Abstract Cutaneous neoplasms frequently occur in leprosy, but there are few reports of the coexistence of leprosy and basal cell carcinoma in the same lesion. This case reports a 49-year-old male with an ulcerated plaque on the right lateral nasal wall, bright papules on the sternal region, and a blackened plaque on the right temporal region. The nasal and temporal lesions were diagnosed by histopathology as basal cell carcinoma and melanoma, respectively. The sternal lesions were excised with the repair of the “dog ear” which histopathological examination showed macrophages in the dermis parasitized with acid-fast bacilli, confirming the diagnosis of lepromatous leprosy with Fite-Faraco staining. This case report highlights the importance of referring the dog-ear specimen for histopathologic analysis.

Abstract: Background: Erythema nodosum leprosum may appear before, during or after treatment of leprosy and is one of the main factors for nerve damage in patients. When it occurs or continues to occur after treatment, it may indicate disease recurrence and a new treatment may be instituted again. Objective: To evaluate the retreatment of patients with multibacillary leprosy who underwent standard treatment with multidrug therapy, but developed or continued to present reactions of erythema nodosum leprosum and/or neuritis 3-5 years after its end. Method: For this objective, a new treatment was performed in 29 patients with multibacillary leprosy who maintained episodes of erythema nodosum and/or neuritis 3-5 years after conventional treatment. Results: In general, we observed that 27 (93.10%) had no more new episodes after a follow up period of eight months to five years. In five of these patients the reason for the retreatment was the occurrence of difficult-to-control neuritis, and that has ceased to occur in all of them. Study limitations: Small number of patients.. Conclusion: In the cases observed, retreatment was an effective measure to prevent the occurrence of erythema nodosum leprosum and/or persistent neuritis.

Resumo: O estudo teve como objetivos identificar o padrão de distribuição da hanseníase em um município brasileiro hiperendêmico e determinar a relação com o quadro clínico-epidemiológico ao longo de 11 anos. Os casos novos foram analisados com o sistema de informação geográfica, MapInfo, estatística scan espacial e índice Moran I. A base cartográfica digital foi usada para mapear os clusters de casos paucibacilares e multibacilares novos e casos em menores de 15 anos. Os indicadores socioeconômicos são mostrados através da técnica de mapeamento coroplético. Entre 2006 e 2010, foram observados uma redução no coeficiente de detecção, aumento no clusters espaciais de alto risco, mudanças marcantes na distribuição de clusters de alto e baixo risco e clusters de alto risco em menores de 15 anos, sugerindo doença recente, a presença de focos ativos e a sobreposição de clusters de alto risco para infecção multibacilar em menores de 15 anos. A hanseníase persiste enquanto problema de saúde pública em Rondonópolis, Mato Grosso; as áreas de alto risco exigem a intensificação de medidas de controle, além de estratégias de busca ativa para detectar casos novos.

Abstract: This study aimed to identify the distribution pattern of leprosy in a hyperendemic municipality in Brazil and determine its relationship with the clinico-epidemiological situation over 11 years. The geographic information system, MapInfo, spatial scan statistics and the Moran I index were used to analyze new cases. The digital cartographic base was used to map clusters of new paucibacillary and multibacillary cases and cases in minors under 15 years old. Socioeconomic indicators are shown using the choropleth mapping technique. A reduction in the detection coefficient, increases in high-risk spatial clusters, marked changes in the distribution of high-risk and low-risk clusters, and high-risk clusters of minors under 15 years old were observed from 2006 to 2010, showing recent illness, the presence of active foci, and overlapping of high-risk clusters of multibacillary infection in minors under 15 years old. Leprosy remains a public health problem in Rondonópolis, Mato Grosso State; the high-risk areas require an intensification of control measures and active search strategies to detect new cases.

Abstract Clinical presentation of paracoccidioidomycosis (PCM) can be diverse. Morphology and quantity of skin lesions depends on interactions between host immunity and fungus virulence. Diagnosis can be a challenge considering that this fungus has low virulence and some individuals have immunity to microorganism, which results in well-marked granulomas without visible microorganisms. We report herein a clinical presentation of sarcoid-like PCM, initially diagnosed as tuberculoid leprosy. This rare type of PCM is often mistaken for other types of chronic granulomatous diseases. Diagnosis was confirmed after 4 years when a special stain analysis helped in the identification of the specific etiologic agent.

Abstract: The authors report aspects of paracoccidioidomycosis, acute-subacute clinical form, juvenile type, in a 19-year-old female patient. Paracoccidioidomycosis, juvenile type, classically occurs in young patients, both sexes, with lymphoma-like aspects as initial presentation. However, following the natural history of the disease the lymph nodes assume patterns of infectious disease, as an abscess and fistulae. Systemic dissemination of the disease can occur and lethality and morbidity are significant in this clinical presentation.

Abstract: The Brazilian Society of Dermatology promoted a national campaign against leprosy in 2012, involving their State Regional, Accredited Services of Dermatology and Referral Services in Leprosy. Consisted of clarification to the population about the disease and a day of medical voluntary service. Ninety services (57 Accredited Services and 33 Reference Services) participated, distributed in 23 states. The campaign examined 3,223 people and 421 new cases were diagnosed, 54,4% female, 74,3% between 19 and 64 years and 8,3% in children under 15 years. Of the 217 classified cases, 58,5% was paucibacillary and 41,5% was multibacillary. The results were posted on the Brazilian Society of Dermatology website.

Leprosy is a chronic infectious condition caused by Mycobacterium leprae(M. leprae). It is endemic in many regions of the world and a public health problem in Brazil. Additionally, it presents a wide spectrum of clinical manifestations, which are dependent on the interaction between M. leprae and host, and are related to the degree of immunity to the bacillus. The diagnosis of this disease is a clinical one. However, in some situations laboratory exams are necessary to confirm the diagnosis of leprosy or classify its clinical form. This article aims to update dermatologists on leprosy, through a review of complementary laboratory techniques that can be employed for the diagnosis of leprosy, including Mitsuda intradermal reaction, skin smear microscopy, histopathology, serology, immunohistochemistry, polymerase chain reaction, imaging tests, electromyography, and blood tests. It also aims to explain standard multidrug therapy regimens, the treatment of reactions and resistant cases, immunotherapy with bacillus Calmette-Guérin (BCG) vaccine and chemoprophylaxis.

Leprosy is caused by Mycobacterium leprae and has been known since biblical times. It is still endemic in many regions of the world and a public health problem in Brazil. The prevalence rate in 2011 reached 1.54 cases per 10,000 inhabitants in Brazil. The mechanism of transmission of leprosy consists of prolonged close contact between susceptible and genetically predisposed individuals and untreated multibacillary patients. Transmission occurs through inhalation of bacilli present in upper airway secretion. The nasal mucosa is the main entry or exit route of M. leprae. The deeper understanding of the structural and biological characteristics of M. leprae, the sequencing of its genome, along with the advances in understanding the mechanisms of host immune response against the bacilli, dependent on genetic susceptibility, have contributed to the understanding of the pathogenesis, variations in the clinical characteristics, and progression of the disease. This article aims to update dermatologist on epidemiological, clinical, and etiopathogenic leprosy aspects.

BACKGROUND: Leprosy can have its course interrupted by type 1 and 2 reactional episodes, the last named of erythema nodosum leprosum (ENL). Thalidomide has been the medication of choice for the control of ENL episodes since 1965. OBJECTIVES: These episodes can repeat and cause damages to the patient. In order to prevent these episodes, an extra dose of 100 mg/day thalidomide was used during six months, followed by a follow-up period of six more months after thalidomide discontinuation. METHODS: We included 42 patients with multibacillary (MB) leprosy who had episodes of ENL. They were male and female patients aged between 18 and 84 years. RESULTS: Of the 42 patients, 39 (92.85%) had the lepromatous form and three (7.15%) had the borderline form. We found that 100% of patients had no reactional episode during the use of the drug. During the follow-up period after thalidomide discontinuation, 33 (78.57%) patients had no reactional episode and nine (21.43%), all of them with the lepromatous form, had mild episodes, which were controlled using non-steroidal anti-inflammatory. There were no thalidomide-related side effects. CONCLUSION: A maintenance dose of 100 mg/day of thalidomide showed to be effective to prevent repeated type 2 reactional episodes of ENL.

Leprosy is a chronic infectious disease caused by Mycobacterium leprae, a microorganism that usually affects skin and nerves. Although it is usually well-controlled by multidrug therapy (MDT), the disease may be aggravated by acute inflammatory reaction episodes that cause permanent tissue damage particularly to peripheral nerves. Tuberculosis is predominantly a disease of the lungs; however, it may spread to other organs and cause an extrapulmonary infection. Both mycobacterial infections are endemic in developing countries including Brazil, and cases of coinfection have been reported in the last decade. Nevertheless, simultaneous occurrence of perianal cutaneous tuberculosis and erythema nodosum leprosum is very rare, even in countries where both mycobacterial infections are endemic.

FUNDAMENTOS: A Sociedade Brasileira de Dermatologia Regional do Estado de São Paulo (SBD-RESP), apoiada pela Fundação Paulista Contra a Hanseníase, e em ação conjunta com os Serviços de Dermatologia do estado de São Paulo, credenciados pela Sociedade Brasileira de Dermatologia, lançou a campanha "SBD-RESP na Busca Ativa de Casos de Hanseníase". OBJETIVOS: Auxiliar o Programa Nacional de Controle da Hanseníase no controle da doença. MÉTODO: Todos os Serviços de Dermatologia do estado de São Paulo, credenciados pela Sociedade Brasileira de Dermatologia, foram convidados e os 17 que participaram receberam uma planilha de dados e modelos de materiais informativos sobre a doença. A campanha foi realizada entre os meses de maio e julho de 2010. Ao término do período, cada serviço encaminhou a planilha de dados para análise estatística. RESULTADOS: Foram examinadas 1718 pessoas e diagnosticados, no total, 90 casos de hanseníase, a maioria do gênero masculino e da cor branca, com percentuais semelhantes de multibacilares e de paucibacilares. Doze por cento apresentavam história familiar de hanseníase. O maior número de casos detectados foi na capital, seguido, no interior, pela região de Presidente Prudente. O índice de detecção em menores de 15 anos foi 4%. CONCLUSÕES: Os resultados da campanha mostram a importância desta iniciativa da SBD-RESP. Sugere-se que ações semelhantes sejam repetidas e que se estendam a outras regionais da Sociedade Brasileira de Dermatologia

BACKGROUND: The Brazilian Society of Dermatology of the State of Sao Paulo (SBD-RESP), supported by the Sao Paulo State Foundation Against Leprosy and acting jointly with Sao Paulo State Services of Dermatology, accredited by the Brazilian Society of Dermatology, launched the campaign "SBD-RESP in active search for leprosy cases". OBJECTIVES: To assist the National Leprosy Control Program in eliminating Hansen's disease. METHODS: All of the Sao Paulo State Services of Dermatology, accredited by the Brazilian Society of Dermatology, were invited to join the campaign. The 17 Services which accepted to participate received a spreadsheet of data and models of informative materials about the disease. The campaign lasted from May to July 2010. At the end of the campaign, each Service sent the spreadsheet data for statistical analysis. RESULTS: 1,718 people were examined and 90 cases of Hansen's disease were diagnosed. Most of the individuals infected were male and white and presented similar percentages of multibacillary and paucibacillary groups. Twelve percent had a family history of leprosy. The highest number of cases was detected in Sao Paulo city, followed by the region of Presidente Prudente, located in the countryside of Sao Paulo State. The detection rate in children younger than 15 years old was 4%. CONCLUSION: The campaign results show the importance of the SBD-RESP initiative. It is suggested that similar actions be repeated and extended to other regional offices of the Brazilian Society of Dermatology

Os autores relatam caso de paciente do sexo feminino com paracoccidioidomicose, associada a carcinoma do colo uterino estádio IIIB. Paracoccidioidomicose, associada à neoplasia, ocorre entre 0,16% a 14,1% segundo diferentes séries de casos. Em casos com neoplasia disseminada a infecção fúngicas pode apresentar comportamento oportunístico

This report describes the case of a female patient with paracoccidioidomycosis associated with a stage IIIB cervical carcinoma. Paracoccidioidomycosis in association with a malignant tumor occurs in 0.16% to 14.1% of cases in accordance with different case series. In cases in which the cancer is disseminated, the fungal infection may behave opportunistically

Os Autores relatam um caso de paracoccidioidomicose diagnosticado como se fora hanseníase tuberculóide, tanto do ponto de vista clínico como histopatológico. Lesão cutânea de padrão sarcoídico é raramente observada como lesão inicial da paracoccidioidomicose em jovens e pode simular outras dermatoses infecciosas ou inflamatórias. O achado histológico de granuloma tuberculóide apresenta dificuldade diagnóstica similar. O tratamento realizado com dapsone, um derivado sulfamídico, pode ter retardado a evolução clínica esperada para o padrão clássico da paracoccidioidomicose tipo juvenil, o qual apenas se materializou 24 meses após a paciente ter iniciado tratamento como hanseníase.

The authors report a case of paracoccidioidomycosis misinterpreted as tuberculoid leprosy, both on clinical and histological examination. Sarcoid-like cutaneous lesion as the initial presentation is rare in young patient with paracoccidioidomycosis and can simulate other infectious or inflammatory diseases. On histology, tuberculoid granuloma presented similar difficulties. Treatment with dapsone, a sulfonamide derivative, could have delayed the presumed natural clinical course to the classical juvenile type of paracoccidioidomycosis, observed only 24 months after the patient had been treated for leprosy.
