Pyoderma faciale as a possible form of demodicosis in a subset of patients? New insights from dermoscopic examination
No full textDermoscopy in general dermatology (non‐neoplastic dermatoses): pitfalls and tips
No full textBackground: Dermoscopy is gaining appreciation in the spectrum of non-neoplastic skin conditions, especially papulosquamous and granulomatous dermatoses. However, the use of dermoscopy in such diseases has not yet acquired a standard role in daily practice due to the lack of a structured approach as well as possible pitfalls limiting its accuracy. Methods: A descriptive analysis of the most common limitations/pitfalls described in the literature regarding dermoscopy of non-neoplastic dermatoses was performed, also providing possible tips to deal with them. Results: The following items were analyzed: “two-step” dermoscopic procedure and basic dermoscopic parameters in non-neoplastic dermatoses, uniform dotted vessels in dermatoses other than psoriasis, pseudo-Wickham striae, yellow sero-crusts in non-eczematous dermatoses, peripheral scaling collarette in conditions other than pityriasis rosea, orange areas in non-granulomatous dermatoses, and dermoscopic variability of Grover disease according to histological subtype. Conclusions: Dermoscopy is candidate to become a relevant part of diagnostic approach to non-neoplastic dermatoses, yet only the use of a systematic/validated methodology and the in-depth knowledge of possible pitfalls may optimize its use in this field
The practical usefulness of dermoscopy in general dermatology
No full textBeside to traditional use, dermoscopy is more and more used in the assessment of other "general" dermatologic conditions, namely scalp and hair disorders (trichoscopy), nails abnormalities (onychoscopy), skin infections and infestations (entomodermoscopy), and cutaneous inflammatory diseases (inflammoscopy). Among the list of new applications of dermoscopy, the study of inflammatory dermatoses is probably the most promising topic in terms of development and usefulness, considering the large number of such disorders and the frequent problems in their differential diagnosis which the dermatologist encounters in own daily clinical practice. In this paper, we report selected relatively common clinical differential diagnosis issues concerning inflammatory dermatoses (and some clinically related noninflammatory conditions), analysing them by a dermoscopic point of view in order to assist their noninvasive resolution according to the available literature data and our personal experience, including papulosquamous dermatoses (guttate psoriasis, pityriasis lichenoides chronica, pityriasis rosea, lichen planus, lymphomatoid papulosis, classic pityriasis rubra pilaris, papulosquamous sarcoidosis, disseminated forms of porokeratosis and papulosquamous chronic GVHD), dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides, subacute cutaneous lupus erythematosus), palmar psoriasis vs. chronic hand eczema, scalp psoriasis vs. seborrheic dermatitis, erythematous-desquamative disorders typically involving the elbows (psoriasis vulgaris, circumscribed juvenile pityriasis rubra pilaris, dermatomyositis/Gottron's sign), itchy papulonodular dermatoses (hypertrophic lichen planus, prurigo nodularis, nodular scabies and acquired perforating dermatosis), common facial inflammatory skin diseases (rosacea, seborrheic dermatitis and demodicidosis), lichen sclerosus vs. morphea, urticaria vs. urticarial vasculitis and common inflammatory cicatricial alopecia (discoid lupus erythematosus, lichen planopilaris and folliculitis decalvans)

Dermatoscopy in life-threatening and severe acute rashes
No full textA prompt recognition of life-threatening and severe acute rashes is of utmost importance to start an appropriate therapy as soon as possible. Consequently, clinicians often must rely only on clinical data to make a diagnosis because some diagnostic procedures may take a relatively long time to be performed (eg, histologic examination, microbiologic tests). In this scenario, dermatoscopy may be useful as an auxiliary tool to support the diagnosis by highlighting subclinical features. We have provided an up-to-date overview on the use of dermatoscopic assessment in life-threatening and severe acute dermatoses, including erythroderma (due to psoriasis, eczema, pityriasis rubra pilaris, mycosis fungoides, and drugs), pustular eruptions (pustular psoriasis and acute generalized exanthematous pustulosis), bullous eruptions (staphylococcal scalded skin syndrome, toxic epidermal necrolysis, and pemphigus vulgaris), hemorrhagic eruptions (necrotizing vasculitis and calciphylaxis), and erythematous eruptions (erythema multiforme major, Sweet syndrome, and DRESS syndrome)

No full textThe diagnosis of prurigo nodularis is mainly clinical, based on its distinctive features. However, in some cases it may be difficult to differentiate it from other nodular dermatoses only on the clinical basis, thus requiring histopathological examination to reach a definitive diagnosis. The aim of this study was to describe for the first time the dermoscopic features of prurigo nodularis and the useful contribution of dermoscopy in the differential diagnosis of such dermatoses. Fourteen patients with histopathologically proven prurigo nodularis were included in the study. The results of our study suggest that the detection of a "white starburst pattern" surrounding brown-reddish/brown-yellowish crust(s), erosion(s) and/or hyperkeratosis/scales is a useful clue to support the clinical diagnosis of prurigo nodularis, distinguishing it from the other main differential diagnoses. © 2015 Japanese Dermatological Association
