The authors describe a case of advanced thoracic actinomycosis. A 44-year-old man with previous episodes of productive cough with purulent sputum, fever, chest pain and subcutaneous nodules on the left hemithorax was admitted with complaints of lumbar pain irradiating into left lower limb and presence of mass lesion on the left lumbar region. Imaging evaluations were obtained and the patient un...

background: actinomycosis is an indolent, slowly progressive infection caused by non acid fast, gram positive, anaerobic or microaerophilic bacteria. the most common site of actinomycosis infection is cervicofacial region. bacteriologic identification from infected site or detection of sulfur granules confirms the diagnosis. we report a rare case of simultaneous infection of larynx and lungs ac...

CHEST I 103 I 6 I JUNE, 1993 1887 Pulmonary actinomycosis usually occurs as a result of the aspiration of oropharyngeal material in the setting of poor dental hygiene or oral trauma. When pathogenic, it is invasive, often mimicking a malignancy in presentation and macroscopic appearance. Endobronchial disease due to this pathogen rarely is reported. Ariel et al recently described five patients ...

A 51-year-old woman visited our hospital with massive hemoptysis. She had suffered from recurrent hemoptysis for five years and had undergone bronchial artery embolization many times. The patient had a history of pulmonary tuberculosis and bronchiectasis. Chest radiography showed consolidation around the nodule in the lateral basal segment of the right lower lobe. We successfully performed a ri...

Eradication of a cause of secondary membranous glomerulopathy might suppress nephrotic syndrome. Here we report a patient with membranous nephropathy (MN), whose proteinuria entered complete remission after treating actinomycosis. A 45-year-old woman presented with nephrotic syndrome and was diagnosed as having MN. Her urine protein excretion was 5.3 g/day and the serum creatinine level was 70....

We describe a case of actinomycosis of the gallbladder mimicking carcinoma. Sonography showed a hypoechoic mass replacing gallbladder lumen and engulfing a stone; contrast-enhanced computed tomography showed a heterogeneously enhanced thickened gallbladder wall with subtle, disrupted luminal surface enhancement, which formed a mass. As a result of the clinical and radiologic presentation, our i...

BACKGROUND Primary actinomycosis of the anterior abdominal wall and appendix are very rare clinical entities. An accurate diagnosis is generally obtained by histological examination, and treatment often requires surgical resection. CASE REPORT In this study we presented two cases of primary actinomycosis involving the anterior abdominal wall and a third one located in the appendix. CONCLUSI...

introduction: actinomycosis is a systemic chronic bacterial infection caused by actinomyces israelii, an anaerobic organism normally resident in the human mouth. however, the actinomycosis of the larynx is very rare, and only about 15 cases have been reported in the literature so far. most of the cases reported occurred in patients who had previously undergone radiotherapy for laryngeal cancer....

Sinonasal actinomycosis should be suspected when a patient with chronic sinusitis does not respond to medical therapy or has a history of facial trauma, dental disease, cancer, immunodeficiency, long-term steroid therapy, diabetes, or malnutrition. Radiological evaluation with computed tomography and magnetic resonance imaging are important in differential diagnosis, evaluating the extent of di...

BACKGROUND Actinomyces is a bacterial rod found in the normal oral flora. It can gain entry to the submucosa via trivial wounds and ultimately lead to slow growing lesions which may mimic cancerous lesions. METHODS AND RESULTS We present the case of an elderly, immunosuppressed woman who presented with a herald bleed from a tonsillar lesion. Despite initial operative arrest of the hemorrhage,...
