Pulmonary histoplasmoma: a disguised malady

Histoplasmosis is a mycosis caused by the dimorphic fungus, Histoplasma capsulatum, which is transmitted via dust and aerosols. Lung involvement is the most common, with a varied clinical presentation. Although it is not the only source of infection, H. capsulatum is frequently found in bat guano, which is the reason why it is highly prevalent among caving practitioners. The solitary histoplasmoma of the lung is an unusual and chronic manifestation of this entity, which mimics, or at least is frequently misconstrued, as a malignancy. Almost invariably, the diagnosis of this type of histoplasmosis presentation is achieved after lung biopsy. The authors present the case of a young woman who sought medical care because of chest pain. The diagnostic work-up revealed the presence of a pulmonary nodule. She was submitted to a thoracotomy and wedge pulmonary resection. The histologic analysis rendered the diagnosis of histoplasmoma. Thisreport aims to call attention to this diagnosis as the differential diagnosis of a pulmonary nodule.

Pulmonary paracoccidioidomycosis: a case report of reactivation in a patient receiving biological therapy

Abstract Paracoccidioidomycosis is an endemic disease in Latin America that is rarely associated with immunosuppression and biological therapy. Herein, we report for the first time a case of pulmonary paracoccidioidomycosis reactivation after infliximab treatment. A 47-year-old man from Brazil received infliximab to treat psoriatic spondyloarthropathy and presented with cough, dyspnea, weight loss, and fever. Chest computed tomography revealed a pulmonary nodule and biopsy confirmed paracoccidioidomycosis. Treatment with sulfamethoxazole and trimethoprim was initiated for fungal infection and infliximab was reintroduced two months later. Considering his clinical improvement and favorable radiologic evolution, antifungal therapy was discontinued after 29 months.

Micosis pulmonares en niños: un enfoque diagnóstico / Pulmonary mycosis in children: a diagnostic approach

Pulmonary mycoses are invasive fungal infections that occur more and more frequently. The rising number of patients with immunodeficiencies, HIV infection, hematopoietic stem cell and solid organ transplant recipients, as well as the use of immunosuppressive therapies have increased the incidence of this disease. Diagnosis remains a challenge because the most accurate procedure is the isolation of the germ through culture of body fluids which have low sensitivity and a long development time (4-6 weeks). The diagnosis of pulmonary mycoses is based on the presence of risk factors, clinical and/or radiological symptoms suggestive of fungal infection and a positive microbiological test. Due to the fact that pulmonary mycoses are not usually considered in the differential diagnosis in the initial clinical evaluation of diseases and that the studies to establish the diagnosis are complex, they are diagnosed late when they have already become chronic with a high risk of morbidity and mortality

Las micosis pulmonares son infecciones invasivas que se presentan cada vez con mayor frecuencia en la población. El aumento del número de pacientes con inmunodeficiencias, infección por VIH, receptores de trasplante de células hematopoyéticas y órgano sólido, así como el uso de terapias inmunosupresoras ha incrementado la incidencia de esta enfermedad. El diagnóstico continúa siendo un reto debido a que el estándar de oro es el aislamiento del germen mediante cultivo de líquidos corporales los cuales tienen baja sensibilidad y un tiempo de desarrollo prolongado (4-6 semanas). El diagnóstico de las micosis pulmonares se basa en la presencia de factores de riesgo, cuadro clínico y/o radiológico sugestivo de infección fúngica y el estudio microbiológico positivo. Debido a que las micosis pulmonares habitualmente no se consideran dentro del diagnóstico diferencial en la evaluación clínica inicial de las enfermedades, asociado a la complejidad de estudios para establecer el diagnostico, las micosis pulmonares se diagnostican en forma tardía cuando ya existe enfermedad crónica, con alto riesgo de morbimortalidad

Serum markers as an aid in the diagnosis of pulmonary fungal infections in AIDS patients

ABSTRACT Introduction: The etiology of pulmonary infections in HIV patients is determined by several variables including geographic region and availability of antiretroviral therapy. Materials and methods: A cross-sectional prospective study was conducted from 2012 to 2016 to evaluate the occurrence of pulmonary fungal infection in HIV-patients hospitalized due to pulmonary infections. Patients' serums were tested for (1-3)-β-D-Glugan, galactomannan, and lactate dehydrogenase. The association among the variables was analyzed by univariate and multivariate regression analysis. Results: 60 patients were included in the study. The patients were classified in three groups: Pneumocystis jirovecii pneumonia (19 patients), community-acquired pneumonia (18 patients), and other infections (23 patients). The overall mortality was 13.3%. The time since diagnosis of HIV infection was shorter in the pneumocystosis group (4.94 years; p = 0.001) than for the other two groups of patients. The multivariate analysis showed that higher (1-3)-β-D-Glucan level (mean: 241 pg/mL) and lactate dehydrogenase (mean: 762 U/L) were associated with the diagnosis of pneumocystosis. Pneumocystosis was the aids-defining illness in 11 out of 16 newly diagnosed HIV-infected patients. Conclusion: In the era of antiretroviral therapy, PJP was still the most prevalent pulmonary infection and (1-3)-β-D-Glucan and lactate dehydrogenase may be suitable markers to help diagnosing pneumocystosis in our HIV population.

Tuberculosis and fungal co-infection present in a previously healthy patient / Coinfección de tuberculosis y candidiasis pulmonar en paciente previamente sana

Background: The coexistance among fungal pathogens and tuberculosis pulmonary is a clinical condition that generally occurs in immunosuppressive patients, however, immunocompetent patients may have this condition less frequently. Objective: We report the case of an immunocompetent patient diagnosed with coinfection Mycobacterium tuberculosis and Candida albicans. Case Description: A female patient, who is a 22-years old, with fever and a new onset of hemoptysis. Clinical findings and diagnosis: PDiminished vesicular breath sounds in the apical region and basal crackling rales in the left lung base were found in the physical examination. Microbiological tests include: chest radiography and CAT scan pictograms in high resolution, Ziehl-Neelsen stain, growth medium for fungus and mycobacteria through Sabouraudís agar method with D-glucose. Medical examinations showed Candida albicans fungus and Mycobacterium tuberculosis present in the patient. Treatment and Outcome: Patient was treated with anti-tuberculosis and anti-fungal medications, which produced good responses. Clinical relevance: Pulmonary tuberculosis and fungal co-infection are not common in immunocompetent patients. However, we can suspect that there is a presence of these diseases by detecting new onset of hemoptysis in patients.

Antecedentes: La coexistencia entre los hongos patógenos y la tuberculosis pulmonar es una condición clínica que se produce generalmente en pacientes inmunosuprimidos, sin embargo, los pacientes inmunocompetentes puede tener esta condición con menor frecuencia. Objetivo: Presentamos el caso de un paciente inmunocompetente con diagnóstico de una coinfección de tuberculosis Mycobacterium tuberculosis y Candida albicans. Caso clínico: Paciente femenina de 22 años con cuadro abrupto de tos, fiebre y hemoptisis sin antecedentes de enfermedad. Hallazgos clínicos y métodos diagnósticos: Al examen respiratorio se halló disminución del murmullo vesicular en la región apical y estertores crepitantes basales en el pulmón izquierdo. Se realizó estudios microbiológicos de muestras tomadas por expectoración y por fibrobroncoscopia en el que se incluyó la tinción de Ziehl-Neelsen, cultivo para micobacteria y hongos en medio Agar Dextrosa Sabouraud y filamentización en suero obteniéndose positividad para Mycobacterium tuberculosis y Candida albicans. Tratamiento y resultado: Se le realizó manejo con antifímicos de primera categoría y antimicóticos con buena respuesta clínica. Relevancia clínica: La coinfección fúngica y tuberculosis pulmonar no es frecuente en pacientes inmunocompetentes, debe sospecharse en episodios abruptos de hemoptisis.

Rapid detection of Candida species in bronchoalveolar lavage fluid from patients with pulmonary symptoms

Abstract Candida species, especially C. albicans, are commensals on human mucosal surfaces, but are increasingly becoming one of the important invasive pathogens as seen by a rise in its prevalence in immunocompromised patients and in antibiotic consumption. Thus, an accurate identification of Candida species in patients with pulmonary symptoms can provide important information for effective treatment. A total of 75 clinical isolates of Candida species were obtained from the bronchoalveolar lavage fluid of both immunocompromised and immunocompetent patients with pulmonary symptoms. Candida cultures were identified based on nuclear ribosomal Internal Transcribed Spacer (ITS1-ITS2 rDNA) sequence analysis by polymerase chain reaction–restriction fragment length polymorphisms (PCR-RFLP). Molecular identification indicated that the isolates belonged predominantly to C. albicans (52%), followed by C. tropicalis (24%), C. glabrata (14.7%), C. krusei (5.3%), C. parapsilosis (1.3%), C. kefyr (1.3%) and C. guilliermondii (1.3%). Given the increasing complexity of disease profiles and their management regimens in diverse patients, rapid and accurate identification of Candida species can lead to timely and appropriate antifungal therapy.

Importancia diagnóstica de las infecciones extrapulmonares causadas por el género Mycobacterium / Diagnostic importance of extrapulmonary infections caused by the genus Mycobacterium

Introducción: el género Mycobacterium provoca infecciones pulmonares y extrapulmonares, dentro de estas últimas las localizaciones más frecuentes son; sistema nervioso linfático, central, circulatorio, genitourinario, gastrointestinal, tejido osteoarticular, y la piel. Objetivo: realizar las caracterizaciones etiológica de infecciones extra pulmonares producidas por el género Mycobacterium, destacar su importancia diagnóstica tanto en pacientes VIH- como VIH/sida. Métodos: se realiza un estudio descriptivo-prospectivo de corte transversal realizado de enero 2012 a mayo 2014. Durante este período se recibió un total de 825 muestras, 232 de pacientes VIH- y 593 de pacientes con VIH/sida. Las muestras que lo requerían se le aplicaron descontaminación cultivo, se utilizó el método de ácido sulfúrico al 4 por ciento, para el cultivo se usó el medio de Löwenstein-Jensen.

Conclusión: por todo lo anterior expuesto se recomienda mantener la vigilancia diagnóstica en este tipo de infección extra pulmonar, en especial en pacientes con sida, pues en muchos casos pueden tener fatales consecuencias por su diagnóstico tardío(AU)

Chronic Cavitary Pulmonary Histoplasmosis in a Non-HIV and Immunocompromised Patient without Overseas Travel History

Korea is not known as an endemic area for Histoplasma. However, we experienced a case of histoplasmosis in a person who had never been abroad. A 65-year-old female was admitted to the hospital for evaluation of multiple lung nodules. A computed tomography (CT) scan of the chest showed multiple ill-defined consolidations and cavitations in all lobes of both lungs. The patient underwent a CT-guided lung biopsy, and a histopathology study showed findings compatible with histoplasmosis. Based on biopsy results and clinical findings, the patient was diagnosed with chronic cavitary pulmonary histoplasmosis. The patient recovered completely following itraconazole treatment. This is the first case report of pulmonary histoplasmosis unconnected with either HIV infection or endemicity in Korea.

The pulmonary cavity is often result cured pulmonary tuberculosis with hemoptisis repletion history and bacilloscopy negative. The authors analyzed retrospectively 190 cases of CIPA from April 1978 to March 2008 in the University Hospital Lauro Wanderley and Hospital Complex Clementino Fraga emphasizing the incidence, clinical evolution, illness association, diagnosis method and treatment.

Falla de tratamiento en neumonía adquirida en la comunidad: coccidioidomicosis en un viajero / Treatment failure in community-adquired pneumonia: coccidioidomycosis in a traveler patient

Treatment failure in community-acquired pneumonia is defined as a clinical condition with inadequate response to antimicrobial therapy. Resistant and unusual microorganisms and noninfectious causes are responsible for treatment failure. Coccidioides immitis is a fungus that causes pneumonia in the northern hemisphere, especially in the United States and northern Mexico. We report a case of pulmonary coccidioidomycosis imported from Mexico to Chile. After a comprehensive study, histopathology was able to establish Coccidiodes immitis as the causative agent, achieving clinical and radiological improvement with antifungal therapy.

La neumonía de evolución tórpida son aquellas en que no se logra una respuesta clínica adecuada con el uso de terapia antimicrobiana. Existen múltiples causas a esta falta de respuesta: resistencia antimicrobiana, microorganismos no cubiertos o infecciones por microorganismos atípicos. Coccidioides immitis es un hongo causante de neumonía en el hemisferio norte, especialmente en E.U.A y norte de México. No existen reportes de casos pulmonares importados en Chile. Presentamos el caso de una mujer adulta con una neumonía que no respondió al tratamiento antimicrobiano habitual. Una vez realizado un estudio exhaustivo, se logró establecer mediante el estudio histopatológico la existencia de una coccidiodomicosis como entidad causal, logrando una respuesta clínica y radiológica favorable al tratamiento antifúngico.

Histoplasmosis presenting with multiple pulmonary nodules. A case mimicking radiological features of pulmonary metastasis / Histoplasmose apresentando múltiplos nódulos pulmonares. Um caso simulando características radiológicas de metástase pulmonar

We present a case of histoplasmosis with multiple pulmonary nodules in a patient with a history of melanoma. This case closely simulated malignancy, including the presence of feeding vessel sign, which occurs in pulmonary metastasis. We emphasize the need to be aware of this infection in areas where histoplasmosis is endemic.

Apresentamos caso de histoplasmose com múltiplos nódulos pulmonares em paciente com história de melanoma. Este caso simula malignidade, incluindo o sinal de vaso nutridor que ocorre na metástase pulmonar. Enfatizamos a necessidade de considerar esta infecção em áreas onde a histoplasmose é endêmica.

A propósito de un caso: micosis pulmonar en paciente pediátrico con enfermedad granulomatosa crónica / Case report: pulmonary mycosis in children with chronic granulomatous diseaseSE

A 8-year-old girl, born and resident of Guárico state, was referred to our Department because of a history of recurrent pneumonia and a history of deceased sister by unspecified lung disease. At the age of 4 years she had suffered several episodes of pneumonia requiring hospitalization. These episodes were no-responsive to antibiotic therapy and treatment for tuberculosis. Subsequently, At the age of 8 years she was hospitalized again for an episode of left lower lobe pneumonia that did not improve. Studies were performed to rule out pulmonary pathology disease: Cystic Fibrosis was discarded and also Pulmonary Tuberculosis. Serology for HIV and Fungi were negative. Because serological studies were inconclusive, a videobronchoscopy plus Bronchoalveolar lavage and lung tissue biopsy were performed, which reported bronchitis and chronic granulomatous and caseous necrosis. Special stains were observed that suggest fungus infection. Primary immunodeficiency was suspected in the patient, because the presence of recurrent pneumonia of different etiologies. The presence of the granuloma observed by the videobronchoscopy. A positive culture for Histoplasma and Aspergillus fungi, and the result of the oxidative capacity test, where the deficiency was observed in the microbicidal activity of macrophages. They were strong evidence that corroborated the immunodeficiency called Chronic Granulomatous Disease.

Escolar femenino de 8 años de edad, natural y procedente del Estado Guárico, con antecedente de hospitalizaciones por neumonías recurrente desde los 4, recibió antibioticoterapia endovenosa y cumplió tratamiento antifímico en dos oportunidades, persistiendo con sintomatología respiratoria. A los 8 años precisó nueva hospitalización por diagnóstico de neumonía del lóbulo inferior izquierdo. Por no presentar mejoría y antecedente de hermana fallecida por patología pulmonar no precisada fue referida a nuestro centro. Se realizaron estudios por patología pulmonar crónica: se descartó Fibrosis Quística y Tuberculosis Pulmonar. Serología para HIV y Hongos Negativa. Por no ser concluyentes los estudios serológicos se realizó Videobroncoscopia más lavado y biopsia, la cual reportó bronquitis crónica granulomatosa y necrosis caseosa. Coloraciones especiales: hongos intracitoplasmáticos sugestivos de Histoplasma Sp. y en el cultivo presentó crecimiento de Aspergillus fumigatus. Ante la presencia de paciente con neumonía recurrente por diferentes etiologías se sospechó la presencia de Inmunodeficiencia Primaria, planteando en base al reporte de la videobroncoscopia de granuloma y la confirmación de Infección por Histoplasma y Aspergillus una Enfermedad Granulomatosa Crónica que fue documentada al medir la deficiencia en la actividad microbicida dependiente de oxigeno evaluada a través del Test de Capacidad Oxidativa.

Pulmonary cryptococcosis in non-AIDS patients

OBJECTIVE: To investigate the clinical features, management, and prognosis of pulmonary cryptococcosis in non-acquired immunodeficiency syndrome (AIDS) patients. METHOD: 24 cases of pulmonary cryptococcosis with accurate pathological diagnosis were retrospectively studied. RESULTS: 15 male patients and nine female patients were diagnosed at the first affiliated hospital of Sun Yat-sen University from November 1999 to November 2011. The mean age at the time of diagnosis was 44.2 ± 11.3 years (range: 24 to 65 years). Among these patients, 13 had other comorbidities. 15 were symptomatic and the other nine were asymptomatic. The most common presenting symptoms were cough, chest tightness, expectoration, and fever. None had concurrent cryptococcal meningitis. The most frequent radiologic abnormalities on chest computed tomography (CT) scans were solitary or multiple pulmonary nodules, and masses or consolidations, and most lesions were located in the lower lobes. All patients had biopsies for the accurate diagnosis. Among the 24 patients, nine patients underwent surgical resections (eight had pneumonectomy via thoracotomy and one had a pneumonectomy via thoracoscopy). Five of the patients who underwent surgery also received antifungal drug therapy (fluconazole) for one to three months after the surgery. The other 15 only received antifungal drug therapy (fluconazole or voriconazole) for three to six months (five patients are still on therapy). The follow-up observation of 19 patients who had already finished their treatments lasted from two to 11 years, and there was no relapse, dissemination, or death in any of these patients. CONCLUSION: Non-AIDS patients with pulmonary cryptococcosis have a good prognosis with appropriate management.

Not all that shines is cancer: pulmonary cryptococcosis mimicking lymphoma in [(18)] F fluoro-2-deoxy-D-glucose positron emission tomography / Nem tudo o que brilha é câncer: criptococose pulmonar mimetizando linfoma na tomografia por emissão de pósitrons com [(18)] F fluoro-2-desoxi-D-glicose

We report of a case of pulmonary cryptococcosis mimicking lymphoma in a positron emission tomography (FDG-PET) scan. A 62-year old man with diffuse large B-cell lymphoma had complete resolution of abdominal and pulmonary lesions after three cycles of rituximab-based chemotherapy (R-CHOP). However, FDG-PET showed new pulmonary nodules, suggesting active lymphoma. Chronic inflammatory granuloma was seen in the histopathological exam, with round-shaped structures compatible with fungus, later identified as Cryptococcus neoformans on culture. The lesions disappeared after 6 weeks of fluconazole therapy, and the patient could continue chemotherapy without further infectious complications.

Homem de 62 anos com resolução completa, ao PET-scan, de seu linfoma não Hodgkin de células B, lesões abdominais e pulmonares, após três ciclos de quimioterapia baseada em ritoximabe (R-CHOP). Entretanto, o mesmo exame mostrou também novos nódulos pulmonares, sugestivos de lesões do linfoma. Granuloma inflamatório crônico foi observado no exame anatomopatológico, com estruturas circulares compatíveis com fungo. Cultura revelou Cryptococcus neoformans. As lesões desapareceram após 6 semanas de fluconazol, e o paciente pôde continuar a quimioterapia sem complicações infecciosas.

Coccidioidomycosis in armadillo hunters from the state of Ceará, Brazil

Coccidioidomycosis is a systemic mycosis with a variable clinical presentation. Misdiagnosis of coccidioidomycosis as bacterial pneumopathy leads to inappropriate prescription of antibiotics and delayed diagnosis. This report describes an outbreak among armadillo hunters in northeastern Brazil in which an initial diagnosis of bacterial pneumonia was later confirmed as coccidioidomycosis caused by Coccidioides posadasii. Thus, this mycosis should be considered as an alternative diagnosis in patients reporting symptoms of pneumonia, even if these symptoms are only presented for a short period, who are from areas considered endemic for this disease.

Un caso excepcional de paracoccidioidomicosis e histoplasmosis pulmonares de presentación concomitante / Concomitant pulmonary paracoccidioidomycosis and pulmonary histoplasmosis: a rare case

La incidencia de las micosis pulmonares en Uruguay es muy baja, y estas usualmente aparecen en pacientes inmunocomprometidos. Se discute el caso de un paciente inmunocompetente proveniente de área rural, que presenta tos, disnea y fiebre de dos meses de evolución. La imagenología mostró una neumonitis extensa y fibrosis pulmonar. Los test micológicos directos, cultivo y serológicos muestran histoplasmosis y paraccocidioidomicosis en forma concomitante. El paciente presentó hipotensión arterial diagnosticándose una insuficiencia suprarrenal. A pesar de que la extensa fibrosis pulmonar y la neumonitis no fueron reversibles, el paciente mejoró clínicamente con el tratamiento antifúngico. Se trata de un caso excepcional de dos micosis pulmonares en un mismo paciente.

The incidence of pulmonary fungal infections is very low in Uruguay, and such infections typically affect immunocompromised patients. We report the case of an immunocompetent patient presenting with a two-month history of cough, dyspnea, and fever. The patient resided in a rural area. Imaging tests revealed extensive pneumonitis and pulmonary fibrosis. On the basis of direct mycological examination, culture, and serological testing, we made a diagnosis of concomitant histoplasmosis and paracoccidioidomycosis. The patient presented arterial hypotension that was diagnostic of adrenocortical insufficiency. Although the pulmonary fibrosis and pneumonia were irreversible, the clinical condition of the patient improved after antifungal treatment. This was an exceptional case of two pulmonary fungal infections occurring simultaneously in the same patient.

Infección diseminada por Penicillium marneffei en un paciente HIV-positivo: Primera observación en la República Argentina / Disseminated infection due to Penicillium marneffei related to HIV infection: First observation in Argentina

Se presenta el primer caso humano de peniciliosis por Penicillium marneffei observado en la República Argentina. El paciente era un joven de 16 años, HIV-positivo, procedente de un área rural del sur de China. El paciente fue internado en el Hospital "F. J. Muñiz" por padecer una neumonía grave con insufciencia respiratoria aguda. El agente causal fue aislado de un lavado broncoalveolar y se lo observó en un citodiagnóstico de piel. La identifcación de P. marneffei fue confrmada por las características fenotípicas del aislamiento y la amplifcación del ADNr. El enfermo padecía una infección muy avanzada por HIV que condujo a la aparición simultánea de infecciones por citomegalovirus, Pneumocystis jirovecii y procesos bacterianos nosocomiales. Este complejo cuadro derivó en una evolución fatal.

The frst case observed in Argentina of AIDS-related human penicillosis is herein presented. The patient was a six- teen year-old young man coming from a rural area of southern China. He was admitted at the F. J. Muñiz Hospital of Buenos Aires city with severe pneumonia and adult respiratory distress. Penicillium marneffei was isolated from bronchoalveolar lavage fuid and was microscopically observed in a skin cytodiagnosis. P. marneffei identifcation was confrmed by rRNA amplifcation and its phenotypic characteristics. The patient suffered an advanced HIV infection and also presented several AIDS-related diseases due to CMV, nosocomial bacterial infections and Pneumocystis jirovecii which led to a fatal outcome.
