Abstract:Aims:The aim was to study the trichoscopy features of selected hair and scalp conditions by two dermoscopic devices with different modes that is, polarized (noncontact) and nonpolarized (contact) mode.Materials And Methods:The present study included 11 clinical varieties of cases with total 112 patients, attending Sir Takhtasinh Hospital, Bhavnagar in the last 2 years. The clinical history was recorded for each case, and images were taken in both the Heine and DermLite II pro dermatoscope. We used polarized mo… Show more

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).

Trichoscopy (dermoscopy of the hair and scalp) is a technique that improves diagnostic accuracy and follow-up with hair and scalp disorders. Although several studies of trichoscopy have been made in Caucasian and Asian populations, little has been published regarding trichoscopy findings in skin of color, despite the great prevalence of hair diseases in populations with this kind of skin. The aim of this review was to describe the trichoscopic features of normal scalp and of hair disorders in patients with dark skin phototypes. This will help dermatologists to distinguish between unique trichoscopic features of dark skin, and allow them to provide more accurate diagnoses and treatments for these patients.
“…So far, the most common therapeutic monitoring for SD is based on clinical assessment, although the identification of minimal changes may sometimes be difficult. Scalp dermoscopy or trichoscopy, which allows a magnified view of the scalp with image capture/storage facility, is a noninvasive tool for the diagnosis and treatment monitoring that has shown to be useful in some inflammatory scalp disorders [21,22,23]. …”
Purpose: The aim of this study was to assess the efficacy and tolerability of a combination noncorticosteroid, antiinflammatory/antifungal shampoo versus 1% ketoconazole shampoo in the treatment of mild-to-moderate scalp seborrheic dermatitis (SD). Procedures: Twenty patients were randomized to using the combination shampoo (group A, 10 patients) or the 1% ketoconazole shampoo (group B, 10 patients) 3 times a week every other day for 8 weeks. Efficacy was evaluated by measuring the degree of scaling and pruritus by clinical and trichoscopic examination using a 4-point scale. Additionally, a physician global assessment (PGA) was assessed at the end of the study. Results: At 4 weeks, there was a significant reduction of scaling from baseline for both groups, while pruritus showed a significant reduction only for group A. After 8 weeks, there was a significant reduction of scaling and pruritus for both groups. PGA showed a complete response in 90% of the cases in both groups. Conclusions: The results of our study demonstrate that the combination noncorticosteroid, antiinflammatory/antifungal shampoo represents an alternative approach to standard topical treatment for scalp SD. A noncorticosteroid shampoo may be equally safe and effective as ketoconazole shampoo for scalp SD, and trichoscopy provides accurate and reliable quantifiable data to assist in therapeutic monitoring.
