Actinomicosis ósea del antepié izquierdo. Presentación de un caso / Bone actinomycosis of the left forefoot. Presentation of a case

RESUMEN Se presentó el caso de una actinomicosis ósea, que se manifestó como una lesión de la piel en la zona correspondiente al segundo metatarsiano izquierdo. Por el antecedente de ser la paciente operada de un tumor de células gigantes, se pensó en una recidiva tumoral. Fue intervenida quirúrgicamente y se realizó exéresis del segundo metatarsiano y de la piel afectada. La biopsia informó actinomicosis. Se trató a la paciente con amoxicilina; evolucionando satisfactoriamente, y dando seguimiento en consulta (AU).

ABSTRACT The authors presented the case of a bone actinomycosis expressed as a skin lesion in the area of the second left metatarsals. Due to the antecedent of having undergone a surgery of a giant cell tumor, a tumor recurrence was thought. Surgical intervention was performed and the excision of the second metatarsals and affected skin was performed. The biopsy reported Actinomycosis. The patient was treated with amoxicillin. She had a satisfactory evolution and is still followed up in consultation (AU).

Actinomycosis is not Frequent in the Periapex But is a Persistent Lesion

Abstract Periapical actinomycosis caused by a gram-positive anaerobic pathogen characterizes a typical extra-radicular infection. This study determined the frequency and correlated the content of bacteria colonies with the of periapical actinomycosis size. The study comprised a total of 218 periapical lesions (PL) (cysts, granulomas or abscess). The specimens embedded in paraffin were sliced into 4-µm sections and stained with hematoxylin-eosin, Gram, Periodic Acid-Schiff (PAS) and Grocott's stain. The presence of bacterial colonies composed of filamentous structures labeled with the histochemical stains were described as Actinomyces, and for each case, the bacterial colonies were counted and measured. The correlation between the number and size of bacterial colonies and the size of PL was tested using Pearson's adjusted correlation coefficient. From 218 PL, bacterial colonies were identified in 64 biopsies. Seven cases (0.3%) fulfill the criteria for diagnosis of periapical actinomycosis. All of cases were therapy-resistant and did not showed periapical repair after 12 months of follow-up. Periapical surgery or dental extraction was performed. The correlation test indicated no correlation between the number of bacterial colonies and the lesion size (p=0.752, r=-0.148). However, a larger bacterial colony size generally resulted in a larger periapical lesion (P=0.000, r=0.657). The frequency of periapical actinomycosis was low, and this lesion should be included in the differential diagnosis of PL. The size of the Actinomyces colonies seemed to contribute to increase the size of the periapical lesion.

Resumo A actinomicose periapical causada por um patógeno anaeróbio Gram positivo caracteriza uma infecção extra-radicular típica. Esse estudo determinou a frequência e correlacionou o conteúdo das colônias bacterianas com o tamanho das actinomicoses periapicais. O estudo compreendeu um total de 218 lesões periapicais (LPs) (cistos, granulomas ou abscessos). Os espécimes embebidos em parafina foram cortados em secções de 4-µm e corados com hematoxilina-eosina, Gram, ácido periódico de Schiff (PAS) e coloração de Grocott. A presença de colônias bacterianas compostas por estruturas filamentosas marcadas com os corantes histoquímicos foram descritas como Actinomyces, e para cada caso, as colônias bacterianas foram contadas e mensuradas. A correlação entre o número e tamanho das colônias bacterianas e o tamanho das LPs foi testado usando o coeficiente de correlação ajustado de Pearson. De 218 LPs, colônias bacterianas foram identificadas em 64 biópsias. Sete casos (0,3%) preencheram os critérios para o diagnóstico de actinomicose periapical. Todos os casos foram resistentes à terapia e não mostraram reparo periapical após 12 meses de acompanhamento. Cirurgia periapical ou extração dental foi realizada. O teste de correlação indicou nenhuma correlação entre o número de colônias bacterianas e o tamanho da lesão (p=0.752, r=-0.148). Entretanto, uma maior colônia bacteriana geralmente resultou em uma maior lesão periapical (p=0.000, r=0.657). A frequência de actinomicose periapical foi baixa e esta lesão deve ser incluída no diagnóstico diferencial das LPs. O tamanho das colônias de Actinomyces pareceu contribuir para o aumento no tamanho da lesão periapical.

Presentación tumoral de actinomicosis pélvica / Tumor Presentation of Pelvic Actinomycosis

La actinomicosis es una enfermedad crónica granulomatosa poco común causada por bacterias gram positivas, anaeróbicas, microaerófilas principalmente del género Actynomices. Se presenta el caso de una mujer de 49 años de edad, con cuadro clínico de aproximadamente 4 meses de evolución dado por estreñimiento, asociado a tenesmo rectal durante la defecación y pérdida de peso, portadora de dispositivo intrauterino desde hace 7 años. En el examen físico se encontró la presencia de una masa, de bordes mal definidos, en flanco y fosa iliaca derechos, y en hipogastrio, no dolorosa a la palpación. El ultrasonido abdominal reportó una masa en lóbulo caudado hepático y una estructura de contornos mal definidos en íntimo contacto con techo vesical y fundus uterino. La biopsia de lesión reveló actinomicosis. Se confirma la actinomicosis en una paciente con masa palpable en hipogastrio y dispositivo intrauterino colocado(AU)

Actinomycosis is an uncommon granulomatous chronic disease caused by gram-positive, anaerobic, microaerophilic bacteria, mainly of the genus Actynomices. We present the case of a 49-year-old woman with a clinical condition of approximately 4 months of evolution due to constipation, associated with rectal tenesmus during defecation and weight loss, carrier of an intrauterine device for 7 years. In the physical examination, the presence of a mass was found, with poorly defined edges, flank anda iliac fossa right, and hypogastrium, not painful on palpation. Abdominal ultrasonography reported a mass in the hepatic caudate lobe and a structure of ill-defined contours in intimate contact with the bladder roof and uterine fundus. The lesion biopsy revealed actinomycosis. It was confirmed in a patient with palpable mass in hypogastrium and intrauterine device placed(AU)

Tuberculosis y actinomicosis: Un caso pediatrico de comorbilidad / Pulmonary actinomycosis and tuberculosis: A comorbidity pediatric case

La actinomicosis es una infección supurativa crónica, producida por bacterias Gram-positivas anaeróbicas o especies Actinomyces microaerófilas. Es rara en niños y adolescentes; es más común en inmunodeprimidos. El Mycobacterium tuberculosis colabora en el desarrollo de la enfermedad. La afectación pulmonar aparece como un cuadro de condensación crónica que no mejora con el tratamiento antibiótico convencional. Las complicaciones clásicas de afectación de la pared torácica con fistulización y supuración en «granulo de azufre¼ son descritas con menor frecuencia en la actualidad. El diagnóstico es un verdadero desafío y se establece mediante el aislamiento de las especies de Actinomyces. El tratamiento de elección para todas las formas clínicas de la enfermedad es el uso prolongado de antibióticos. Objetivo. Presentar un caso pediátrico de comorbilidad entre tuberculosis y actinomicosis. Resaltar la importancia de la sospecha diagnóstica de actinomicosis frente a todo proceso supurado crónico.

Actinomycosis is a chronic suppurative infection, produced by anaerobic Gram-positive bacteria or microaerobic Actinomyces species. It is rare in children and adolescents and it is more common in immunocompromised. Mycobacterium tuberculosis collaborates on the development of the disease. Pulmonary involvement appears as a picture of chronic condensation that does not improve with conventional antibiotic treatment. Classic complications affecting the thoracic wall with drainage in «sulfur granule¼ and fistulization are described less frequently nowadays. The diagnosis is a real challenge and it is set by using the isolation of species of Actinomyces. The treatment of choice for all clinical forms of the disease is the prolonged use of antibiotics. Objective: to present a pediatric case of comorbidity between tuberculosis and actinomycosis and to highlight the importance of diagnostic suspicion of actinomycosis in the presence of all chronic suppurative processes.

Actinomycosis affecting the spinal cord: a case report / Actinomicose comprometendo a medula espinhal: um relato de caso

Actinomycosis is a rare, chronic, suppurative, granulomatous infection caused by a group of gram-positive anaerobic bacteria belonging to the natural flora of the oral cavity and gastrointestinal and urogenital tracts. It may involve several organs. This case study refers to pulmonary actinomycosis with chest wall involvement and cord compression in a 29-year-old male who presented with fever, cough, hemoptysis, neck pain, and paresis and plegia of the lower limbs of 5-month duration.

A actinomicose é uma infecção rara, crônica, supurativa e granulomatosa, causada por um grupo de bactérias anaeróbias Gram-positivas que pertencem à flora natural da cavidade oral, do aparelho gastrointestinal e urogenital. Pode envolver diversos órgãos. O estudo refere-se à actinomicose pulmonar com envolvimento da parede torácica e compressão medular em um paciente masculino com 29 anos que apresentava febre, tosse, hemoptise e cervicalgia, além de paresia e plegia em membros inferiores com cinco meses de evolução.

Actinomicosis pulmonar: Diagnóstico por punción-aspiración con aguja fina / Pulmonary actinomycosis: Fine needle aspiration diagnostic

Se presentan 4 casos de actinomicosis pulmonar en pacientes mayores de 40 años, 2 de ellos con enfermedad pulmonar obstructiva crónica (EPOC), que mostraron un aumento de la tos productiva, episodios de disnea, hemoptisis y fiebre de larga evolución. En las radiografías de tórax de rutina se observaban imágenes segmentarias de consolidación aérea, sugestivas de cuadros neumónicos no resueltos o neoplasia. La tomografía axial computarizada (TAC) mostró hallazgos similares a los anteriores. Los cultivos de esputo y las pruebas de Mantoux fueron repetidamente negativos. Debido a la mala evolución de los pacientes y a los hallazgos radiológicos, se practicó una punción-aspiración con aguja fina (PAAF) para descartar neoplasia. En la citología se observaron conglomerados tridimensionales, de bordes filamentosos y aspecto algodonoso compatibles con Actinomyces. El tratamiento antibiótico produjo la mejoría del cuadro clínico y el seguimiento demostró la desaparición de las opacidades radiológicas. Actualmente, la actinomicosis pulmonar es infrecuente y la sintomatología inespecífica, por lo que puede confundirse con procesos neoplásicos. Por tanto, en pacientes con factores de riesgo, síntomas de neumonía subaguda e imágenes radiológicas de consolidación del parénquima es aconsejable considerar la posibilidad de actinomicosis pulmonar. Es una enfermedad tratable y su correcto diagnóstico mediante la PAAF evita al paciente pruebas diagnósticas más agresivas, retrasos en el diagnóstico y le permite una cura completa con tratamiento antibiótico.

We present four cases of pulmonary actinomycosis in patients over 40 years of age, two of them with chronic obstructive pulmonary disease (COPD), showing an increase in productive cough, episodes of dyspnea, hemoptysis and long-term fever. Routine chest radiographs revealed segmental air-space consolidation, suggestive of unresolved pneumonia or neoplasm. Computed tomography (CT) scan showed similar findings to the ones previously described. Sputum cultures for mycobacteriae and Mantoux tests were constantly negative. Due to the poor clinical and radiodological outcome of the patients, a fine needle aspiration (FNA) was made to rule out a neoplasm. Tridimensional filamentous colonies of Actinomyces were observed in cytology. Antibiotic treatment resulted in an improvement of symptoms. The follow-up showed a decrease of the consolidation areas. Pulmonary actinomycosis is rare nowadays and clinical symptoms are unspecific and can be confused with a neoplasm process. Therefore, in patients with risk factors, symptoms of subacute pneumonia and radiologic findings of consolidation, it is advisable to consider pulmonary actinomycosis as a diagnostic possibility. It is a treatable disease and its correct diagnosis by FNA, avoids performing invasive diagnostic tests, delays in the diagnosis and allows for a complete cure by antibiotic therapy.

A rare case of co-infection with pulmonary tuberculosis and oronasal actinomycosis / Caso raro de coinfecção tuberculose pulmonar e actinomicose oronasal

Oronasal actinomycosis is an infection seldom described in the literature, especially in the form of a co-infection with pulmonary tuberculosis. We report the case of a 48-year-old male admitted to the isolation ward due to active pulmonary tuberculosis, with a history of diabetes and alcohol abuse. While hospitalized, the patient complained of dysphagia and nasal regurgitation of food. The examination of the oral cavity revealed an oronasal fistula. The infecting agent was identified, and the treatment was successful. We also present a brief review of the literature, as well as a full description and discussion of the process of investigating this rare clinical case.

A actinomicose oronasal é uma infecção raramente descrita na literatura, especialmente na forma de coinfecção com tuberculose pulmonar. Descrevemos o caso de um paciente de 48 anos de idade, admitido em enfermaria de isolamento por tuberculose pulmonar bacilífera, com história de diabetes e alcoolismo. Durante a internação, o paciente referiu queixas de disfagia e regurgitação alimentar por via nasal. O exame da cavidade oral revelou uma fístula oronasal. O agente infeccioso foi identificado, e o tratamento foi realizado com sucesso. Apresentamos também uma breve revisão da literatura e uma descrição e discussão completa do processo de investigação deste raro caso clínico.

Pulmonary actinomycosis.

Pulmonary actinomycosis is rarely reported in pediatric age. An 11-year-old girl with history of two-month back pain was admitted to our hospital. On physical examination respiratory sounds were diminished on the left upper lung. Chest radiograph revealed a mass in the left upper lobe. Computed tomography showed solitary lesion (5.6 x 4.5 cm in size) in the left upper lobe. We could not rule out the possibility of malignant thoracic tumor. The patient underwent surgery. Histological examination of the resected tissue revealed, numerous sulfur granules, characteristic of Actinomyces, surrounded by purulent exudates, which are consistent with actinomycosis. She was treated with penicillin G. The patient responded well to penicillin therapy and the lesions regressed completely. She remained well throughout the three-year follow-up.

Epidemiología, resultados clínicos y costos del tratamiento del absceso tuboovárico, en un hospital público de Santiago / Epidemiology, clinical results and costs of treatment of the tuvoovarian abscess, in a public hospital in Santiago

Objetivos: Conocer frecuencia y factores de riesgo del absceso tuboovárico (ATO), complicaciones y costos del tratamiento. Método: Estudio retrospectivo de 64 pacientes operadas con el diagnóstico de ATO. Las pacientes se manejaron con criterio médico-quirúrgico: uso de antibióticos y cirugía en casos de peritonitis difusa, fiebre persistente con masa palpable y masa anexial mayor de 6 cm sin fiebre. Se evaluaron en fertilidad futura y en complicaciones: infección y dehiscencia de herida operatoria, reoperación por ATO residual, lesión intestinal, lesión vesical y complicaciones médicas. Resultados: El ATO representó el 73,6 por ciento de los casos hospitalizados por enfermedad inflamatoria pélvica, con frecuencia de 1,5 casos por mes y 17,2 por ciento de actinomicosis. La edad media de las pacientes fue 40,5 años. El dispositivo intrauterino (DIU) se asoció con ATO en 84,4 por ciento de los casos, 94,4 por ciento sin control y con media de uso de 10,2 años. El ATO unilateral fue el más frecuente (57,8 por ciento) y la anexectomía unilateral la operación más común. El 17,2 por ciento de las pacientes presentaron complicaciones y el 85,9 por ciento quedaron con infertilidad. El costo total de los 64 casos fue $86.331.713 (UF 3.788), con una media de $1.348.933 (UF 59,2). Conclusión: Existe un aumento de la frecuencia del ATO y de la actinomicosis pélvica, con incremento consiguiente de la infertilidad y de los costos, asociados al uso de DIU, sin control y por tiempo prolongado.

Objective: To determine frequency and risk factors of tuboovarian abscess (TOA) and observe complications, fertility damages and surgical costs of medical-surgical treatment. Method: Retrospective study in 64 patients operated with TOA diagnosis. Patients were managed with medical-surgical treatment: use of antibiotics and then surgery in cases of peritonitis diffuse, persistent fever with palpable mass and adnexial mass greater than 6 cm without fever. They were evaluated in future fertility and complications: infection and of surgical wound dehiscence, reoperation by residual TOA, intestinal injury, bladder injury and medical complications. Results: The TOA accounted for 73.6 percent of hospitalized cases of pelvic inflammatory disease (PID), 1.5 cases per month and 17.2 percent of actinomycosis. The mean age of patients was 40.5 years. The intrauterine device (IUD) was associated with TOA in 84.4 percent of cases, 94.4 percent uncontrolled and with a 10.2 years mean use. The unilateral TOA was the most frequent (57.8 percent) and the unilateral anexectomy the most common operation. The 17.2 percent of patients presented complications and 85.9 percent remained infertile. These results showed an increase compared with those obtained in the series published in 1993. The total cost of the 64 cases was $86.331.713 (UF 3.788), with a mean of $1.348.933 (UF 59.2). Conclusion: There is an increased frequency of the TOA and of pelvic actinomycosis, with consequent increase of infertility and costs associated with the uncontrolled and long-term use of IUD.

Abscesso cerebral por Actinomyces odontolyticus: relato de caso / Actinomycotic brain abscess: case report

Actinomicose é uma infecção supurativa crônica que tende a formar abscessos. O acometimento dos sistema nervoso central é evento raro, sendo crucial o diagnóstico diferencial com nocardiose para a seleção apropriada da terapia antimicrobiana. O manejo recomendado consiste na drenagem cirúrgica associada ao tratamento prolongado com antibióticos por, em média, 5 meses, além da erradicação do foco primário, quando identificado. Embora constitua uma forma tratável de abcesso cerebral causado por Actinomyces odontolyticus em paciente imunocompetente, cuja evolução desfavorável possa estar relacionanda à restrição do espectro antimicrobiano após identificação do agente etiológico.

Empiema por actinomyces: el gran simulador / Empyema due to Actinomyces: a diagnostic challenge

El derrame pleural aislado, como única manifestación de la actinomicosis es una situación muy rara y un desafío diagnóstico para el clínico, no sólo por su infrecuencia sino por la dificultad técnica para cultivar al gérmen. La típica apariencia microscópica de este bacilo Gram-positivo ramificado en los cultivos suele ser la clave del dianóstico. Se informa un caso de derrame pleural masivo izquierdo por Actinomyces israelii, sin afectación del parénquima pulmonar, de difícil diagnóstico, que mejoró clínica y radiológicamente en forma completa con el drenaje quirúrgico y tratamiento antibiótico prolongado.

Plasma Cell Granuloma Associated with Pulmonary Actinomycosis: A Case Report

Plasma cell granuloma (PCG) of the lung is a rare disease that usually presents as a pulmonary nodule or mass on incidental radiographic examination without symptoms. Although the etiology of PCG is still controversial, many findings have lent support to the lesion being a reactive inflammatory process rather than a neoplastic one. We describe a 53-yr-old male who presented with a hemoptysis and have a lung mass at the left upper lobe on chest radiograph. The lung mass was primarily diagnosed as PCG by percutaneous needle aspiration and biopsy, and the patient was treated with oral steroid because he and relatives refused the operation. However, the size of the lung mass did not change and open thoracotomy and lobectomy were done therefore. He was confirmed as having pulmonary actinomycosis with PCG after surgery. To our knowledge, this is the first report of PCG associated with actinomycosis in Korea.

Pulmonary actinomycosis presenting with prolonged fever and massive hemoptysis: a case report.

We present a rare case of pulmonary actinomycosis complicated with massive hemoptysis. The patient was a 41-year-old male farmer, who had experienced prolonged fever and off-and-on blood streaked sputum for 2 years. He was admitted to our hospital because of 3 days of massive hemoptysis. He had no underlying medical illnesses, but was a heavy smoker and an alcoholic. The chest radiograph revealed patchy alveolar infiltration of the right upper lobe, mimicing tuberculosis. Massive hemoptysis was not controlled using conservative treatment and anti-tuberculous drugs. Emergency right upper lobe lobectomy was needed to stop the bleeding. Histopathologic examination demonstrated aggregates of filamentous gram-positive organisms in characteristic "sulfur granules", indicating actinomycosis. The fever subsided after intravenous augmentin was given, followed by 6 months of oral amoxicillin. The patient is doing well and has had no recurrent hemoptysis.

Thoracic actinomycosis.

Thoracic actinomycosis represents about one-fourth of all cases of the disease. Isolated pleural effusion due to Actinomycosis is rare. We report a case of right sided pleural effusion with discharging sinus in the right anterior chest wall. Actinomycosis was suspected and confirmed by microscopic identification of "sulfur granules" in the discharge of the sinus tract and also identification of gram-positive filamentous bacteria in the specimen of discharging sinus. The patient improved clinically and radiologically after treatment with intravenous penicillin G followed by oral penicillin and aspiration of pleural fluid.

Mycotic Pulmonary Artery Aneurysm as an Unusual Complication of Thoracic Actinomycosis

Although pulmonary artery aneurysms are a rare vascular anomaly, they are seen in a wide variety of conditions, such as congenital heart disease, infection, trauma, pulmonary hypertension, cystic medial necrosis and generalized vasculitis. To our knowledge, mycotic aneurysms caused by pulmonary actinomycosis have not been reported in the radiologic literature. Herein, a case of pulmonary actinomycosis complicated by mycotic aneurysm is presented. On CT scans, this case showed focal aneurysmal dilatation of a peripheral pulmonary artery within necrotizing pneumonia of the right lower lobe, which was successfully treated with transcatheter embolization using wire coils.

Intra-abdominal actinomycosis presenting as complex abdominopelvic mass.

A rare case of intra-abdominal actinomycosis in a 70-year-old lady presenting as abdominopelvic mass mimicking malignancy is presented. Intra-abdominal actinomycosis may present a serious diagnostic problem both pre- and peroperatively and can lead to extensive surgical intervention due to the anticipation of malignancy. The diagnosis is difficult specially in the absence of characteristic discharging sinus. The diagnosis of this disease, potentially curable by antibiotic is more often made postoperatively by histopathology and microbiological methods.

Actinomycotic meningitis: report of a case.

A 73-year-old man who presented with acute fever, drowsiness and confusion was reported. Two weeks prior to admission, he attended the Outpatient Department with symptoms of fever and headache for 2 weeks. Eosiophilic meningitis was initially diagnosed, which, in fact, was lymphocytic CSF pleocytosis. He was treated with a high dose of prednisolone. His symptoms improved for 1 week, then he experienced symptoms of fever and headache again. On admission, he had stiffness of the neck. Lumbar puncture showed purulent CSF with gram-positive branching filamentous organisms. CSF grew Actinomyces israelii. The patient died from brain herniation.
