Diagnostic criteria for erosive lichen planus affecting the vulva: an international electronic‐Delphi consensus exercise
The British journal of dermatology, 2013Co-Authors: R.c. Simpson, Kim S Thomas, Paul Leighton, Ruth MurphyAbstract:Background: There is no defined set of criteria for diagnosing erosive lichen planus affecting the vulva (ELPV) and there is geographical variation in management. Objectives: To reach consensus on clinicopathological diagnostic criteria for ELPV. Methods: This was a three-stage international electronic-Delphi exercise with a subsequent formal feedback process. In the first two rounds participants were asked to rate the importance of a list of clinicopathological criteria. Responses from round 1 were summarized and presented in round 2, along with additional criteria suggested by participants. In round 3, participants were asked to rate the items that had reached consensus as ‘essential’ or ‘supportive’ features in diagnosing ELPV. Consensus was defined as being reached if 75% of participants agreed on the importance of an item. Results: A total of 73 experts representing dermatology, gynaecology, histopathology and genitourinary medicine participated; 69 (95%) completed all three rounds. Consensus was achieved for the following ‘supportive’ diagnostic criteria: (i) well-demarcated erosions/erythematous areas at the vaginal introitus; (ii) presence of a hyperkeratotic border to lesions and/or Wickham Striae in surrounding skin; (iii) symptoms of pain/burning; (iv) scarring/loss of normal architecture; (v) presence of vaginal inflammation; (vi) involvement of other mucosal surfaces; (vii) presence of a well-defined inflammatory band involving the dermoepidermo junction; (viii) presence of an inflammatory band consisting predominantly of lymphocytes; and (ix) signs of basal layer degeneration. It was suggested that at least three supportive features should be present to make a diagnosis of ELPV, although this number is subject to further discussion. Conclusions: This study has identified a diagnostic dataset for ELPV that can be adopted into clinical practice and clinical trials.

accuracy of dermoscopic criteria for the diagnosis of psoriasis dermatitis lichen planus and pityriasis rosea
British Journal of Dermatology, 2012Co-Authors: Aimilios Lallas, Athanassios Kyrgidis, T Tzellos, Z Apalla, E Karakyriou, Athanasios Karatolias, I Lefaki, Eleni Sotiriou, D Ioannides, Giuseppe ArgenzianoAbstract:Summary Background Dermoscopy is useful in evaluating skin tumours, but its applicability extends also to the field of inflammatory skin disorders. Plaque psoriasis (PP), dermatitis, lichen planus (LP) and pityriasis rosea (PR) are common inflammatory skin diseases, but little is currently known about their dermoscopic features. Objectives To determine and compare the dermoscopic patterns associated with PP, dermatitis, LP and PR and to assess the validity of certain dermoscopic criteria in the diagnosis of PP. Methods Patients with PP, dermatitis, LP and PR were prospectively enrolled. The single most recently developed lesion was examined dermoscopically and histopathologically. Variables included vascular morphology, vascular arrangement, background colour, scale colour, scale distribution and presence of Wickham Striae. Univariate and adjusted odds ratios were calculated. Discriminant functions were used to plot receiver-operator characteristic curves. Results Eighty-three patients with PP and 86 patients with either dermatitis, LP or PR were included in the study. Dotted vessels in a regular arrangement over a light red background and white scales were highly predictive for the diagnosis of PP, whereas dermatitis more commonly showed yellow scales and dotted vessels in a patchy arrangement. PR was characterized by yellowish background, dotted vessels and peripheral scales; whitish lines (Wickham Striae) were seen exclusively in LP. Conclusions PP, LP, PR and dermatitis show specific dermoscopic patterns that may aid their clinical diagnosis. Certain combinations of dermoscopic features can reliably predict the diagnosis of PP.

Dermoscopy for Discriminating Between Lichenoid Sarcoidosis and Lichen Planus
Archives of Dermatology, 2011Co-Authors: Francisco Vázquez-lópez, Laura Palacios-garcia, Santiago Gómez-díez, Giuseppe ArgenzianoAbstract:T HE LESIONS SHOWN WERE LOCATED ON the forearm of a 47-year-old man (Figure 1A), the forearm of a 51-yearold man (Figure 1B), and the trunk of a 55-year-old woman (Figure 1C), all of them presenting with a lichenoid rash. Dermoscopy revealed 2 differential patterns in these lesions: (1) reticular, white Wickham Striae (WS) (Figure 2A) in the papules shown in Figure 1A and (2) round to oval, yellowbrown, homogeneous patches (YPs) (Figure 2B and C) and absence of WS in the lesions shown in Figure 1B and C. A histopathologic diagnosis of lichen planus (LP) was made in 1 patient (Figure 1A, inset), and lichenoid sarcoidosis was diagnosed in the other 2 patients (Figure 1B and C, insets). Lichenoid sarcoidosis represents 1% to 2% of cutaneous sarcoidosis cases and mimics LP. The examples illustrated herein show that dermoscopy may be useful for discriminating between the lesions of LP and those of lichenoid sarcoidosis. The absence of WS and the presence of YPs should prompt clinicians to perform a biopsy to rule out a granulomatous skin disease in clinically lichenoid lesions. Dermoscopy and diascopy of sarcoidosis lesions reveal individual yellow nodules (“grains of sand”) or a yellow-brown discoloration (“applejelly” sign). Yellow-brown homogeneous patches are not specific for sarcoidosis, but they are indicative of a granulomatous skin disease (sarcoidosis, lupus vulgaris, leishmaniasis). Conversely, dermoscopy of active LP lesions reveals the characteristic WS but not the YPs.
