We report a rare case of lung abscess due to Eubacterium brachy. In this case, an analysis of the aspirate from frank pus revealed Gram-positive coccobacilli. We initially strongly suspected lung abscess associated with actinomycosis because of the chronic/recurrent clinical course and radio-pathological findings such as a granuloma lesion. Although a biochemical analysis revealed Actinomyces s...

Actinomycosis is an infection caused by the actinomyces genus and is associated with trauma or previous infection. A 58-year-old male patient was referred from a private dental clinic for root extraction of the lower right molar. The x-ray showed fractured root-like material distal to the distal root of the lower right second molar. A biopsy during extraction of the root-like material was perfo...

Actinomycosis is a subacute or chronic suppurative bacterial infection caused by filamentous gram positive, anaerobic to microaerophilic non acid fast bacilli primarily of the genus Actinomyces that normally colonize the mouth, colon and vagina. Primary cutaneous actinomycosis is a rare entity and is generally associated with trauma. We report a case of primary cutaneous actinomycosis of the ba...

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...

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...

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...
