Angiomatosis bacilar y micobacteriosis atípica en paciente con diagnóstico reciente de infección por el virus de la inmunodeficiencia humana / Bacillary Angiomatosis and Atypical Mycobacteriosis in a patient recently diagnosed with Human Immunodeficiency Virus infection

Múltiples infecciones oportunistas pueden manifestarse simultáneamente cuando la inmunosupresión es grave en pacientes infectados por el virus de la inmunodeficiencia humana. Se presenta un caso de coinfección de VIH, Bartonella spp y Mycobacterium kansasii, siendo escasos los reportes a la fecha de dicha asociación y aun más en pacientes que desconocen su condición de VIH

Multiple opportunistic infections can manifest simultaneously when immunosuppression is severe in patients infected with the human immunodeficiency virus. A case of co-infection with HIV, Bartonella spp and Mycobacterium kansasii is presented, with few reports to date of this association and even more so in patients who are unaware of their HIV status.

Aortic valve endocarditis due to Bartonella clarridgeiae in a dog in Brazil / Endocardite de válvula aórtica por Bartonella clarridgeiae em um cão no Brasil

Abstract We report the first documented case of endocarditis associated with Bartonella clarridgeiae in a dog in Latin America. Infective vegetative valvular aortic endocarditis was diagnosed in a 10-year-old male mixed breed dog. The dog presented grade V/VI systolic and diastolic murmur, hyperthermia, and progressive weight loss. Cardiomegaly and presence of diffuse alveolar pattern in the lung fields were observed in the thorax radiography evaluation. Irregular and hyperechogenic structures adhered to the aortic leaflets, causing obstruction of the left ventricular outflow tract and severe aortic insufficiency, were observed in the echocardiography evaluation. A vegetative, whitish, hardened structure measuring 1.0 cm in diameter was observed in aortic semilunar valve at necropsy. Based on a combination of pre-enrichment insect-based medium liquid culture, quantitative real-time and conventional PCR assays based on nuoG and gltA genes, respectively, followed by sequencing and phylogenetic inferences, B. clarridgeiae DNA was detected in the patient's aortic valve lesions. Clinical, echocardiographic, anatomopathologic and molecular features supported the diagnosis of severe aortic vegetative endocarditis possibly caused by B. clarridgeiae in a dog in Brazil.

Resumo Relatamos o primeiro caso documentado de endocardite associada à Bartonella clarridgeiae em um cão na América Latina. Endocardite aórtica valvar vegetativa infecciosa foi diagnosticada em um cão sem raça definida de 10 anos de idade. O cão apresentou sopro sistólico e diastólico de grau V / VI, hipertermia e perda progressiva de peso. Cardiomegalia e presença de padrão alveolar difuso nos campos pulmonares foram observados na avaliação radiográfica do tórax. Estruturas irregulares e hiperecogênicas aderidas aos folhetos aórticos, causando obstrução da via de saída do ventrículo esquerdo e insuficiência aórtica grave, foram observadas na avaliação ecocardiográfica. À necropsia, foi observada uma estrutura vegetativa, esbranquiçada e endurecida medindo 1,0 cm de diâmetro na válvula semilunar aórtica. Por meio de uma combinação de cultura líquida baseada em meio de pré-enriquecimento de inseto, ensaios de PCR quantitativa em tempo real e convencional baseados nos genes nuoG e gltA, respectivamente, seguidos de sequenciamento e inferências filogenéticas, DNA de B. clarridgeiae foi detectado no tecido valvular lesionado do paciente. O diagnóstico de endocardite vegetativa aórtica grave, possivelmente causado por B. clarridgeiae em um cão no Brasil, foi apoiado por características clínicas, ecocardiográficas, anatomopatológicas e moleculares.

Cutaneous manifestations of bartonellosis

Abstract Bartonellosis are diseases caused by any kind of Bartonella species. The infection manifests as asymptomatic bacteremia to potentially fatal disorders. Many species are pathogenic to humans, but three are responsible for most clinical symptoms: Bartonella bacilliformis, Bartonella quintana, and Bartonella henselae. Peruvian wart, caused by B. bacilliformis, may be indistinguishable from bacillary angiomatosis caused by the other two species. Other cutaneous manifestations include maculo-papular rash in trench fever, papules or nodules in cat scratch disease, and vasculitis (often associated with endocarditis). In addition, febrile morbilliform rash, purpura, urticaria, erythema nodosum, erythema multiforme, erythema marginatus, granuloma annularis, leukocytoclastic vasculitis, granulomatous reactions, and angioproliferative reactions may occur. Considering the broad spectrum of infection and the potential complications associated with Bartonella spp., the infection should be considered by physicians more frequently among the differential diagnoses of idiopathic conditions. Health professionals and researchers often neglected this diseases.

Experiencias en la prevención y control de la enfermedad de Carrión en el Perú / Experiences in the prevention and control of Carrión's disease in Peru

La enfermedad de Carrión, enfermedad emblemática de la medicina peruana, ha sido descrita en la sierra de Ecuador, Colombia y valles interandinos del Perú. En la década de 1990, el fenómeno de El Niño fue asociado con incremento significativo del riesgo de enfermedad en Ancash, Cajamarca y Cusco. Justamente en Cusco en 1998 se produjo una importante epidemia de la fase aguda en diversas provincias andinas y la zona selvática. Posteriormente entre 2001 y 2005 la enfermedad se ha expandido o reactivado en diversas regiones como Ancash, Cajamarca, Amazonas, Piura, Cusco, La Libertad, Puno, Ayacucho. El 2004 se presentó un rebrote importante de la enfermedad en todo el Perú, reportándose más de 11 164 casos, por ello se aplicaron diversas estrategias de control basados en estudios de susceptibilidad de vectores, disminuyendo en forma significativa el número de casos.

Carrion’s disease, the iconic disease in Peruvian medicine has been found in the mountains of Ecuador, Colombia and the Andean valleys of Peru. In the 1990s, the phenomenon of El Niño was associated with significantly increased risk of disease in Ancash, Cajamarca and Cusco. In Cusco in 1998 there was an acute phase epidemic in various Andean provinces and the jungle area. Between 2001 and 2005 the disease has spread or reactivated in different regions such as Ancash, Cajamarca, Amazonas, Piura, Cusco, La Libertad, Puno, and Ayacucho. In 2004 a major outbreak of the disease in all of Peru was presented, reporting more than 11 164 cases, and therefore diverse strategies based vector susceptibility studies was applied, lowering significantly the number of cases.

Soroprevalência de Bartonella sp., Coxiella burnetii e Hantavirus em Pessoas que Injetam Drogas Ilícitas no Estado do Rio de Janeiro nos anos de 1999 a 2001 / Seroprevalence of bartonella sp., coxiella burnetti and hantavirus in intravenous illicit drug users in the state of Rio de Janeiro in the years of 1999-2001

O aumento do consumo de drogas ilícitas na atualidade vem acompanhado não apenas do impacto social e econômico, como também na saúde. As pessoas que injetam drogas apresentam maior susceptibilidade a infecções por diversos agentes, devido ao uso da droga e à subsequente imunossupressão, como também pelo risco de maior exposição a agentes transmitidos por artrópodes e reservatórios vertebrados em ambientes insalubres. São muitos os estudos correlacionando o consumo de drogas à infecção pelo HIV, VHB e VHC, porém raros investigam outros agentes. No presente estudo transversal e retrospectivo, selecionamos aleatoriamente 300 amostras de um estudo multicêntrico da década de 1990 e fizemos a pesquisa sorológica para Bartonella spp., Coxiella burnetii e Hantavirus. O perfil demográfico e social encontrado mostrou-se em concordância com a literatura: homens, jovens, de baixa renda e com histórico de prisão. A maior parte apresentava situações de risco por injetar drogas com dispositivos previamente usados e por injetar em local público. Alguns fatores foram discordantes da literatura internacional e podem ter influenciado os resultados, uma vez que são considerados situações de risco, como escassez de pessoas que injetaram drogas enquanto presas, que residem em instituições, ou sem-tetoA evidência de infecção por C. burnetii foi de 9,3 porcento, praticamente o dobro da observada na população geral brasileira, embora, em comparação com dados internacionais, a prevalência tenha sido menor. Não houve diferença estatística significativa em relação às variáveis demográficas entre os grupos sororeativos e soronegativos para febre Q. A presença de anticorpos anti-Bartonella foi de 1 porcento, bem discrepante dos estudos nacionais e internacionais. Pode ser justificado pela não inclusão no teste sorológico de antígeno de B. elizabethae e de B. quintana e pela reduzida frequência de sem-tetos...

The increased consumption of illicit drugs today is followed not only by a social and economic impact, as well as in health. People who inject drugs are more susceptible to infections by various agents due to drug use and subsequent immunosuppression, as well as the risk of increased exposure to agents transmitted by arthropods and vertebrate reservoirs in unhealthy environments. Many studies link drug use to HIV, HBV and HCV,however only a few investigate other agents. In this retrospective cross-sectional study, we selected randomly 300 samples from a multicenter study from the 1990s and made aserological survey for Bartonella spp., Coxiella burnetii and hantavirus. The demographic and social profile was found in agreement with the literature: men, young age, low incomeand with a history of imprisonment. The majority was exposed to risk situations by injecting drugs with previously used devices and by injecting in a public places. Some factors were disagreeing with the international literature and may have influenced theresults, since they are considered high-risk situations, such as shortage of people whoinjected drugs while imprisoned, residing in institutions, or homeless. Evidence of C.burnetii infection was 9.3 percent, almost double the rate in the general Brazilian population,although in comparison with international data, the prevalence was lower. There was nostatistically significant difference in relation to demographic variables among seroreactiveand seronegative groups for fever Q. The presence of antibodies to Bartonella was 1percent, significantly discrepant from national/international studies. Possibly justified by the noninclusion of antigen B. elizabethae and B. quintana in the serological test, and the reduced frequency of homelessness. There was no correlation between high alcohol consumption with higher seroprevalence of Bartonella spp., probably for the reasons mentioned above...

Aspectos clínicos, epidemiológicos e laboratoriais das bartoneloses em crianças do Rio de Janeiro / Clinical, epidemiological and laboratory aspects of bartonellosis in children in Rio de Janeiro

As bartoneloses são doenças mundialmente dispersas causadas por bactérias gramnegativas do gênero Bartonella. Com mais de 24 espécies reconhecidas, B. bacilliformis, B.henselae e B. quintana são os principais e mais comuns agentes causadores de doença emhumanos. Na literatura existem relatos de casos isolados e alguns estudos de prevalênciasorológica sobre a doença, a maioria realizados em pacientes adultos, com escassainformação sobre a sua apresentação e a epidemiologia nas crianças. A proposta desseestudo retrospectivo foi analisar uma série casos de bartonelose em pacientes abaixo de 16anos, no estado do Rio de Janeiro, durante o período de 2006 a 2012, a partir dos dadossecundßrios obtidos no banco de dados do Laboratório de Referência Nacional paraRickettsioses, Laboratório de Hantavirose e Rickettsioses do Instituto Oswaldo Cruz, Rio deJaneiro. Dos 36 confirmados por anßlise sorológica utilizando teste de imunofluorescênciacomercial, com títulos de corte de 64, e/ ou por reação em cadeia da polimerase, 19 casos(52,7 por cento) foram do sexo feminino, com uma variação por faixa etßria de zero a 16 anos, 19(52,7 por cento) tinham entre 11 e 16 anos de idade. A maioria dos casos - 22 casos (61,1 por cento) -, foiprocedente do município do Rio de Janeiro, com mais cinco (13,8 por cento ) e três (8,3 por cento) empacientes residentes nos municípios de Duque de Caxias e Nova Iguaçu. A informaçãosobre contato com gato estava disponível em apenas sete (19,4 por cento)...

Bartonelloses are globally dispersed diseases caused by gram-negative bacteria fromBartonella genus. With over 24 recognized species, B. bacilliformis, B. henselae and B.Quintana are the main and most common disease-causing agents in humans. In theliterature, there are reports of isolated cases and some seroprevalence studies about thedisease, most performed in adult patients, with limited information about its presentation andepidemiology in children. The purpose of this retrospective study was to analyze a caseseries of bartonellosis in patients aged less than 16 years, in the State of Rio de Janeiro,during the period 2006-2012. We assessed secondary data from the National ReferenceLaboratory for Rickettsiosis, Laboratory of Hantaviroses and Rickettsioses of Oswaldo CruzInstitute, Rio de Janeiro. Nineteen cases (52,7 percent), from 36 confirmed by serological analysisusing commercial immunofluorescence test, with antibody cut off titers of 64 , and / orpolymerase chain reaction, were female, with an age variation from zero to 16 years old, 19(52.7 percent) were between 11 and 16 years old. Most of cases - 22 (61.1 percent) û were found in thecity of Rio de Janeiro, with another five (13.8 percent) and three (8.3 percent) in patients residing in thecities of Duque de Caxias and Nova Iguaçu. Information about contact with cats wasavailable in just seven (19,4 percent). Clinical manifestations observed in this study were similar tothose described in the literature, in which it was possible to identify cat scratch disease(CSD), fever of unknown origin, and hepatosplenic form...

Molecular characterisation of Bartonella species in cats from São Luís, state of Maranhão, north-eastern Brazil

Bartonella species are fastidious bacteria that predominantly infect mammalian erythrocytes and endothelial cells and cause long-lasting bacteraemia in their reservoir hosts. Reports that describe the epidemiology of bartonellosis in Brazil are limited. This study aimed to detect and characterise Bartonella spp DNA from cat blood samples in São Luís, Maranhão, north-eastern Brazil. Among 200 cats tested for multiple genes, nine (4.5%) were positive for Bartonella spp: six cats for Bartonella henselae and three for Bartonella clarridgeiae. Based on the phylogenetic analysis of four genes, the B. henselae strain matched strains previously observed in Brazil and was positioned in the same clade as B. henselae isolates from the United States of America. Moreover, sequence alignment demonstrated that the B. clarridgeiae strain detected in the present study was the same as the one recently detected in cats from southern Brazil.

Febre do viajante associada com adenite cervical e sororreatividade para Bartonella sp em paciente brasileira, após retorno da África do Sul / Traveler's fever associated with cervical adenomegaly and antibodies for Bartonella sp in a Brazilian patient returning from South Africa

Um grande número de viajantes visita anualmente, por estudo, turismo ou trabalho o continente africano. Um caso de adenomegalia cervical e hepatoesplenomegalia associado à febre de duas semanas de duração com teste sorológico positivo para Bartonella sp em uma paciente de 22 anos do sexo feminino que retornou da África do Sul após realização de trabalho de campo com primatas em área silvestre é apresentado.

A large number of travelers visit the African continent annually for studying, tourism or business reasons. The authors report a case of cervical adenomegaly, hepatomegaly and splenomegaly associated with a two-week history of fever and seropositivity for Bartonella sp in a 22-year-old female patient who returned from South Africa after field work with primates in a wild area.

Bartonelose: análise molecular e sorológica em gatos do Rio de Janeiro Brasil / Bartonellosis: molecular and serological analysis in cats from Rio de Janeiro – Brazil

Bartonella henselae e mais recentemente B. quintana têm sido apontados como agentes causais de diversas moléstias emhumanos, entre as quais a doença da arranhadura do gato, endocardite, meningoencefalite e neuroretinite, podendo levarao óbito, principalmente os imunocomprometidos. O gato doméstico é considerado o principal animal envolvido na transmissãodestes patógenos. Constituiu-se objetivo deste estudo a avaliação da frequência de Bartonella spp. em gatos domésticosdomiciliados do município de Vassouras (RJ) comparando-se os achados na reação em cadeia pela polimerase (PCR) e nasorologia por imunofluorescência indireta (IFA). Amostras sanguíneas de 37 (100%) gatos de um abrigo da cidade deVassouras (RJ) foram analisadas, sendo 36 (97,3%) positivas na PCR para Bartonella spp. Das amostras PCR positivas,nove (25%) e 27 (75%) apresentaram, respectivamente, reatividade e ausência de reatividade ao IFA. Apenas uma (2,7%)amostra de sangue foi concomitantemente negativa na PCR e IFA para Bartonella spp. Este é o primeiro registro de infecçãopor Bartonella spp. em felinos domésticos no estado do Rio de Janeiro (Brasil) identificada por análise molecular e sorológica,o que nos permite concluir que este agente zoonótico está presente em alta frequência em gatos domésticos do municípiode Vassouras (RJ).

Bartonella henselae and B. quintana have been pointed as causal agents of many diseases in humans, and can lead to death, mainly immunodefficient people. Domestic cat is considered the unique animal in transmission of these pathogens. The purpose of this study was to evaluate the frequency of Bartonella spp. in domestic cats from Vassouras city (RJ) by polimerase chain reaction (PCR) and indirect immunofluorescence test assay (IFA) and compare the results. Blood samples from 37 (100%) domestic cats from a shelter of Vassouras city (RJ) were analyzed and 36 (97.3%) were considered positive by polymerase chain reaction (PCR). The indirect immunofluorescence test assay (IFA) revealed 9 (25.0%) and 27 (75.0%) of that PCR positive samples showed, respectively, reaction and absence of reaction to IFA. Only one sample (2.7%) was negative in PCR and IFA. This is the first communication of Bartonella spp. infection in domestic cats in Rio de Janeiro State (Brazil) identified by molecular and serological assays, thus it can be concluded that this zoonotic agent is present in high frequencies in domestic cats from Vassouras city (RJ).

Bartonella native valve endocarditis: the first brazilian case alive and well

Bartonella is an important cause of blood culture-negative endocarditis in recent studies. Seroprevalence studies in the States of Minas Gerais and Rio de Janeiro have shown Bartonella IgG positivity around 14 percent in healthy adults and 40 percent in HIV seropositive adults, respectively. A case report of a 46-year-old white male with moderate aortic regurgitation (AR) due to rheumatic heart disease (RHD), admitted due to worsening heart failure, is presented. Clinical features were apyrexia, anemia, polyclonal hypergammaglobulinemia, hematuria and splenomegaly. He was submitted to surgery due to worsening AR. Histopathology of the excised valve showed active bacterial endocarditis and underlying RHD. Routine blood cultures were negative. Indirect immunofluorescence (IFI) assays for Coxiella burnetii were non-reactive. Bartonella henselae IgG titer was 1:4096 prior to antibiotics and 1:512 14 months after treatment. History of close contact with a young cat during the months preceding his admission was elicited.

Angiomatosis bacilar: resolución espontánea? / Bacillary angiomatosis: spontaneous resolutión?

La angiomatosis bacilar es una enfermedad infecciosa oportunista con manifestaciones sistémicas, no conocidas antes de la epidemia del virus de la inmunodeficiencia humana (HIV). Se manifiesta usualmente en pacientes inmunodeprimidos con recuentos de linfocitos T CD4+ inferiores a 200 células /µL y su evolución, sin tratamiento, cuenta con elevados índices de mortalidad. Presentamos un paciente de sexo masculino, de 27 años, con antecedentes de SIDA, que había iniciado HAART 18 días antes de su derivación a nuestro servicio. Al examen físico se observaban lesiones generalizadas de 1 mes de evolución, compatibles clínica e histológicamente con angiomatosis bacilar, que resolvieron en forma espontánea en 4 semanas.

Bartonellosis: suggestive case reports in adult and pediatric patients and therapeutic issues

Cat-scratch disease warrants extensive investigation, from an epidemiological, a diagnostic, but especially a therapeutic point of view. Two suggestive episodes of Bartonella henselae-caused cat-scratch disease are reported, and discussed in the light of the most recent literature evidence. The first case occurred in a 60-year-old man, thus suggesting that it is important to maintain an elevated level of suspicion for this disease in adults as well. Both episodes were characterized by a very prolonged and complicated disease course (with the involvement of three lymph node sets in the first case), a need for lymph-node drainage, and apparently negligible activity of many antimicrobial courses, with a very slow local cure. While specific culture and molecular biology techniques proved negative (probably due to late availability of appropriate clinical specimens), indirect immunofluorescence antibody assay was positive since the first weeks of disease, and elevated levels were also fond many months after disease onset. When clinicians face patients with prominent swelling of lymph nodes draining from the upper limbs, cat-scratch disease may be suspected on the grounds of epidemiological and clinical features, with a limited systemic involvement contrasting with a prominent local disease. The significance of specific antibody temporal kinetics in the subacute disease course is still unknown. Although biomolecular assays are now available, the time elapsed from disease onset to clinical diagnosis usually hampers diagnosis, while the roles of surgical debridement and of the unpredictable activity of antimicrobial chemotherapy warrant careful investigation.

Se presentan los casos de 5 pacientes en los que los estudios por imágenes y la serología fueron de gran utilidad para su confirmación.

Bartonelosis (Carrion's Disease) in the pediatric population of Peru: an overview and update

Bartonellosis, or Carrion's Disease, is an endemic and reemerging disease in Peru and Ecuador. Carrion's Disease constitutes a health problem in Peru because its epidemiology has been changing, and it is affecting new areas between the highland and the jungle. During the latest outbreaks, and previously in endemic areas, the pediatric population has been the most commonly affected. In the pediatric population, the acute phase symptoms are fever, anorexia, malaise, nausea and/or vomiting. The main signs are pallor, hepatomegaly, lymphadenopathies, cardiac murmur, and jaundice. Arthralgias and weight loss have also commonly been described. The morbidity and mortality of the acute phase is variable, and it is due mainly to superimposed infections or associated respiratory, cardiovascular, neurological or gastrointestinal complications. The eruptive phase, also known as Peruvian Wart, is characterized by eruptive nodes (which commonly bleed) and arthralgias. The mortality of the eruptive phase is currently extremely low. The diagnosis is still based on blood culture and direct observation of the bacilli in a blood smear. In the chronic phase, the diagnosis is based on biopsy or serologic assays. There are nationally standardized treatments for the acute phase, which consist of ciprofloxacin, and alternatively chloramphenicol plus penicillin G. However, most of the treatments are based on evidence from reported cases. During the eruptive phase the recommended treatment is rifampin, and alternatively, azithromycin or erythromycin.

Formas atípicas de enfermedad por arañazo de gato, Valdivia / Atypical presentation of Cat Scratch Disease in Valdivia

La enfermedad por arañazo de gato (EAG), es considerada la causa más frecuente de linfoadenopatía benigna crónica en niños y adolescentes. En los casos existe el antecedente de contacto con gatos (90 por ciento) y de rasguño y/o mordedura (60 por ciento). La infección con Bartonella spp se manifiesta como desde una linfoadenopatía (EAG) a una enfermedad sistémica. El 10 po ciento tiene manifestaciones atípicas y 2 por ciento presenta complicaciones graves. Debe sospecharse EAG por exclusión de otras etiologías habituales y por el antecedente epidemiológico de contacto y/o rasguño de gato, con o sin lesión de inoculación primaria. Se presentan 4 casos de EAG atípicas en niños del S.S. Valdivia, donde se confirmó el agente por IFI IgG contra Bartonella henselae, con títulos > 1: 256.

Doença da arranhadura do gato simulando carcinoma oculto da mama / Cat scratch disease like occult breast cancer

Paciente de 44 anos com massa axilar pétrea, fixa, indolor, medindo 4cm de diâmetro. À mamografia, evidenciou-se massa hiperdensa em prolongamento axilar esquerdo (categoria IV Bi-Rads); a ultra-sonografia mostrou imagem nodular hipoecóica com área ecogênica central, de contornos parcialmente regulares, medindo 3,4cm x 2,1cm. Apresentava hipervascularização ao doppler colorido sugerindo linfonodo atípico. Estudo histopatológico evidenciou seis linfonodos, medindo, o maior, 2,5cm x 1,6cm, os quais mostravam granuloma de células gigantes, multinucleadas, células epitelióides, necrose central com debris celulares e leucócitos polimorfonucleares. Os achados histopatológicos eram compatíveis com linfadenite granulomatosa, doença da arranhadura do gato. O carcinoma oculto da mama se apresenta com massa axilar suspeita, sendo altamente recomendável estudo histopatológico antes de decisão terapêutica. A doença da arranhadura do gato é causa de linfadenite regional subaguda. É causada pela inoculação da Bartonella henselae através de arranhaduras ou mordidas de gatos. O período de incubação é de três a 30 dias, aos quais se segue o aparecimento de pápulas ou vesículas avermelhadas no sítio de inoculação.

We studied the case of a 44-year-old female patient with a hard, painless and fixed axillary mass with 4cm in diameter. The mammography showed a dense axillary mass, at the axillary tail. Ultrasonography showed a hypoecoic nodule with central ecogenicity and regular borders, measuring 3.4cm x 2.1cm, with hypervascularization in doppler color suggesting atypical lymphonode. The histopathologic study found six lymphonodes, the bigger one measured 2.5cm x 1.6cm with giant cells granuloma, multinuclear cells, epithelioid cells, central necrosis with debris and polymorphonuclear cells, suggesting granulomatosis lymphadenitis, cat scratch disease. Actually, occult breast carcinoma clinically shows an axillary mass and the histopathologic study is highly recommended before the therapeutic decision is made. The etiology of the cat scratch disease is the inoculation of Bartonella henselae by scratch or bite of cats. It causes a regional subacute lymphadenitis with an incubation period from three to 30 days where the acommited site presents with red skin and papules or vesicles.
