Frontal fibrosing alopecia is a disease characterized by a symmetric and progressive loss of hair in the fronto-temporal and fronto-parietal lines that generally affects postmenopausal women. It is considered a variant of lichen planus pilaris for its clinical and histopathological features; although, its etiopathology is still unknown. In this report, we analyzed 4 cases of this disease and we discussed its clinical and histopathological characteristics, as well as their course after initiating treatment.

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)...

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...

BACKGROUND: Recently developed tyrosine kinase inhibitors (TKIs) offer first-line alternatives to patients with chronic myeloid leukemia. While these medications are generally well tolerated, cutaneous reactions occur frequently and can present a management challenge. We describe a newly recognized skin reaction to dasatinib and nilotinib and extend it to the newer agent ponatinib. OBSERVATIONS: Nine patients developed varying degrees of a clinically and histopathologically lichenoid exanthem comprised of erythematous, predominately follicular papules with scale and alopecia...

Graham-Little-Piccardi-Lasseur Syndrome (GLPLS) is a variant of lichen planopilaris, which is characterized by progressive cicatricial alopecia of scalp, non-cicatricial alopecia of axillae and pubic regions, and keratosis pilaris-like follicular papules over trunk and extremities. GLPLS is a disease of unknown etiology. However, recent reports support a central role for a T-cell-mediated immune response in the pathogenesis of GLPLS. Besides, although GLPLS is believed to occur sporadically, a genetic predisposition also has been implicated in the pathogenesis...

Beside 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...

A neutral cysteine protease, bleomycin hydrolase (BH), is widely expressed in mammalian tissues, with the skin seeming to contain the highest level. Our previous study revealed that BH transcription is modulated both during differentiation and by cytokines. However, BH involvement in keratinization disorder is not well known. In the present study, we performed immunohistochemical studies of BH and other serine/cysteine proteases in human normal skin and lesional skin with keratinization disorders. BH-positive cells were detected in granular layers of orthokeratotic and hyperkeratotic skin diseases, such as erythrokeratoderma and lichen planus...

BACKGROUND: Fumarates are approved for the systemic treatment of moderate and severe psoriasis vulgaris in Germany. However, a number of studies and case reports indicate their efficacy in the treatment of further inflammatory skin disorders or granulomatous skin diseases. OBJECTIVES: To examine the efficacy and safety of fumarates for the treatment of granulomatous and inflammatory skin diseases other than psoriasis vulgaris. PATIENTS AND METHODS: The therapeutic efficacy and side-effects of fumarate therapy were analysed retrospectively in patients with granuloma annulare (GA, n = 4), cutaneous sarcoidosis (SA, n = 1), lichen planus (LP, n = 3), pityriasis rubra pilaris (PRP, n = 1) or chronic discoid lupus erythematosus (CDLE, n = 1)...

INTRODUCTION: Papulo-squamous skin diseases are variable but are very close in their clinical features. They present with the same lesions, erythematous scaly lesions. Clinical evaluation of skin lesions is based on common sense and experience of the dermatologist to differentiate features of each disease. AIM: To evaluate a computer-based image analysis system as a helping tool for classification of commonly encountered diseases. MATERIALS AND METHODS: The study included 50 selected images from each of psoriasis, lichen planus, atopic dermatitis, seborrheic dermatitis, pityrasis rosea, and pitryasis rubra pilaris with a total of 300 images...

Lichen planus is considered a T cell-mediated immunological disease. Even mast cells may contribute to the pathogenesis of the disease. Keratinocytes of the basal layer of the skin and/or the hair follicle may represent the "target/victim" of an immune aggression, determining the destruction of the hair follicle and thus scarring alopecia. Therefore, there is a compelling urgency for effective treatment of this potentially disfiguring dermatosis. Our data provide a further therapeutic opportunity: the use of an antihistaminic drug--cetirizine (CTZ)--in an "anti-inflammatory" regimen...

BACKGROUND: Scarring alopecias are classified into primary and secondary types according to the initial site of inflammation. In primary scarring alopecias, the hair follicle is the main target of destruction; the term secondary cicatricial alopecia implies that follicular destruction is not the primary pathologic event. AIMS: To review the histopathologic diagnoses of cases of cicatricial alopecia in order to classify them according to the North American Hair Research Society...

In a previous search for the differentially expressed genes in keratinocyte differentiation, we identified neutrophil gelatinase-associated lipocalin (NGAL) as a calcium-induced gene. In this study, we further verified the expression of NGAL in cultured keratinocytes as well as in several skin diseases. Reverse transcription-polymerase chain reaction (RT-PCR), Western blot, and ELISA clearly showed that NGAL expression was markedly increased in calcium-induced keratinocyte differentiation in vitro. However, in our previous report, NGAL expression was not detected in normal skin tissue except for hair follicle by in situ hybridization and immunohistochemistry, indicating the difference of cell status between in vitro and in vitro conditions...

Systemic isotretinoin has been used to treat severe acne vulgaris for 20 years. However, isotretinoin also represents a potentially useful choice of drugs in many dermatologic diseases other than acne vulgaris. Diseases such as psoriasis, pityriasis rubra pilaris, condylomata acuminata, skin cancers, rosacea, hidradenitis suppurativa, granuloma annulare, lupus erythematosus and lichen planus have been shown to respond to the immunomodulatory, anti-inflammatory and antitumor activities of the drug. Isotretinoin also helps prevent skin cancers such as basal cell carcinoma or squamous cell carcinoma...

Lassueur-Graham-Little-Piccardi syndrome (LGLPS) is a rare lichenoid dermatosis characterized by progressive cicatricial alopecia of the scalp, loss of pubic and axillary hairs and keratosis pilaris. The syndrome is considered a form of follicular lichen planus (LP). Although the familial occurrence of LP is a well-described phenomenon, no familial case of LGLPS has ever been reported. We describe the occurrence of LGLPS in a mother and her daughter. HLA typing revealed HLA-DR1 in both patients. Topical tacrolimus was of partial benefit in the daughter...
