Objectives: To evaluate the prevalence of methylisothiazolinone sensitivity and associated factors in individuals with suspected allergic contact dermatitis.

Methods: Cross-sectional study based on patch tests, including methylisothiazolinone 0.2%, in 286 participants with suspected allergic contact dermatitis, in Brasília/DF, Brazil, between March/2020 and March/2022.

Allergic contact cheilitis caused by propolis: case report.

Propolis is a lipophilic resin extracted from plants by bees. The purpose of this case report was to show the importance of this substance as cause of allergic contact cheilitis. A 21-year-old female patient complained of pruritic perioral eczema for 5 years.

Severe varicella in a child immunosuppressed with methotrexate.

Varicella is a common viral infection in childhood and usually has a benign evolution. However, the evolution can be severe in immunosuppressed children. Vaccination can prevent its occurrence and especially the development of severe and/or complicated cases.

A novel genomic variant in Midwestern Brazil: evidence for an older and wider sporotrichosis epidemic.

Sporotrichosis is a subcutaneous infection caused by fungi from the genus . It is transmitted by inoculation of infective particles found in plant-contaminated material or diseased animals, characterizing the classic sapronotic and emerging zoonotic transmission, respectively. Since 1998, southeastern Brazil has experienced a zoonotic sporotrichosis epidemic caused by , centred in the state of Rio de Janeiro.

Mycetomas: an epidemiological, etiological, clinical, laboratory and therapeutic review.

Mycetoma is a chronic suppurative disease of the skin and subcutaneous tissue, characterized by a symptomatic triad: tumor, fistulas and grains. It can be caused by fungi (eumycetoma) and bacteria (actinomycetoma), with similar clinical features. Diagnosis is based on the clinical presentation and identification of the etiological agents in the tissue, by mycological/bacteriological, histopathological and immunohistochemical tests.

Case for diagnosis.

Idiopathic Atrophoderma of Pasini and Pierini (IAPP) is a rare, exclusively cutaneous disease. It is more frequent in females, with incidence peak in the second and third decades of life. The etiopathogenesis remains unknown.

Bullous pemphigoid in a 3-month-old infant: case report and literature review of this dermatosis in childhood.

Bullous pemphigoid is an autoimmune subepidermal blistering dermatosis that is uncommon in childhood. We report a case of a female infant, 3 months old, which presented clinical and laboratory data for the confirmatory diagnosis of bullous pemphigoid. The authors used immunohistochemical staining for collagen type IV that allowed the differentiation of bullous pemphigoid from other subepidermal bullous diseases.

Do you know this syndrome?

The hyperimmunoglobulin E syndrome, or Job's syndrome is a rare primary immunodeficiency characterized by recurrent skin abscesses, recurrent respiratory tract infections, and high levels of IgE, eosinophilia, bone and dental changes. We report the case of a fourteen-year-old male patient presenting this disease, with both typical and also some relatively sporadic manifestations. We performed a literature review on the syndrome and its associated clinical findings.

Study of dermatoses in kidney transplant patients.

Background: The increasing in the number of kidney transplant recipients has favored, more frequently than before, the emergence of dermatoses and warranted their study through subsequent publications.

Objectives: to evaluate the frequency of dermatoses in kidney transplant recipients.

Methods: kidney transplant recipients with suspected dermatoses between March 1st 2009 and June 30th 2010.

Infection of the lymphatic system by Aureobasidium pullulans in a patient with erythema nodosum leprosum.

Aureobasidium pullulans is a causal agent of phaeohyphomycosis, occasionally found in men and animals. As an agent of different opportunistic fungal processes, it may cause fungemia, systemic infections and abscesses in different viscera. This paper aims to report a case of a patient with infection of the lymphatic system by A.

Case for diagnosis. Steatocystoma multiplex.

Steatocystoma multiplex is a rare genetic disorder, autosomal dominant, that is characterized by multiple asymptomatic dermal cysts which vary in size. It is described here the case of a 23 year-old male patient with a typical clinical and evolutional progression of this disease.

The pattern of immune cell infiltration in chromoblastomycosis: involvement of macrophage inflammatory protein-1 alpha/CCL3 and fungi persistence.

Chromoblastomycosis (CR) is a subcutaneous chronic mycosis characterized by a granulomatous inflammatory response. However, little is known regarding the pattern of leukocyte subsets in CR and the pathways involved in their recruitment. The objective of this study was to assess the cellular subsets, chemokine, chemokine receptors and enzymes in CR.
