Laryngeal Histoplasmosis: report first case in Colombia / Histoplasmosis laríngea: reporte de primer caso en Colombia

Laryngeal histoplasmosis is a fungal infection that is frequent in Colombia. Laryngeal histoplasmosis usually occurs in immunocompromised patients through the dissemination of the fungus from the lungs to other organs. Histoplasmosis isolated laryngeal (primary) is rare. If a patient presents with a history of immunosuppression by renal transplant, primary laryngeal histoplasmosis with supraglottic granulomatous inflammation that was treated with amphotericin B and Itraconazole, with complete resolution of laryngeal lesions.

Histoplasmosis es una infección fúngica que es frecuente en Colombia. La histoplasmosis laríngea por lo general se presenta en pacientes inmunocomprometidos por la difusión del hongo desde los pulmones a otros órganos. La enfermedad laríngea aislada (primaria) es rara. Se presenta el caso de un paciente con antecedente de inmunosupresión por trasplante renal, con histoplasmosis laríngea primaria que produjo inflamación granulomatosa supraglótica, tratado con Anfotericina B e Itraconazol, con resolución completa de las lesiones laríngeas.

Lesões sequelares na laringe em pacientes com paracoccidiodomicose / Sequelae lesions in the larynxes of patients with paracoccidioidomycosis

A Paracoccidioidomicose (PCM) é uma doença sistêmica que em sua forma sequelar se caracteriza por manifestações clínicas relacionadas às alterações anatômicas ou funcionais de órgãos e sistemas comprometidos no período de estado. OBJETIVO: Descrever as alterações anatômicas e funcionais laríngeas sequelares em pacientes com paracoccidioidomicose. MATERIAL E MÉTODOS: Estudo retrospectivo, sendo avaliados 49 pacientes do sexo masculino, na faixa etária de 30 a 60 anos, entre 1999 a 2004, com diagnóstico de PCM em acompanhamento pela disciplina de Moléstias Infecciosas e Parasitárias, confirmado pela demonstração do fungo em escarro, exame citológico ou histopatológico. RESULTADOS: As pregas vocais foram a estrutura laríngea mais afetada, em 67 por cento dos pacientes verificaram-se alterações. A epiglote estava acometida em 55 por cento dos casos. As pregas ariepiglóticas tinham modificações em 53 por cento dos pacientes. As pregas vestibulares estavam alteradas em 46 por cento dos casos. Em 40 por cento dos casos verificaram-se alterações em aritenoides. Na fonação, 28 por cento tinham limitação ao movimento das cordas vocais, paresia unilateral ocorreu em 4 por cento casos. Em 24 por cento havia restrição da luz supraglótica e 4 por cento tinham estenose glótica, sendo que 2 por cento precisaram de traqueotomia. CONCLUSÃO: As lesões sequelares na laringe devido à infecção pelo P. brasilienses são extensas e causam restrições funcionais na maioria dos casos.

Paracoccidioidomycosis (PCM) is a systemic disease that in its aftermath form is characterized by clinical manifestations related to anatomic or functional sequelae of organs and systems affected during the period of state. AIM: To describe the anatomical and functional sequelae in patients with treated laryngeal PCM. MATERIALS AND METHODS: Retrospective study. We reviewed the charts from of 49 male patients, aged between 30 to 60 years, diagnosed with laryngeal PCM during the period of 1999 to 2004. In all patients the diagnosis of PCM was confirmed by demonstration of the fungus in sputum, cytological or histopathological examination and being followed up by the Infectious and Parasitic Diseases Department. RESULTS: The vocal folds were the most affected laryngeal structure, being affected in 67 percent of the patients. The epiglottis and the aryepiglottic folds were affected in 55 percent and 53 percent of the cases, respectively. Vestibular folds were changed in 46 percent of the patients. In 40 percent of the cases there were changes in the arytenoids. During phonation, 28 percent of the patients showed limited movement of the vocal folds, unilateral vocal fold paralysis was found in 4 percent. 24 percent of the cases had glottic lumen reduction and 4 percent showed glottic stenosis, 2 percent needed tracheostomy. CONCLUSION: Sequela lesions of the laryngeal PCM are extensive and cause functional limitations in most cases.

Actinomycosis larynx: a rare entity

Our patient, a fifty five year old poultry farmer presented with two years history of throat discomfort, for which he had taken steam inhalation. For the last two months he noticed a change in his voice. On examination he was found to be hoarse. His Indirect Laryngoscopy [IDL] showed oedematous cords. He underwent DL, which revealed oedematous cords with yellowish spots. Histopathology report received showed actinomycosis larynx. Final diagnosis of Actinomycosis larynx was made because of presence of Sulphur granules [yellow spots] on naked eye examination of vocal cords during DL, and a positive hitopathology report. The patient was started on Injection Benzyl Penicillin one million unit international units intravenous four times a day. This dose was continued for four weeks after which patient were shifted on tablet ciprofloxacin 500 mg twice daily due to unavailability of oral penicillin V. The oral therapy was continued for 3-6 months depending upon the response. During the treatment the hoarseness settl ed and IDL showed reduction in odema of the vocal cords

Histoplasmose de laringe / Histoplasmosis of the larynx

A histoplasmose com acometimento único de laringe é uma ocorrência rara da doença, com menos de 100 casos relatados na literatura, quando comparada ao número de pacientes diagnosticados com histoplasmose. Tal localização, quando isolada, pode induzir, erroneamente, ao diagnóstico e tratamento de tuberculose ou câncer de laringe, com casos relatados de tratamentos iniciados para essas doenças. Em um paciente com histoplasmose que desenvolva rouquidão, deve-se pensar no acometimento laríngeo da histoplasmose, enquanto que uma massa laríngea produzindo rouquidão deve incluir em seu diagnóstico diferencial a histoplasmose laríngea. Quando se pensa em histoplasmose como causa de uma lesão laríngea, a biópsia deve ser limitada, removendo a menor quantidade de tecido necessária para o diagnóstico O patologista deve ser avisado da possibilidade do diagnóstico, já que podem ser necessários corantes especiais para o diagnóstico.

The incidence of laryngeal histoplasmosis is low when compared to the total number of cases. Less than 100 cases of laryngeal histoplasmosis have been described in the medical literature. Isolated laryngeal involvement may lead to the misdiagnosis and mistreatment of tuberculosis or laryngeal cancer, according to some reports. The development of hoarseness in a patient with histoplasmosis or a laryngeal mass leading to hoarseness, might be suggestive of laryngeal histoplasmosis. When histoplasmosis is included among the differential diagnoses of a laryngeal lesion, the biopsy should be limited to a small tissue fragment, enough to perform histological tests. The laboratory technicians must be warned about the possibility of histoplasmosis, because special dyes have to be used to confirm this diagnosis.

Disseminated histoplasmosis mimicking laryngeal carcinoma from central India--a case report.

A 58 year old male, chronic smoker, with diabetes mellitus (Type II), residing in Madhya Pradesh presented with dysphagia, hoarseness, odynophagia and significant weight loss. Microlaryngoscopy showed reddish ulcerated area involving valleculae, and pharyngo-epiglottic fold. Histopathological examination showed foamy macrophages containing Histoplasma capsulatum. Patient initially responded to Azoles, relapsed three months after stopping the treatment and presented with oral lesions. Biopsy showed H. capsulatum, histologically as well as on culture. The mycelial phase converted to yeast phase on B.H.I.A. at 37 degrees C confirming the isolate as H. capsulatum. The patient responded well to amphotericin B.

Blastomicose de laringe: descriçäo de um caso / Larynx blastomycosis: report of case

A blastomicose de laringe, a tuberculose de laringe e a laringite sifilítica pertencem ao grupo das laringites específicas, que säo excepcionais na atualidade. Entretanto ainda säo freqüentes em certos países tropicais. Os autores descrevem um caso de blastomicose de laringe e ressaltam a importância da biópsia no diagnóstico preciso da patologia.

Detección y tipificación del virus papiloma humano en lesiones laríngeas con técnica de hibridación molecular in situ / Detection and typification of human papilloma virus in laryngeal lesions with the technique of molecular hybridization in situ

Se ensayó la técnica de hibridación molecular in situ en lesiones papilomatosas de la laringe, con el objetivo de detectar material genético de virus papiloma humano (VPH), identificar los tipos virales involucrados en la infección, establecer relación de diagnóstico histológico con el virológico y verificar si, a determinados cambios histopatológicos, se asocian genotipos específicos. En ocho pacientes adultos portadores de papilomatosis laríngea se revisaron, retrospectivamente, aspectos clínicos y del tejido de biopsia. Se analizaron histopatológicamente las muestras, verificando la existencia de displasia y actividad viral, y se sometieron los tejidos al estudio de hibridación molecular de ácidos nucleicos in situ. Estos aspectos se realizaron independientemente siendo por tanto un estudio doble ciego. Detectamos genotipos virales en 7 de los 8 pacientes. Tres de ellos fueron positivos para los tipos 6-11 y se asociaron a grados de displasia leves y signos de actividad viral evidente. Cuatro pacientes fueron positivos para los tipos 16-18 y presentaron grados de displasia moderada y severa con pocos signos de actividad viral. Los resultados inducen a pensar que los genotipos 6-11 se asocian a lesiones de pronóstico benigno y los 16-18 a lesiones que podrían resultar malignas debiendo considerarse la infecciones por VPH en la laringe, especialmente las producidas por subtipos 16-18, como de riesgo, dado que estas serian cofactores carcinogenéticos
