“…There have been a few reports describing the characteristics of pleural or pericardial fluid caused by actinomycosis, which differ in the cellular distributions. For example, Coodley and Yoshinaka reported a case of lymphocyte‐predominant exudate, as in this present case , while another study showed polymorphonuclear leucocyte‐predominant exudates .…”

Actinomycosis is a rare infectious bacterial disease typically involving cervicofacial, abdominopelvic, or thoracic regions, caused by Actinomyces species. However, involvement of the mediastinum as the primary site of origin is extremely rare. An elderly patient complained of left‐sided chest pain. The chest radiograph revealed pleural effusion, which revealed lymphocyte‐predominant exudates. Chest computed tomography showed a soft tissue mass in the left anterior mediastinum. Positron emission tomography revealed an increased uptake of 18F‐fluorodeoxyglucose in this lesion. To exclude malignancy and make a confirmative diagnosis, a mediastinal biopsy was performed through video‐assisted thoracic surgery. Finally, mediastinal actinomycosis was diagnosed. We report herein a case of mediastinal actinomycosis mimicking lung malignancy 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.

A combination of surgical and antimicrobial therapy may carry a fair-to-good prognosis for thoracic granuloma caused by actinomycosis (arcanobacteriosis) or nocardiosis. The extent of surgery should be based on assessment of individual cases and must include surgical biopsy for histology and culture to enable a specific diagnosis to be made. Complete surgical excision is not necessarily required. Prolonged antimicrobial therapy is indicated.

Actinomycosis is caused by gram-positive filamentous organisms of the genus Actinomyces, which may spread through trauma. Most commonly, it is a cervicofacial disease due to dental infection or a thoracic disease secondary to aspiration of foreign bodies. Primary abdominal infection usually follows some form of mucosal disruption. Any organ of the human body may be involved so that a wide range of symptoms may be present. We report a rare form of actinomycosis involving the lung, pleura and colon concomitantly in an immunocompromised patient. A fine needle aspiration from a lung lesion detected the characteristic sulfur granules, and a pleural effusion culture confirmed the diagnosis. Clinical manifestations and treatment are discussed. Actinomycetes are rarely opportunistic agents in immunocompromised patients; thus the disease deserves special attention in those patients.
