Consensus on the therapeutic management of atopic dermatitis - Brazilian Society of Dermatology.

Background: Atopic dermatitis is a highly prevalent inflammatory and pruritic dermatosis with a multifactorial etiology, which includes skin barrier defects, immune dysfunction, and microbiome alterations. Atopic dermatitis is mediated by genetic, environmental, and psychological factors and requires therapeutic management that covers all the aspects of its complex pathogenesis.

Objectives: The aim of this article is to present the experience, opinions, and recommendations of Brazilian dermatology experts regarding the therapeutic management of atopic dermatitis.

Atypical Gianotti-Crosti syndrome.

We report the case of a male 22-month-old child, with atypical presentation of Gianotti-Crosti syndrome after infection with Epstein-Barr virus.

Pyoderma gangrenosum associated with left iliac vein compression syndrome: presentation of difficult diagnosis.

Pyoderma gangrenosum is a rare neutrophilic dermatosis of unknown etiology, of which the most frequent clinical manifestations are ulcers. The diagnosis difficulty is, among other things, to rule out other causes of ulcers, since it is considered a diagnosis of exclusion. Skin ulcerations may also occur in the iliac vein compression syndrome, which, like pyoderma gangrenosum, mainly affects young women.

Elastoma: clinical and histopathological aspects of a rare disease.

Elastoma is a connective tissue nevus characterized by changes in elastic fibers. It can be congenital or acquired, and is usually diagnosed before puberty. Associated with osteopoikilosis, it is known as Buschke-Ollendorff syndrome.

Generalized Lichen nitidus associated with Down's syndrome: case report.

Lichen nitidus is a disease of unknown etiology, characterized by flesh-colored, shiny papules of 1-2 mm and generally asymptomatic or with mild pruritus. The most common sites of occurrence are genitalia, upper limbs, trunk and abdomen. The generalized form is rare.

Do you know this syndrome? Chediak-Higashi syndrome.

Chediak-Higashi syndrome is characterized by varying degrees of oculocutaneous albinism, recurrent infections, bleeding disorders and variable neurological involvement. The treatment consists of bone marrow transplantation, which corrects the immunologic and hematologic defects. Untreated patients die as the result of bacterial infections or develop "accelerated phase" lymphoproliferation.

A study of the correlation between molluscum contagiosum and atopic dermatitis in children.

Background: Although no scientific evidence has yet been published, it is widely understood that molluscum contagiosum tends to be more common and more intense in patients with atopic dermatitis. This lack of evidence led to the development of the present study.

Objectives: To evaluate the prevalence of the association between atopic dermatitis and molluscum contagiosum; to evaluate whether molluscum contagiosum is more likely to be recurrent and/or disseminated in patients with atopic dermatitis and whether the occurrence of eczema surrounding the molluscum contagiosum lesions, pruritus and/or infection is more prevalent in these patients compared to patients without atopic dermatitis.

Dermoscopic patterns of molluscum contagiosum: a study of 211 lesions confirmed by histopathology.

Backgrounds: Although easily diagnosed, molluscum contagiosum may present as a single lesion or as several small, inflamed lesions of difficult diagnosis.

Objective: To describe the dermoscopic characteristics of molluscum contagiosum and to compare the findings from clinical examination and dermoscopy.

Methods: Histopathologically confirmed lesions were evaluated clinically and dermoscopically in 57 patients.

[Familial aquagenic urticaria: report of two cases and literature review].

Aquagenic urticaria is a rare form of physical urticaria, characterized by pruritic wheals that appear following contact with water, independently of its temperature. There are few reports of cases of aquagenic urticaria, and only five include the familial form. We present the first case of familial aquagenic urticaria in Brazil (mother and daughter).
