Scalp Diseases

<b><i>Background:</i></b> The common inflammatory scalp diseases, such as psoriasis, seborrheic dermatitis, lichen planopilaris, discoid lupus erythematosus, contact dermatitis, or pemphigus may share similar clinical features. <b><i>Objective:</i></b> To identify and systematically review the available evidence on the accuracy of trichoscopy in inflammatory scalp disorders. <b><i>Methods:</i></b> A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 58 articles were included in the analysis. <b><i>Results:</i></b> The following trichoscopy features were found to show the highest specificity for the respective diseases: in psoriasis: diffuse scaling, simple and twisted red loops, red dots and globules, and glomerular vessels; in seborrheic dermatitis: atypical vessels, thin arborizing vessels, and structureless red areas; in discoid lupus erythematosus: follicular plugs and erythema encircling follicles; in lichen planopilaris: milky red areas or fibrotic patches; in contact dermatitis: twisted red loops; in pemphigus foliaceus: white polygonal structures and serpentine vessels; in pemphigus vulgaris: red dots with whitish halo and lace-like vessels; and in dermatomyositis: lake-like vascular structures. <b><i>Limitations:</i></b> Different nomenclature and variability in parameters, which were analyzed in different studies. <b><i>Conclusion:</i></b> This systemic analysis indicates that trichoscopy may be used with high accuracy in the differential diagnosis of inflammatory scalp diseases.

Scalp Diseases

This chapter discusses inflammatory scalp diseases and hair shedding (telogen effluvium and pattern hair loss). Inflammatory diseases of the scalp can affect all epidermal surfaces or focus upon the follicle, with relative sparing of the interfollicular skin. Eczema and psoriasis are examples of the former; other diseases, such as lichen planopilaris or discoid lupus erythematosus, are examples of the latter. Some follicular diseases, such as the family of diseases based on alopecia areata (alopecia areata (small areas of hair loss), alopecia totalis (whole scalp), and alopecia universalis (whole body)), cause barely visible follicular inflammation which results in hair loss but no scarring. Some patients present with hair shedding or change of hair pattern as their primary complaint, with no scalp disease; this is telogen effluvium. Others present with an altered pattern of scalp hair without conspicuous shedding; this is pattern hair loss.

Parietal Area

Introduction. Focal alopecia in the parietal area is one of the types of hair loss that can be found in dermatological practice. Trichoscopy is a non-invasive and easily accessible diagnostic method widely used in scalp disorders.Aim. The aim of this study was to assess the usefulness of trichoscopy in the non-invasive diagnosis of focal hair loss in adult women.Material and Methods. The study included 40 adult women. The study group consisted of 30 patients including 10 patients with alopecia areata (AA), 10 patients with discoid lupus erythematosus (DLE) and 10 with classical form of lichen planopilaris (LPP). The control group consisted of 10 healthy volunteers. Four groups of structures observed in trichoscopic examination were evaluated: hair follicle openings, hair shafts, vessels, perifollicular and interfollicular skin surface. Results. Among patients with AA the most frequently observed trichoscopic structures were: yellow dots in 100% (10/10), broken hairs in 90% (9/10), hairs resembling exclamation marks in 90% (9/10). DLE patients most often presented white / white-pink structureless areas and prominent, interfollicular scaling in 100% (10/10) and 90% (9/10) of cases, respectively. On the other hand, in the group of patients with LPP, the most frequent findings were: fine perifollicular scaling in 100% (10/10) and linear, slightly branched vessels arranged concentrically around the follicular openings - both features observed also in 100% (10/10) of cases.Conclusion. Trichoscopy as a non-invasive diagnostic method may be helpful in differentiating non-scarring and scarring alopecia in the parietal area in women. Moreover, there are some trichoscopic features typical for AA, DLE and LPP, which allow for differentiation and facilitate the diagnosis of these entities.

Vascular Structures

Dermatoscopy is a valuable auxiliary non−invasive method used in the diagnosis of inflammatory, parasitic and viral skin diseases. Treatment of dermatoses is based on the results of analysis of melanin, follicular−horny and vascular components. Diagnosis begins with polarized dermatoscopy and then progresses to non−polarized using immersion fluid. At dermatoscopic inspection of a psoriatic plaque the point vessels evenly distributed along all the surface (a symptom of "scattered red pepper") are noted. Eczema is characterized by focal accumulation of blood vessels in the form of dots, peeling, yellowish crusts. Examination of discoid lupus erythematosus foci often reveals individual linear or branched vessels, their location is random. Red herpes zoster is dermatoscopically characterized by vascular structures in the form of large granular horny plugs of whitish color with a pearly sheen. The most informative is dermatoscopy in the differential diagnosis of erythematous form of rosacea and seborrheic dermatitis. On the erythematous background, dilated vessels around the sebaceous hair follicles, large vascular polygons formed from vessels thicker than in healthy skin and seborrheic dermatitis are found. At inspection of the fresh centers of a sclero−atrophic lichen diffuse unstructured zones of white color with a peripheral erythematous corolla and with numerous light comedic structures on a surface are visualized. At dermatoscopy of the Little − Lassueur syndrome in follicular papules on skin gray, violet points located in the form of a circle are noted. Dermatoscopy is increasingly used in dermatology, especially in the differential diagnosis of dermatoses of inflammatory and parasitic nature.

Specific Disease

Pseudopelade of Brocq is a clinical syndrome comprising of scarring alopecia and fibrosis in which distinct pathological features are absent. It is not a specific disease, rather a pattern of cicatricial alopecia. However, if a definitive diagnosis of DLE (discoid lupus erythematosus), LPP (Lichen planopilaris) or any other condition can be made on the basis of clinical, histopathological or immunofluorescent features, then this term cannot be used. Here we report the case of a 20 year old young male who presented to us with complaints of loss of scalp hair for 2 years which were associated with mild itching. The condition is as such rare in prevalence and hence we report the same in view of its unique presentation. DOI: http://dx.doi.org/10.3126/hren.v11i3.9652 Health Renaissance 2013;11(3):273-275

Bullous Skin Diseases

In a review of non-viral bullous skin diseases of domestic animals and a 4-year study of cases presented to the New York State College of Veterinary Medicine, we found 15 diseases: pemphigus vulgaris, pemphigus vegetans, pemphigus foliaceus, pemphigus erythematosus, bullous pemphigoid, systemic lupus erythematosus, dermatitis herpetiformis, toxic epidermal necrolysis, drug eruption, epidermolysis bullosa, epidermolysis bullosa simplex, familial acantholysis, bovine congenital porphyria, impetigo and subcorneal pustular dermatosis. The 15 diseases were placed in five categories: autoimmune, immune-mediated, hereditary, bacterial and idiopathic. A histologic classification of these disorders based on the site of blister formation and other important clinicopathologic, histologic and immunopathologic findings was developed.
