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)...

BACKGROUND: Pityriasis rosea (PR) is a common, acute, self-limiting inflammatory skin disease. It can easily be recognized with its typical clinical presentation. However, unusual clinic presentations can cause difficulty in diagnosis. Up to now, not many atypical forms are reported. OBJECTIVE: To determine the clinical characteristics of patients with atypical pityriasis rosea. METHODS: A total of 27 cases, diagnosed as atypical PR by clinical and/or histopathological examination and applied to the outpatient clinic of dermatology department between the years 2007 and 2015 were analyzed retrospectively...

Pityriasis rosea (PR) is an acute exanthematous skin disease that is likely due to reactivation of human herpesviruses (HHVs) 6b and 7. In contrast to herpes simplex and zoster (alphaherpesviruses), HHV-6b and -7 (betaherpesviruses) are not found predominantly in skin lesions. This difference in virion location may decrease the possibility of causing central nervous system infection through skin contamination, but the risk for hematogenous spread likely remains the same. This article uses the first-known epidural placement through active PR to illustrate risk-benefit considerations when deciding between neuraxial and general anesthesia for obstetric patients with PR...

Pityriasis rosea (PR) is a benign papulosquamous disorder seen commonly in clinical practice. Despite its prevalence and benign nature, there are still times when this common disorder presents in an uncommon way or course posing diagnostic or management problems for the treating physician. The etiopathogenesis of PR has always been a dilemma, and extensive research is going on to elicit the exact cause. This review focuses mainly on the difficult aspects of this benign common disorder such as etiopathogenesis, atypical manifestations, recurrent cases, differential diagnosis, therapy and pregnancy considerations...

INTRODUCTION: Papulosquamous diseases are characterized by scaly papules and plaques with similar clinical picture which amounts to confusion and hence, a definitive histopathological diagnosis goes a long way in treatment of such diseases. AIM: The aim of the study was to study the histomorphology of non-infectious, erythaematous, papulosquamous lesions of skin with clinicopathological correlation. MATERIALS AND METHODS: Skin biopsies from 150 clinically diagnosed/suspected non-infectious erythaematous, papulosquamous skin diseases were received in the Department of Pathology...

Many clinical trials have been conducted on the treatment of pityriasis rosea (PR). Our aim was to establish a position statement for the management of adults with PR based on the best available evidence. We searched PubMed for all reports on randomized controlled trials for the treatment of PR published in the past 30 years. We retrieved 14 articles reporting randomized controlled trials, and found five which met our quality requirements for in-depth analyses. Erythromycin was found in a well-conducted triple-blind study to cast significant impacts on clinical outcomes...

An 18-month-old girl presented with pityriasis rosea gigantea. The herald patch encircled almost the entire trunk. The distribution of lesions on the trunk and proximal aspects of the limbs, the collarette scaling, the orientation of some lesions along the skin crease lines, and biopsy findings substantiated the diagnosis.

A switch from cell-mediated to humoral immunity (helper T 1 [Th1] to helper T 2 [Th2] shift) during gestation plays a key role in placental immune tolerance. As a result, skin diseases that are Th2 mediated often worsen, whereas skin diseases that are Th1 mediated often improve during gestation. Also, due to fluctuations in glandular activity, skin diseases involving sebaceous and eccrine glands may flare, whereas those involving apocrine glands may improve during pregnancy. Despite these trends, inflammatory and glandular skin diseases do not always follow the predicted pattern, and courses are often diverse...

BACKGROUND: Pityriasis rosea (PR) is an inflammatory skin disorder of unknown etiology. However, it is suggested to be related with the reactivation of human herpes virus 7 (HHV-7) and/or HHV-6. It is sometimes diffucult to distinguish PR from PR-like drug eruptions and other inflammatory disorders, so we need new parameters which are cheap and easy in determining PR. Red blood cell distribution width (RDW) and mean platelet volume (MPV) have been studied as inflammatory markers in recent studies...

Many clinical and laboratory-based studies have been reported for skin rashes which may be due to viral infections, namely pityriasis rosea (PR), Gianotti-Crosti syndrome (GCS), asymmetric periflexural exanthem/unilateral laterothoracic exanthem (APE/ULE), papular-purpuric gloves and socks syndrome (PPGSS), and eruptive pseudo-angiomatosis (EP). Eruptive hypomelanosis (EH) is a newly discovered paraviral rash. Novel tools are now available to investigate the epidemiology of these rashes. To retrieve epidemiological data of these exanthema and analyze whether such substantiates or refutes infectious etiologies...

Pityriasis rosea (PR) is an acute, self-limiting exanthematous disease associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and/or HHV-7. The disease typically begins with a single, erythematous plaque followed by a secondary eruption with lesions on the cleavage lines of the trunk (configuration of a 'Christmas tree'). The duration may vary from 2 weeks to a few months. Besides the typical presentation of PR, atypical forms have been described. The previous classifications of PR are mainly based on its atypical morphological features rather than on the pathogenetic mechanisms that underlie the different presentations of the disease...

Many skin and skin-related diseases affect the sexes unequally, with attendant implications for public health and resource allocation. To evaluate better the incidence of skin and skin-related diseases affecting males vs. females, we reviewed published population-based epidemiology studies of skin disorders performed utilizing Rochester Epidemiology Project data. Females had a higher incidence of the following diseases: connective tissue diseases (scleroderma, morphea, dermatomyositis, primary Sjögren syndrome, systemic lupus erythematosus [not in all studies]), pityriasis rosea, herpes progenitalis, condyloma acuminatum, hidradenitis suppurativa, herpes zoster (except in children), erythromelalgia, venous stasis syndrome, and venous ulcers...

BACKGROUND: Pityriasis rosea (PR) is usually an asymptomatic and self-limiting papulosquamous skin disease with acute onset. The etiology has not been clarified yet. Recently, increased oxidative stress was found to play a role in etiopathogenesis of multiple cutaneous diseases with T cell-mediated immune response. However, there are no studies demonstrating the oxidative stress status in PR. AIM: The aim of the study is to determine the status of oxidative stress (OS) and paraoxonase (PON) 1/arylesterase enzyme activities in PR...

For many years, the biblical term tzaraat has referred to leprosy. In fact, the disease or diseases described under this name have no relationship to leprosy, as it was known in the Middle Ages or today; moreover, the term referred not only to skin disease, but also to the state of the ritual impurity and punishment for the sins. Although the real nature of tzaraat remains unknown, the differential diagnosis might include the following: Psoriasis, seborrheic dermatitis, favus, dermatophyte infections, nummular dermatitis, atopic dermatitis, pityriasis rosea, crusted scabies, syphilis, impetigo, sycosis barbae, alopecia areata, furuncles, scabies, neurodermatitis, scarlet fever, lupus erythematosus, lichen sclerosus et atrophicus, folliculitis decalvans, morphea, sarcoidosis, and lichen planopilaris...
