ABSTRACT

Abstract Background: Currently, there is no uniform and official terminology in Portuguese for reflectance confocal microscopy analysis, despite the increasing number of Brazilian dermatologists using this new tool. Objective: To present the terminology in Brazilian Portuguese for the description of reflectance confocal microscopy and establish the first Brazilian consensus on terms related to normal skin and cutaneous tumors. Methods: 10 Brazilian specialists from different institutions and states of Brazil were selected to evaluate the best corresponding terms in Portuguese for normal skin, melanocytic and non-melanocytic tumors. The terms used were translated from international consensuses in the English language. The modified Delphi method was used to create the consensus in 3 steps. Results: The terms considered the most appropriate in the Portuguese language to describe the findings of normal skin, melanocytic and non-melanocytic lesions in the reflectance confocal microscopy analysis were presented. Study limitations: The limitations of the present study include the number of participants and limited regional representation (only two of the five Brazilian regions were represented). Conclusion: This Brazilian consensus represents an opportunity for dermatologists and physicians specializing in cutaneous oncology to become familiar with reflectance confocal microscopy, propagating the technique in clinical and research environments to stimulate national and international publications on this subject.

ABSTRACT

Neste estudo transversal, comparamos o diagnóstico feito por meio da teledermatoscopia ao diagnóstico histopatológico. Fotos convencionais e dermatoscópicas de 31 lesões pigmentadas foram enviadas a um dermatologista experiente por meio do aplicativo WhatsApp® Messenger. Todas as lesões foram excisadas e examinadas por um dermatopatologista. A acurácia global da teledermatoscopia móvel foi de 90,32%. Em relação à capacidade de a teledermatoscopia definir malignidade da lesão pigmentada, a especificidade foi de 81,8% e a sensibilidade de 100%. Nossos resultados fornecem evidências adicionais sobre a confiabilidade da teledermatoscopia móvel, com alta sensibilidade e precisão.


In this cross-sectional study, we compared the diagnosis made through teledermatoscopy with histopathological diagnosis. Conventional and dermoscopic photos of 31 pigmented lesions were taken and sent to an experienced dermatologist using the WhatsApp® Messenger application. A dermatopathologist excised and examined all lesions. The global accuracy of mobile teledermatoscopy was 90.32%. Regarding the ability of teledermatoscopy to define malignancy of the pigmented lesion, the specificity was 81.8% and the sensitivity was 100%. Our results provide additional evidence of the reliability of mobile teledermatoscopy with high sensitivity and accuracy.

ABSTRACT

Abstract: Atrophoderma of Pasini and Pierini is a skin disorder affecting dermal collagen and is clinically characterized by well-defined plaques of depressed skin. Histopathological changes are subtle, and in most cases, the diagnosis requires a comparative study with healthy skin from the same anatomical site. High frequency ultrasound is a useful imaging method for diagnosis of atrophic skin changes. A case is presented in which ultrasound can support the clinical and the histopathological diagnosis of atrophoderma of Pasini and Pierini.

ABSTRACT

Abstract: Ultrasonography is a method of imaging that classically is used in dermatology to study changes in the hypoderma, as nodules and infectious and inflammatory processes. The introduction of high frequency and resolution equipments enabled the observation of superficial structures, allowing differentiation between skin layers and providing details for the analysis of the skin and its appendages. This paper aims to review the basic principles of high frequency ultrasound and its applications in different areas of dermatology.

ABSTRACT

AbstractThe present essay is aimed at getting the radiologist familiar with the basic histological skin structure, allowing for a better correlation with sonographic findings. A high-frequency (22 MHz) ultrasonography apparatus was utilized in the present study. The histological analysis was performed after the skin specimens fixation with formalin, inclusion in paraffin blocks and subsequent staining with hematoxylin-eosin. The authors present a literature review showing the relationship between sonographic and histological findings in normal cutaneous tissue, and discuss the technique for a better performance of the sonographic scan. High-frequency ultrasonography is an excellent tool for the diagnosis of different skin conditions. However, as this method is operator-dependent, it is crucial to understand the normal skin structure as well as the correlation between histological and sonographic findings.


ResumoO objetivo deste trabalho é familiarizar o radiologista com a estrutura histológica cutânea, o que torna possível uma melhor correlação dos achados ultrassonográficos da pele. Para o exame radiológico foi utilizado aparelho de ultrassom de alta frequência (22 MHz). O exame histológico foi realizado após fixação do material em formol, inclusão em parafina e coloração com hematoxilina-eosina. Os autores fazem uma revisão da literatura, demonstram a relação dos achados ultrassonográficos e histológicos do tecido cutâneo normal e discutem a técnica para o melhor aproveitamento do exame ultrassonográfico da pele. O ultrassom de alta frequência representa uma excelente ferramenta no diagnóstico das diferentes alterações cutâneas. Como o método é operador-dependente, é crucial o perfeito entendimento da pele normal e sua equivalência histológica/ultrassonográfica.

ABSTRACT

Abstract

Collision tumors are characterized by the coexistence of two cancers in the same anatomical site and its pathogenesis remains controversial. Although uncommon, the association of basal cell carcinoma and melanocytic nevus is the most common among combinations of skin tumors. Even rarer is the association of two malignant tumors. We report a case of tumor collision representing melanoma and basosquamous cell carcinoma, a combination not previously described in the literature, since there are no reported cases of melanoma with this type of basal cell carcinoma.

ABSTRACT

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. Two cases of alopecia were reported after anti-TNF therapy. Both also developed psoriasiform lesions on the body. This is the second report about a new entity described as 'anti-TNF therapy-related alopecia', which combines clinical and histopathological features of both alopecia areata and psoriatic alopecia. The recognition of these effects by specialists is essential for the proper management and guidance of these patients.

ABSTRACT

Pigmented Bowen's disease is rare, though more prevalent in men. It presents as a well-delineated plaque in areas unexposed to sun. There are reports of association with seborrheic keratosis, solar lentigo or exuberant pigmentation of genital and intertriginous regions. A specific dermoscopy finding is the presence of brown or gray dots in regular arrangement and coiled or dotted vessels. Thus, we aim to raise awareness of the diagnosis of pigmented Bowen's disease in pigmented lesions.

ABSTRACT

Lichen aureus is a rare variant of pigmented purpura, with a chronic and benign course. It is generally asymptomatic and often occurs in the lower limbs, presenting as erythematous brownish, coppery or golden macules and/or papules. The diagnosis is based on clinical and histopathological findings. The dermatoscopic pattern has been considered a useful tool in diagnosis presumption. We describe a case with a confluent morphological pattern, called agminate lichen aureus.


O líquen aureus é uma variante rara das púrpuras pigmentares, com evolução crônica e benigna. A maioria é assintomática e predomina nos membros inferiores. O quadro clínico é constituído por máculas e/ou pápulas eritemato-acastanhadas, acobreadas ou douradas. O diagnóstico é clínico e histopatológico, porém o padrão dermatoscópico vem sendo uma ferramenta útil na presunção do diagnóstico. Descrevemos um caso com um padrão morfológico em que a lesão é confluente, sendo denominado líquen aureus agminado.

ABSTRACT

Desmoplastic melanoma tends to present as firm, amelanotic papules. Microscopically, it reveals a proliferation of fusiform cells in the dermis and variable collagen deposition, as well as intraepidermal melanocytic proliferation of lentiginous type in most cases. Biopsy in a 61-year-old white male patient, who had received a diagnosis of lentigo maligna on his face 10 years before, revealed a proliferation of dermal pigmented spindle cells and collagen deposition, reaching the deep reticular dermis, with a lentiginous component. Immunohistochemistry with S-100, Melan-A and WT1 showed positivity, but it was weak with HMB45. Desmoplastic melanoma associated with lentigo maligna was diagnosed. Several authors discuss whether desmoplastic melanoma represents a progression from the lentiginous component or arises "de novo". Desmoplastic melanoma represents a minority of cases of primary cutaneous melanoma (less than 4%). Identification of lentigo maligna indicates that desmoplastic melanoma should be carefully investigated.


Os melanomas desmoplásicos apresentam-se como pápulas amelanóticas firmes; à microscopia exibem proliferação de células fusiformes na derme e variável deposição de colágeno, além de proliferação melanocítica lentiginosa, intraepidérmica, na maioria dos casos. Realizada biópsia de pele de paciente masculino, 61 anos, branco, com diagnóstico de lentigo maligno na face, há 10 anos. O exame histopatológico revela proliferação dérmica de células fusiformes pigmentadas e deposição de colágeno, invadindo até a profundidade da derme reticular, associado a componente lentiginoso; presença de positividade imuno-histoquímica com S-100, Melan-A e WT1, e marcação fraca com HMB45. Diagnóstico de melanoma desmoplásico, associado a lentigo maligno. Existe divergência quanto à origem do melanoma desmoplásico, a partir do componente lentiginoso ou "de novo", na ausência de lentigo associado. O melanoma desmoplásico representa uma minoria dos casos de melanoma cutâneo primário (menos de 4%). A presença de lentigo maligno pode servir de sinal de alerta para possível relação com melanoma desmoplásico.

ABSTRACT

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. The possible implications of such proposition in cases of discoid lupus erythematosus and other scalp disorders are also discussed.


Pontos vermelhos foliculares foram descritos como achado tricoscópico de lupus eritematoso discóide do couro cabeludo em atividade e a presença destes associado a melhor prognóstico. Relatamos cinco pacientes com distúrbios da pigmentação nos quais pontos vermelhos foliculares foram detectados ao exame do couro cabeludo. Sugerimos que este padrão está provavelmente relacionado à rica vascularização que naturalmente envolve o folículo piloso normal. As possíveis implicações desta suposição nos casos de lupus eritematoso discóide e outras doenças do couro cabeludo também são discutidas.

ABSTRACT

BACKGROUND: Dysplastic nevi are among the most important cutaneous melanoma simulators. They are important risk markers for this neoplasia and can be its potential precursors. Some authors found a statistically significant relationship between the degree of dysplasia and the risk for developing melanoma. However, reproducibility of grading criteria ranged from poor to fair in the researched articles. OBJECTIVE: To test the reproducibility of the grading criteria proposed by Sagebiel et al. regarding dysplastic nevi. METHODS: Histological specimens of 75 dysplastic nevi were graded, independently and in a blinded fashion, according to preestablished criteria, by a panel of 10 pathologists with different levels of experience. Diagnostic agreement was calculated using weighted kappa and intraclass correlation coefficients. RESULTS: The average of weighted kappa values was 0.13 for all observers, 0.12 for dermatopathologists, 0.18 for general pathologists and 0.05 for residents. Intraclass correlation coefficient values were 0.2 for all observers, 0.18 for dermatopathologists, 0.33 for general pathologists and 0.15 for residents. CONCLUSIONS: Histopathological grading for dysplastic nevi was not reproducible in this Brazilian series, so the criteria used are not a helpful histopathological parameter for clinicopathological correlation. .


FUNDAMENTOS: Nevos displásicos estão entre os mais importantes simuladores de melanoma. São marcadores de risco para o desenvolvimento dessa neoplasia e podem ser seus precursores. Alguns autores observaram uma relação estatisticamente significativa entre o grau de displasia e o risco de desenvolvimento de melanoma. No entanto, a reprodutibilidade dos critérios para graduação variou de ruim a razoável nos artigos consultados. OBJETIVO: Testar a reprodutibilidade da graduação proposta por Sagebiel et al. para os nevos displásicos. MÉTODOS: Seções histológicas de setenta e cinco nevos displásicos foram graduadas, de forma independente e anônima, segundo critérios pré-estabelecidos, por um painel de 10 patologistas com diferentes níveis de experiência. A concordância diagnóstica foi calculada usando os coeficientes de kappa ponderado e de correlação intraclasse. RESULTADOS: A média dos valores de kappa ponderado foi de 0,13 para todos os observadores, de 0,12 para os dermatopatologistas, de 0,18 para os patologistas gerais e de 0,05 para os residentes. Os valores dos coeficientes de correlação intraclasse foram 0,2 para todos os observadores, 0,18 para os dermatopatologistas, 0,33 para os patologistas gerais e 0,15 para os residentes. CONCLUSÕES: A graduação histopatológica dos nevos displásicos não foi reprodutível nesta ...

ABSTRACT

Two cases of relapse in borderline leprosy were reported. Despite the late-reversal, reaction-like feature, the suspicion of relapse in both was based on persistent and slow-developing skin lesions and an absence of acute neuritis or reaction during one year of follow-up. The authors have considered this possible occurrence in lepromatous borderline-treated patients after their immune cellular restoration and defend that not all Type 1 reactions would be an inflammatory answer to persistent Mycobacterium leprae, but that they could be. Therefore, a relapse diagnosis could be applied and it is more advisable, as one year of Multi-Drug Therapy (MDT) is less dangerous and more efficient for these cases than one year of corticosteroids.


São apresentados dois casos de recidiva de hanseníase borderline. Apesar das características de reação reversa tardia, a suspeita de recidiva foi baseada no desenvolvimento insidioso e persistente de lesões cutâneas sem reação e neurite agudas, durante um ano de seguimento. Os autores consideram a possibilidade de recidiva em pacientes borderline virchowinano tratados, pela restauração da imunidade celular e postulam que embora nem toda reação tipo 1 seja devida a presença de M. leprae persistentes, isso também pode ocorrer. Assim, o diagnóstico de recidiva foi considerado ressaltando-se que um ano de poliquimioterapia oferece menos danos e pode ser mais eficiente nesses casos, que um ano de corticosteróides.

ABSTRACT

O nevo de Reed ou nevo de células fusiformes pigmentado pode ser um simulador do melanoma cutâneo. Apresenta, entretanto, diferentes características dermatoscópicas e histopatológicas. Trata-se de relato de três pacientes com apresentações clínicas, dermatoscópicas e histopatológicas distintas, correlacionando-as no auxílio diagnóstico deste com o melanoma e nevo de Sptiz.


Reed nevus or pigmented spindle-cell nevus may mimic cutaneous melanoma; however, its dermoscopic and histopathological characteristics are different. This case report describes three patients with distinct clinical, dermoscopic and histopathological presentations, which were correlated to enable a differential diagnosis to be made between melanoma and Spitz nevus.

ABSTRACT

O melanoma cutâneo é um problema de saúde pública a nível mundial. Sua incidência tem aumentado, de forma marcante, nos últimos anos, e o diagnóstico e excisão precoces são essenciais para o bom prognóstico dos pacientes. Neste contexto, a dermatoscopia ganhou grande importância, nas últimas duas décadas, melhorando, de forma significativa, a acurácia do diagnóstico do melanoma, em estágios iniciais. Porém, existem algumas lesões benignas que apresentam dermatoscopia duvidosa, levando à realização de cirurgias desnecessárias. Mais recentemente, a microscopia confocal reflectante vem sendo introduzida como método diagnóstico auxiliar promissor, por ser um exame não-invasivo, realizado in vivo, de forma simples, indolor e de rápida execução. É a única técnica capaz de identificar estruturas celulares e examinar a epiderme e a derme papilar, com resolução semelhante à da histopatologia, com uma sensibilidade de 97,3 por cento, e especificidade de 72,3 por cento para o diagnóstico do melanoma cutâneo. É uma importante ferramenta diagnóstica, visto que não substitui o exame histopatológico realizado no pós-operatório, mas permite a abordagem racional das lesões com dermatoscopia duvidosa, evitando procedimentos cirúrgicos desnecessários.


Skin melanoma is an international public health issue, with a considerable increase in frequency over the past few years. Early diagnosis and excision are essential for good patient prognosis. Over the past two decades dermoscopy has gained significance due to a major improvement in the accuracy of skin melanoma diagnosis in its early stage. However, there are some benign lesions of questionable dermoscopy, which may lead to the performance of unnecessary surgery. Recently, reflectance confocal microscopy has been introduced as a promising supplementary diagnostic method. It is a noninvasive, in vivo, simple, painless and quick exam. It is the only technique capable of identifying cellular structures and to examine the epidermis and papillary dermis with a resolution similar to that of histopathology, with a sensitivity of 97.3 percent and specificity of 72.3 percent in the diagnosis of cutaneous melanoma. This is an important diagnostic tool, because it does not substitute post-surgical histopathological examination and allows for the rational assessment of lesions of questionable dermoscopy, thus avoiding unnecessary surgical procedures.

ABSTRACT

Melanoníquia, do grego mélaina, negro, sombrio, resulta de uma deposição aumentada de melanina na lâmina ungueal originada a partir da matriz ungueal. Apresenta diversas causas, entre elas, o melanoma subungueal, por isso, seu diagnóstico etiológico torna-se essencial, devendo ser o mais precoce possível. Os autores apresentam dois pacientes com melanoníquias de natureza distinta e enfatizam o seu diagnóstico diferencial.


Melanonychia, from the Greek mélaina, means black and is the result of an increased deposition of melanin on the nail plate, originating in the nail matrix. It may have different causes, including subungueal melanoma, making early etiologic diagnosis very important.

ABSTRACT

A úlcera hipertensiva de Martorell é úlcera isquêmica dolorosa de membro inferior, mais comum em mulheres, com dor desproporcional a seu tamanho e associada à hipertensão arterial sistêmica grave. É descrito um caso de homem negro, 56 anos, com hipertensão mal controlada de longa duração e lesão ulcerada extensa na panturrilha direita, cuja dor só foi aliviada com morfina, bloqueios peridurais e simpatectomia lombar. O diagnóstico baseou-se em hipertensão arterial, pulsos arteriais palpáveis, ausência de distúrbios venosos e dor intensa. O exame histopatológico de pele revelou alterações características, como espessamento da camada íntima da arteríola e estreitamento da luz.


Martorell's hypertensive ulcer is a painful lower extremity ischemic ulcer, with female-to-male predominance and associated to severe systemic arterial hypertension. We describe a case of a 56 years-old black man with long standing and poorly controlled arterial hypertension who presented a large ulcer on the right calf, whose pain was improved with morphine, peridural blockages and lumbar sympathectomy. The diagnosis was based on systemic arterial hypertension, palpable arterial pulses of lower extremities, absence of venous insufficiency and presence of intense pain. Cutaneous histopathology revealed characteristic lesions in the arterioles, such as thickening of intimal layer and narrowing of the lumen.

ABSTRACT

A análise de 40 casos de pênfigo estudados com exame histopatológico e de imunofluorescência direta e indireta no Hospital Universitário da Universidade Federal do Rio de Janeiro revelou que o pênfigo foliáceo é ligeiramente mais freqüente que o pênfigo vulgar na populaçäo atendida neste centro médico. A detecçäo de auto-anticorpos circulantes através da imunofluorescência indireta nem sempre é possível, principalmente nos pacientes com pênfigo foliáceo. Contudo, a imunofluorescência direta é exame altamente sensível para a confirmaçäo do diagnóstico da doença, embora näo se preste para a diferenciaçäo entre suas principais formas com precisäo. A subtipagem do pênfigo deve obedecer critérios clínicos e histopatológicos. A concomitância de deposiçäo de IgG e C na substancia intercelular da epiderme e na junçäo dermo-epidérmica é um achado laboratorial ocasional que pode ocorrer em qualquer das formas clínicas da doença
