Spiny keratoderma: Report of three cases.

Background: Spiny keratoderma shows "music box spine" keratotic papules limited to the palms and soles and these lesions do not cause any trouble besides the cosmetic impairment and the sensation of roughness of hands and soles.

Aim: To present cases and review the literature on spiny keratoderma.

Patients/methods, Results: Three cases of spiny keratoderma are presented.

Clinical-histopathological profile of the frontal fibrosing alopecia: a retrospective study of 16 cases of a university hospital.

Background: Frontal fibrosing alopecia is a condition of unknown origin, histologically similar to classic lichen planopilaris and generally observed in postmenopausal women with alopecia of the frontal-temporal hairline.

Objectives: To describe the clinical, dermatoscopic, and histopathological characteristics and the treatment used in patients who have frontal fibrosing alopecia at the Alopecia Outpatient Clinic in a university hospital.

Methods: Retrospective descriptive study performed by reviewing medical charts and biopsies of the scalp.

Flagellate Dermatitis by Shiitake Mushroom.

The authors present a case of flagellate dermatitis in a previously healthy young male, triggered by the consumption of shiitake mushrooms. Complete remission without complications was obtained within 7 days, simply by the application of dexamethasone cream 0.1%.

Disseminated Strongyloidiasis.

Strongyloidiasis is a parasitic infestation caused by the helminth Strongyloides stercoralis. It is essentially gastrointestinal and in general asymptomatic but can sometimes present with skin signs. Immunocompromised patients can develop the disseminated form of the disease due to the parasite's opportunistic behavior, as in cases of coinfection by the human T-lymphotropic type 1 virus (HTLV-1).

Churg-Strauss Syndrome or Eosinophilic Granulomatosis with Polyangiitis: Exuberant Classic Clinical Picture of a Rare Disease.

The authors present a classic case of Churg-Strauss syndrome with an exuberant clinical picture in a 34-year-old woman. She showed the following diagnostic criteria: asthma, polyneuropathy, rhinopathy, marked eosinophilia, positive p-ANCA with a perinuclear pattern, and skin histopathology results suggestive of vasculitis with eosinophils. There was a good response to prednisone, dexamethasone pulse therapy, and cyclophosphamide.

Psoriasiform Eruption Secondary to the Use of Adalimumab.

Induced psoriasiform eruption, especially by anti-tumor necrosis factor alpha, was a rather rare event but nowadays cases are increasing because of its prescription for many different diseases. There are several clinical forms; one example is the pustulosis form presented in this case report.

Dermatoscopic findings as a complementary tool in the differential diagnosis of the etiological agent of tinea capitis.

Tinea capitis is a scalp infection caused by fungi. In Brazil, the main causative agents are Microsporum canis and the Trichophyton tonsurans. Etiological diagnosis is based on suggestive clinical findings and confirmation depends on the fungus growth in culture.

Cutaneous Manifestations in POEMS Syndrome: Case Report and Review.

The authors report a case of sensorimotor polyneuropathy, diffuse cutaneous hyperpigmentation, skin sclerodermiform thickening and papular lesions in the infraclavicular and abdominal region. Besides weight loss, there were diabetes mellitus and hypothyroidism. The alterations were consistent with POEMS (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy and Skin changes) syndrome, which is a rare systemic disease with monoclonal proliferation of plasmacytes and slow progression.

Alopecia secondary to anti-tumor necrosis factor-alpha therapy.

Biologic drugs represent a substantial progress in the treatment of chronic inflammatory immunologic diseases. However, its crescent use has revealed seldom reported or unknown adverse reactions, mainly associated with anti-tumor necrosis factor (anti-TNF). Psoriasiform cutaneous reactions and few cases of alopecia can occur in some patients while taking these drugs.

Oleoma treated with oral colchicine: Report of two cases and review of the literature.

Oleoma is a non-allergic, foreign body type granulomatous reaction. It appears as response to oily exogenous substances injected to the dermis or subcutis for aesthetical purposes. Treatment for localized lesions is surgical.

Quality of life in alopecia areata: a case-control study.

Background: Although alopecia areata (AA) is typically seen by medical staff as a benign, not life-threatening cosmetic disease, some studies have found significant impairment in quality of life (QL) in AA patients. There are no studies that assess QL in Brazilian AA patients.

Objectives: To evaluate QL in AA patients, using the 36-item Short-Form Health Survey (SF-36).

Follicular red dots: a normal trichoscopy feature in patients with pigmentary disorders?

Follicular red dots have been described as a trichoscopic feature of active discoid lupus erythematosus of the scalp and its presence associated with a better prognosis. We report five patients with pigmentary disorders in whom follicular red dots were detected during scalp examination. We suggest that this pattern is probably related to the rich vasculature that naturally envelops the normal hair follicle.

Disseminated fusariosis in a bone marrow transplant patient.

The authors present a case report involving an immunocompromised patient with fusariosis, an often fatal fungal infection in this group of patients. This mycosis needs to be recognized and treated in the initial phases, although this does not guarantee improvement.

Polycystic ovary syndrome: a dermatologic approach.

Polycystic ovary syndrome (POS) is one of the most common endocrine abnormalities affecting women of reproductive age. It is a cause of significant social embarrassment and emotional distress. The pathogenesis of the disease is not yet fully understood, but it is thought to be a complex multigenic disorder, including abnormalities in the hypothalamic-pituitary axis, steroidogenesis, and insulin resistance.

Dermoscopy patterns of cicatricial alopecia resulting from discoid lupus erythematosus and lichen planopilaris.

Background: Dermoscopy is an important tool for the diagnosis of benign and malignant melanocytic diseases. Recently, this method has also been found to be extremely useful in the diagnosis and follow-up of alopecias.

Objective: The objective of this study was to describe dermoscopic findings in patients with clinical and histopathological characteristics of cicatricial alopecia.

Dermoscopy findings of alopecia areata in an African-American patient.

Background: Dermoscopy has been established as an indispensable tool in the diagnosis and follow up of hair disorders. In alopecia areata, dermoscopy of active disease shows yellow dots, dystrophic hairs, as well as cadaverized (black dots) and exclamation mark hairs. Alopecia areata has been reported to occur equally among races, however, until date, there are no published data regarding dermoscopic findings in African-American patient.
