Congenital Syringocystadenoma Papilliferum

O siringocistoadenoma papílifero é uma neoplasia anexial benigna incomum, que se localiza preferencialmente no couro cabeludo e face, e está associado ao nevo sebáceo em 40% dos casos. Embora rara, a transição para carcinoma basocelular e carcinoma ductal pode ocorrer. Os autores descrevem o caso de um paciente do sexo masculino, de 7 anos de idade, com dermatose papulosa linear do pescoço desde o nascimento. Apresentava, no exame dermatológico, pápulas eritematosas, crateriformes, confluentes, dispostas em faixa, de 3 x 2 cm na região cervical. Foi realizada a exérese da lesão e o exame histopatológico demonstrou invaginação cística epidérmica e projeções papilares revestidas por epitélio glandular, com secreção de decapitação e infiltrado linfo-plasmocitário abundante. Os achados clínicos e histológicos foram compatíveis com o diagnóstico de siringocistoadenoma papílifero. Apesar da variabilidade clínica desta entidade, a histopatologia é característica e o tratamento consiste na exérese da lesão.Papillary syringocystoadenoma is an uncommon benign adnexal neoplasm, which is preferentially located on the scalp and face, and is associated with sebaceous nevus in 40% of cases. Although rare, its transition to basal cell carcinoma and ductal carcinoma may occur. The authors describe the case of a 7-year-old male patient with a linear papular dermatosis in the neck from birth. Dermatological examination showed erythematous, crateriform, confluent papules, arranged in a band, 3 x 2 cm in the cervical region. The lesion was excised for therapeutic and diagnostic purposes. Histopathology demonstrated epidermal cystic invagination and papillary projections surface by glandular epithelium, with decapitation secretion and abundant lymphoplasmocytic infiltrate. The clinical and histological findings were compatible with the diagnosis of papillary syringocystoadenoma. Despite the clinical variability of this entity, the histopathology is characteristic and the treatment consists in the excision of the lesion

Atopic Eczema Simulating Mammary Paget’s Disease in an Adult: Case Report

An atopic breast eczema is usually bilateral, with intense pruritus and good response to corticosteroids. The differential diagnosis with mammary Paget’s disease is fundamental, mainly in unilateral clinical manifestations, since it is frequently associated to adjacent breast tumors. The aim of the present report was to present a clinical condition of an atopic breast eczema through an exuberant and unilateral clinical presentation, emphasizing the need of the differential diagnosis for malignant diseases at this location

Inflammatory linear verrucous epidermal nevus and differential diagnosis with linear psoriasis

           Inflammatory Linear Verrucous Epidermal Nevus (ILVEN) is a rare clinical variety of verrucous epidermal nevus that manifests in early childhood as inflammatory lesions of keratosis surface, which coalesce and spread in band, following Blaschko lines. It makes a differential diagnosis with Linear Psoriasis; it is difficult to differentiate them given the clinical and histopathological aspects common to both, emphasizing the need to know the specific characteristics of each. The purpose of this report is to demonstrate a relatively rare affection, expressed in a 5-year-old girl, evolving from the first days of life with papulokeratosic plaques arranged linearly, followed by inflammatory signs and eroded areas, placed linearly, overtaking labia majora, perineum, the inner and upper face of the left thigh. Also, the patient showed keratotic papules and plaques in the posterior cervical region and external lateral border of the left foot plant, ascending along the posterior region of this limb. The clinical and histopathological criteria corroborate the diagnosis of ILVEN in differentiation with linear psoriasis, emphasizing the importance of establishing criteria/instruments to assist in distinguishing these two dermatoses in order to expedite the diagnosis, to optimize the treatment and minimize patients’ discomfort. Long-term follow-up of patients with this disease is suggested due to the possibility, albeit minimal, of ILVEN malignancy.O nevo epidérmico verrucoso inflamatório linear (NEVIL) é uma variedade clínica rara de nevo epidérmico verrucoso, que se manifesta no início da infância, como lesões inflamatórias de superfície ceratósica, que coalescem e se distribuem em faixa, acompanhando as linhas de Blaschko. Faz diagnóstico diferencial com a psoríase linear, sendo difícil a diferenciação, dado os aspectos clínicos e histopatológicos comuns aos dois, enfantizando-se a necessidade de conhecer as características específicas de cada um. O objetivo deste relato é demonstrar uma afecção relativamente rara, descrita em uma  menina de 5 anos, evoluindo desde os primeiros dias de vida com placas papuloceratósicas dispostas linearmente, acompanhadas de sinais inflamatórios e áreas erosadas ocupando grandes lábios, períneo e face interna e superior da coxa esquerda. Também pápulas e placas ceratósicas na região cervical posterior e borda lateral externa da planta do pé esquerdo, ascendendo ao longo da região posterior deste membro. Os critérios clínicos e histopatológicos corroboram o diagnóstico de NEVIL na diferenciação com a psoríase linear, ressaltando a importância do estabelecimento de critérios/ ferramentas que auxiliem na diferenciação destas duas dermatoses visando agilizar o diagnóstico, otimizar o tratamento e minimizar o desconforto para esses pacientes. O acompanhamento a longo prazo dos portadores é sugerido pela possibilidade ainda que mínima de malignização do NEVIL

Clinical, epidemiological, and therapeutic profile of dermatophytosis

BACKGROUND: The cutaneous mycoses, mainly caused by dermatophyte fungi, are among the most common fungal infections worldwide. It is estimated that 10% to 15% of the population will be infected by a dermatophyte at some point in their lives, thus making this a group of diseases with great public health importance. OBJECTIVE: To analyze the clinical, epidemiological, and therapeutic profile of dermatophytosis in patients enrolled at the Dermatology service of Universidade do Estado do Pará, Brazil, from July 2010 to September 2012. METHOD: A total of 145 medical records of patients diagnosed with dermatophytosis were surveyed. Data were collected and subsequently recorded according to a protocol developed by the researchers. This protocol consisted of information regarding epidemiological and clinical aspects of the disease and the therapy employed. RESULTS: The main clinical form of dermatophyte infection was onychomycosis, followed by tinea corporis, tinea pedis, and tinea capitis. Furthermore, the female population and the age group of 51 to 60 years were the most affected. Regarding therapy, there was a preference for treatments that combine topical and systemic drugs, and the most widely used drugs were fluconazole (systemic) and ciclopirox olamine (topical). CONCLUSION: This study showed the importance of recurrent analysis of the epidemiological profile of dermatophytosis to enable correct therapeutic and preventive management of these conditions, which have significant clinical consequences, with chronic, difficult-totreat lesions that can decrease patient quality of life and cause disfigurement
