Abstract
Chronic nodular prurigo (CNP) is a chronic dermatological disease characterized by the presence of chronic pruritus and pruritic nodular lesions. The aim of this study was to reach consensus among a group of experts based on a non-systematic literature review and an algorithm for the clinical diagnosis of CNP. The resulting algorithm is structured in 3 blocks: 1) early identification of the patient with a possible diagnosis of CNP; 2) diagnosis and assessment of CNP; and 3) categorization of CNP (identification of the underlying causes or associated comorbidities). We believe that this clinical algorithm can facilitate the correct diagnosis of patients with CNP. Additionally, it raises awareness on the need for a multidisciplinary approach and specific treatment of CNP, steps of paramount importance to make better therapeutic decisions.

Abstract
INTRODUCTION Over the few last decades, dermoscopy has become an invaluable and popular imaging technique that complements the diagnostic armamentarium of dermatologists, being employed for both tumors and inflammatory diseases. Whereas distinction between neoplastic and inflammatory lesions is often straightforward based on clinical data, there are some scenarios that may be troublesome, e.g., solitary inflammatory lesions or tumors superimposed to a widespread inflammatory condition that may share macroscopic morphological findings. EVIDENCE ACQUISITION We reviewed the literature to identify dermoscopic clues to support the differential diagnosis of clinically similar inflammatory and neoplastic skin lesions, also providing the histological background of such dermoscopic points of differentiation. EVIDENCE SYNTHESIS Dermoscopic differentiating features were identified for 12 relatively common challenging scenarios, including Bowen's disease and basal cell carcinoma vs. psoriasis and dermatitis, erythroplasia of Queyrat vs. inflammatory balanitis, mammary and extramammary Paget's disease vs. inflammatory mimickers, actinic keratoses vs. discoid lupus erythematosus, squamous cell carcinoma vs. hypertrophic lichen planus and lichen simplex chronicus, actinic cheilitis vs. inflammatory cheilitis, keratoacanthomas vs. prurigo nodularis, nodular lymphomas vs. pseudolymphomas and inflammatory mimickers, mycosis fungoides vs. parapsoriasis and inflammatory mimickers, angiosarcoma vs granuloma faciale, and Kaposi sarcoma vs pseudo-Kaposi. CONCLUSIONS Dermoscopy may be of aid in differentiating clinically similar inflammatory and neoplastic skin lesions.

Abstract
Introduction Spongiosis is defined as intercellular edema and vesicles in the epidermis. Histopathology is the gold standard for the diagnosis of spongiotic disorders. Clinical diagnosis of eczema is sometimes unclear and confused with other dermatoses; histopathology often shows spongiotic tissue reaction patterns; such conditions are called spongiotic disorders. It is challenging for a dermatologist to make the correct diagnosis noninvasively with a dermoscope and thus we have taken up the study to correlate the dermoscopic and histopathological findings in spongiotic disorders to set dermoscopic criteria for the diagnosis. Objective To study the dermoscopic features of spongiotic disorders and correlate clinical, dermoscopic, and histopathological findings. Materials and Methods Two hundred fifty two patients, with history and clinical presentation suggesting eczema were enrolled. They were classified as Acute (<6 weeks), Subacute (6 weeks to 3 months), and Chronic (>3 months) eczemas based on duration. Dermoscopy and skin biopsy were performed on representative lesions. Data were compiled and statistically analyzed using frequency distribution and Chi-square test. Results We correlated the diagnosis based on acute, subacute, and chronic with three modalities, clinical examination, dermoscopy, and histopathology. On clinical examination, acute (27.4%), subacute (42.9%), and chronic (29.7%) dermatitis. On dermoscopy, acute (28.5%), subacute (40.4%), and chronic (31.1%) dermatitis. On histopathology, acute (29.5%), subacute (44.2%), and chronic (26.3%) spongiosis. A positive correlation of 99%, 96.2%, and 95% was observed on dermoscopy and histopathology, in acute, subacute, and chronic eczemas, respectively. Dermoscopy of acute eczemas showed linear vessels (100%) and red background (100%). White-Clods (98.9%) and excoriation marks (70.1%). Dermoscopy of subacute eczemas showed white scales (99.1%), irregular pigment network (98.3%), vascular changes with irregular dots (97.4%), a brown-white background (93.1%), and black/brown/grey dots (91.4%). Dermoscopy of chronic eczema showed brown-white background (100%), irregular pigment network (100%), and black/brown/grey blotches (100%). Conclusion Definitive dermoscopic patterns are observed consistently with spongiotic diseases and these can be used additionally to set dermoscopic criteria and confirm the diagnosis. Also, dermoscopic findings are well correlated with the already established histopathological features.

Abstract
In this study, dermoscopy was applied to determine the site of skin biopsy in cases of palmoplantar pustulosis (PPP) with invisible tiny pustules or vesicles. Fifty-two clinically diagnosed PPP patients (11 men and 41 women) were observed by a dermoscope and underwent skin biopsy. Nineteen patients had visible pustules, whereas 33 had no visible pustules. Pustules were detected by a dermoscope on palmoplantar lesions in 17 of the 33 PPP patients. In contrast, 16 patients showed no presence of pustules or vesicles observed by a dermoscope. In this group, biopsy specimens were taken from scaly lesions. Out of the 16 patients, 10 histologically showed pustules in the epidermis. We finally detected pustules for 46 patients among 52 who were clinically diagnosed with PPP. As a result, we detected pustules in PPP for 19 patients on "inspection", and 36 patients on "inspection and dermoscopy", and 46 patients on "inspection, dermoscopy, and biopsy". Dermoscopy is significantly useful comparing the detection rate (inspection, 0.41; inspection and dermoscopy, 0.78; p = 0.0003; using χ2 -test). In addition, we also should learn from the results that the detection rate goes down to 0.78 without a biopsy. Thus, dermoscopy is certainly a useful tool for invisible pustules and also undetectable pustules to detect pustules in PPP. Moreover, we objectively showed that "inspection, dermoscopy, and biopsy" are the best way to make a PPP diagnosis.

Abstract
In addition to its use in pigmented and nonpigmented skin tumors, dermoscopy is gaining appreciation in assisting the diagnosis of nonneoplastic diseases, especially inflammatory dermatoses (inflammoscopy). In this field, dermoscopic examination should be considered as the second step of a "2-step procedure," always preceded by the establishment of a differential diagnosis on the basis of clinical examination. In this paper, we sought to provide an up-to-date overview on the use of dermoscopy in common inflammatory dermatoses based on the available literature data. For practical purposes, the analyzed dermatoses are grouped according to the clinical presentation pattern, in line with the 2-step procedure principle: erythematous-desquamative and papulosquamous dermatoses, papulokeratotic dermatoses, erythematous facial dermatoses, sclero-atrophic dermatoses, and miscellaneous.

Abstract
BACKGROUND Over the last few years, several articles on dermoscopy of non-neoplastic dermatoses have been published, yet there is poor consistency in the terminology among different studies. OBJECTIVES We aimed to standardize the dermoscopic terminology and identify basic parameters to evaluate in non-neoplastic dermatoses through an expert consensus. METHODS The modified Delphi method was followed, with two phases: (i) identification of a list of possible items based on a systematic literature review and (ii) selection of parameters by a panel of experts through a three-step iterative procedure (blinded e-mail interaction in rounds 1 and 3 and a face-to-face meeting in round 2). Initial panellists were recruited via e-mail from all over the world based on their expertise on dermoscopy of non-neoplastic dermatoses. RESULTS Twenty-four international experts took part in all rounds of the consensus and 13 further international participants were also involved in round 2. Five standardized basic parameters were identified: (i) vessels (including morphology and distribution); (ii) scales (including colour and distribution); (iii) follicular findings; (iv) 'other structures' (including colour and morphology); and (v) 'specific clues'. For each of them, possible variables were selected, with a total of 31 different subitems reaching agreement at the end of the consensus (all of the 29 proposed initially plus two more added in the course of the consensus procedure). CONCLUSIONS This expert consensus provides a set of standardized basic dermoscopic parameters to follow when evaluating inflammatory, infiltrative and infectious dermatoses. This tool, if adopted by clinicians and researchers in this field, is likely to enhance the reproducibility and comparability of existing and future research findings and uniformly expand the universal knowledge on dermoscopy in general dermatology. What's already known about this topic? Over the last few years, several papers have been published attempting to describe the dermoscopic features of non-neoplastic dermatoses, yet there is poor consistency in the terminology among different studies. What does this study add? The present expert consensus provides a set of standardized basic dermoscopic parameters to follow when evaluating inflammatory, infiltrative and infectious dermatoses. This consensus should enhance the reproducibility and comparability of existing and future research findings and uniformly expand the universal knowledge on dermoscopy in general dermatology.

Abstract
Prurigo nodualris (PN) is a chronic condition with highly pruritic, hyperkeratotic papules or nodules arising in the setting of chronic pruritus. While PN may serve as a phenotypic presentation of several underlying conditions such as atopic dermatitis, chronic kidney disease-related pruritus, and neurological diseases, it represents a distinct clinical entity that may persist despite the removal of the underlying cause, if one is identified. Neuronal proliferation, eosinophils, mast cells, and small-fiber neuropathy play a role in the production of pruritus in PN, although the exact mechanism has not yet been established. Identifying an underlying cause, if present, is essential to prevent recurrence of PN. Due to often present comorbidities, treatment is typically multimodal with utilization of topical and systemic therapies. We performed a PubMed/MEDLINE search for PN and present a review of recent developments in the treatment of PN. Treatment typically relies on the use of topical or intralesional steroids, though more severe or recalcitrant cases often necessitate the use of phototherapy or systemic immunosuppressives. Thalidomide and lenalidomide can both be used in severe cases; however, their toxicity profile makes them less favorable. Opioid receptor antagonists and neurokinin-1 receptor antagonists represent two novel families of therapeutic agents which may effectively treat PN with a lower toxicity profile than thalidomide or lenalidomide.

Abstract
Background: A dermoscope is an office tool used in the diagnosis of various disorders. At present, studies on hypertrophic lichen planus (HLP) and prurigo nodularis (PN) are limited. Aims and Objectives: The aim of this study was to compare the dermoscopic features of HLP and PN and to determine the role of dermoscopy in the differential diagnosis of both the conditions. Materials and Methods: A cross-sectional study was undertaken. After clinical assessment and relevant investigations, dermoscopy was performed using DermLite DL3 dermoscope (×10) followed by histopathology. Dermoscopic findings in cases of HLP and PN were evaluated. Results: Thirty patients each with HLP and PN were included in the study. On dermoscopy, peripheral striations were the most common findings in both the conditions. Statistically significant features on intergroup comparison included blue–gray globules (P<0.001), comedo-like openings (P<0.001), and follicular plugging (P<0.001) in HLP and pearly white areas with white starburst pattern (P=0.028), red dots and globules (P<0.001), glomerular vessels (P=0.003), crusting (P=0.002), and erosions (P<0.001) in PN. Conclusion: Dermoscopy is useful in differentiating HLP and PN. Blue-gray globules, comedo-like openings, and follicular plugging were specific for HLP. Pearly white areas with white starburst pattern and red dots and globules were the specific findings in PN.

Abstract
Background Pityriasis lichenoides is an uncommon skin disease that presents in three different forms: pityriasis lichenoides et varioliformis acuta (PLEVA), pityriasis lichenoides chronica (PLC) and febrile ulceronecrotic-Mucha-Habermann disease. These represent a spectrum of a disease. PLEVA presents as skin eruption of multiple, small, red papules that develop into polymorphic lesions with periods of varying remissions, as well as possible sequels of hyper/hypopigmentation and varicella-like scars. Diagnosis of this condition is mainly clinical, and sometimes clinical differentiation from other conditions may be a difficult task that often requires histological analysis. In this study, PLEVA lesions were examined by dermoscopy, and the significance of specific dermoscopic findings was investigated in order to facilitate their differentiation from other inflammatory conditions. Objectives To evaluate dermoscopic patterns in PLEVA and to correlate these patterns with histopathology. Materials and methods The study was conducted at S. Nijalingappa Medical College, Bagalkot. It was an observational case series study and patients were selected randomly. Ethical clearance and informed consent were obtained. PLEVA lesions in early and late phases were evaluated. A manual DermLite 3 (3Gen, San Juan Capistrano, CA) dermoscope attached to a Sony (Cyber Shot DSC-W800, Sony Electronics Inc., San Diego, California, USA, digital, 14 mega pixels) camera was employed. Histopathology was done to confirm the diagnosis. Data was collected and analyzed. Results were statistically described in terms of frequencies and types of dermoscopic patterns. Results There was a total of 14 patients; 8 males and 6 females. Mean age of patients was 19 years. Mean duration of disease was 7 months. Dermoscopy in early-phase lesions revealed amorphous brownish areas around the hair follicles, dotted vessels, and scaling. Dermoscopy in late-phase lesions showed whitish-structureless areas and central white crust within whitish-structureless rim with scale, focal bluish-grayish areas or centrifugal strands irregularly distributed along the periphery and yellow structures. Red dots and hemorrhage were seen at the center and glomerular vessels at the periphery. Conclusion PLEVA demonstrates specific dermoscopic patterns that correlate well with histologic changes. New dermoscopic findings are described. Thus, dermoscopy is a good diagnostic tool in the clinical diagnosis of PLEVA.

Abstract
Over the last few years, dermoscopy has been shown to be a useful tool in assisting the noninvasive diagnosis of various general dermatological disorders. In this article, we sought to provide an up-to-date practical overview on the use of dermoscopy in general dermatology by analysing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical presentation, i.e. dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides and subacute cutaneous lupus erythematosus), papulosquamous/papulokeratotic dermatoses (lichen planus, pityriasis rosea, papulosquamous sarcoidosis, guttate psoriasis, pityriasis lichenoides chronica, classical pityriasis rubra pilaris, porokeratosis, lymphomatoid papulosis, papulosquamous chronic GVHD, parakeratosis variegata, Grover disease, Darier disease and BRAF-inhibitor-induced acantholytic dyskeratosis), facial inflammatory skin diseases (rosacea, seborrheic dermatitis, discoid lupus erythematosus, sarcoidosis, cutaneous leishmaniasis, lupus vulgaris, granuloma faciale and demodicidosis), acquired keratodermas (chronic hand eczema, palmar psoriasis, keratoderma due to mycosis fungoides, keratoderma resulting from pityriasis rubra pilaris, tinea manuum, palmar lichen planus and aquagenic palmar keratoderma), sclero-atrophic dermatoses (necrobiosis lipoidica, morphea and cutaneous lichen sclerosus), hypopigmented macular diseases (extragenital guttate lichen sclerosus, achromic pityriasis versicolor, guttate vitiligo, idiopathic guttate hypomelanosis, progressive macular hypomelanosis and postinflammatory hypopigmentations), hyperpigmented maculopapular diseases (pityriasis versicolor, lichen planus pigmentosus, Gougerot-Carteaud syndrome, Dowling-Degos disease, erythema ab igne, macular amyloidosis, lichen amyloidosus, friction melanosis, terra firma-forme dermatosis, urticaria pigmentosa and telangiectasia macularis eruptiva perstans), itchy papulonodular dermatoses (hypertrophic lichen planus, prurigo nodularis, nodular scabies and acquired perforating dermatosis), erythrodermas (due to psoriasis, atopic dermatitis, mycosis fungoides, pityriasis rubra pilaris and scabies), noninfectious balanitis (Zoon's plasma cell balanitis, psoriatic balanitis, seborrheic dermatitis and non-specific balanitis) and erythroplasia of Queyrat, inflammatory cicatricial alopecias (scalp discoid lupus erythematosus, lichen planopilaris, frontal fibrosing alopecia and folliculitis decalvans), nonscarring alopecias (alopecia areata, trichotillomania, androgenetic alopecia and telogen effluvium) and scaling disorders of the scalp (tinea capitis, scalp psoriasis, seborrheic dermatitis and pityriasis amiantacea).

Abstract
Background: Hypertrophic lichen planus (HLP) classically involves shin and ankles and is characterized by hyperkeratotic plaques and nodules. Prurigo nodularis (PN) is a chronic neurodermatitis that presents with intensely pruritic nodules. Histopathology of HLP and PN demonstrate epidermal hyperplasia, hypergranulosis, and compact hyperkeratosis. The dermis shows vertically arranged collagen fibers and an increased number of fibroblasts and capillaries in both conditions. Moreover, basal cell degeneration is confined to the tips of rete ridges, and band-like infiltration is conspicuously absent in HLP. Therefore, both conditions mimic each other clinically, which makes diagnosis difficult. Hence, there is a need for a diagnostic technique to differentiate both conditions. Objective: To evaluate dermoscopic patterns in HLP and PN and to study these patterns histopathologically. Materials and methods: The study was conducted at S. Nijalingappa Medical College in Bagalkot. It was an observational case series study. Ethical clearance and informed consent was obtained. A Dermlite 3 dermoscope (3Gen, San Juan Capistrano, CA, USA) attached to a Sony Cyber Shot camera DSC-W800 (Sony Electronics Inc., San Diego, California, USA) was employed. Histopathology was done to confirm the diagnosis. Results: There were 10 patients each with HLP and PN. HLP was seen in 8 males and 2 females. PN was observed in 7 females and 3 males. Dermoscopy of HLP demonstrated pearly white areas and peripheral striations (100%), gray-blue globules (60%), comedo-like openings (30%), red dots (40%), red globules (10%), brownish-black globules (30%), and yellowish structures (90%). In PN, red dots (70%), red globules (60%), and pearly white areas with peripheral striations (100%) were observed under dermoscopy. Conclusion: Both HLP and PN demonstrated specific dermoscopic patterns which can be demonstrated on histopathologic findings. The authors propose that these patterns are hallmarks of each condition. Thus, dermoscopy is a good diagnostic tool in the differentiation of HLP and PN.

Abstract
Type 1 segmental Darier's disease is a blaschkolinear variant of Darier's disease resulting from a postzygotic mosaicism. Since it usually lacks diagnostic clues typical of the generalized form, including positive family history of the disease, nail and mucosal abnormalities, and/or acral involvement, its distinction from other acquired inflammatory blaschkolinear dermatoses may often be quite challenging, thus requiring histopathological examination to reach a definitive diagnosis. We report a case of type 1 segmental Darier's disease with its dermoscopic findings in order to show the usefulness of dermoscopy in assisting the noninvasive identification of this condition.

Abstract
Pruritic folliculitis of pregnancy is a noninfective dermatosis of the gestation period characterized by multiple pruritic follicular papules and/or pustules which is not uncommonly mistaken for other similar skin disorders that may occur during pregnancy. In the present article we describe the usefulness of dermoscopy as a supportive diagnostic tool in a case of pruritic folliculitis of pregnancy. The main (always present) dermoscopic clue consisted of a vellus hair in the centre of each papule/pustule. Moreover, most papules showed a central yellowish-orange hue with some dotted vessels and irregular haemorrhagic spots. The detection of the aforementioned dermoscopic features might help distinguish pruritic folliculitis of pregnancy from its main differential diagnoses, mainly including microbial folliculitis, prurigo lesions, and the papular stage of pruritic urticarial papules and plaques of pregnancy, as they typically show different dermoscopic patterns.

Abstract
Distinguishing Grover's disease from other papular dermatoses is often a troublesome task. According to two relatively recent case reports, dermoscopy may be useful in assisting the diagnosis of such a disorder by showing a peculiar pattern. The aim of this study was to evaluate the dermoscopic features of Grover's disease in a larger series of patients and correlate dermoscopy with histopathological findings. Seven patients with histopathologically confirmed Grover's disease were included in the study, with three of them displaying a Darier-like histology and the remaining four cases having a spongiotic histological pattern. The results of our study suggest that Grover's disease may display different features according to the histological subtype, with a central star-shaped/branched polygonal/roundish-oval brownish area surrounded by a whitish halo being characteristic of the Darier-like histological subtype and whitish scales over a reddish-yellowish background being characteristic of the spongiotic histological subtype.

Abstract
Clinical differentiation between palmar psoriasis and chronic hand eczema may sometimes be a diagnostic challenge; in such cases histopathological analysis helps to differentiate the two conditions. In the present study, palmar psoriasis and chronic hand eczema were investigated using dermoscopy and the significance of specific dermoscopic features was assessed in order to improve their non-invasive differentiation. Ten patients with biopsy-proven palmar psoriasis and 11 patients with biopsy-proven chronic hand eczema were included in the study. We found that the presence of diffuse white scales was significant in palmar psoriasis whereas the presence of yellowish scales, brownish-orange dots/globules and yellowish-orange crusts was significant in chronic hand eczema.
