Unusual aetiology of lymphocyte ‐predominant exudative pleural effusion: primary mediastinal actinomycosis

We report herein a case of mediastinal actinomycosis mimicking lung malignanc y presented with recurrent lymphocyte‐predominant pleural fluid exudate. In patients with a recurrent or unexplained exudative pleural effusion, it may be worthwhile to consider a hidden foci of actinomycosis.

Actinomycosis is a rare chronic granulomatous infection that requires a correlation of histopathologic and microbiologic findings for diagnosis. The case refers to a 52-year-old patient with a lesion in the anterior mandibular region after oral surgery. Clinical examination showed pain symptoms unresponsive to pain killers, prostration and numbness in the lip and chin regions, and a chest x-ray that revealed multiple nodules in the lung. The lesion presented erythema, edema, and granulomatous aspect that extended from tooth 32 to 45.

Although Actinomyces spp. are well-known oral commensals, actinomycosis is a rare oral infection. It is difficult to detect Actinomyces in biopsies, using histopathologic methods, or through examination of bacterial cultures; the...

We report a case of a 58 years old woman admitted to our institution for a pain of the right iliac fossa with a mass. The diagnosis was established after surgical intervention and histological examination. The treatment was surgical resection and antibiotherapy by amoxcillin during 6 months. The primary diagnosis of abdominal pelvic actinomycosis is difficult. All organs and anatomic structures of the abdomen can be involved. Even with extensive infection, combined operative and antibiotic therapy allows cure in most cases. PMID: 27100860 [PubMed - as supplied by publisher]

Discussion Actinomycosis is a rare and insidious disease. The most common etiologic organism is the anaerobic, Gram-positive bacterium, Actinomyces israelii. Actinomycetes are prominent among the normal flora of the oral cavity but less prominent in the lower gastrointestinal and female genital tract. Because these microorganisms are not virulent, they require a break in the integrity of the mucous membranes and the presence of devitalized tissue to invade deeper body structures and to cause human illness. Cervicofacial actinomycosis is the most common type of the infections followed by Thoracic actinomycosis and less comm...

CONCLUSIONS: Actinomycosis is a disease that must be considered by the surgeon when faced with a clinical picture of subacute onset with intermittent fever, weight loss, abdominal pain, and even anaemia in patients with abdominal and retroperitoneal abscesses or previous history of surgery.
