We report a case of a 60-year-old Saudi woman who developed tracheoesophageal fistula and fatal pulmonary infection secondary to thoracic actinomycosis. The cause, clinical presentation, radiological features and treatment of thoracic actinomycosis are discussed.

Pulmonary actinomycosis is a rare pulmonary infection that often exhibits unspecific symptoms and radiological findings. We herein report a case of pulmonary actinomycosis that mimicked pulmonary aspergilloma in an immunocompetent patient.

Cervicofacial actinomycosis is today a rare disease in our country. Isolated neck swelling due to actinomycosis is extremely rare. A case of 52 year old man with an isolated neck swelling due to actinomycosis without any discharging sinus is reported here.

The diagnosis and treatment of abdominal actinomycosis is difficult. We report a case of chronic diverticulitis of the sigmoid colon with stricture formation and obstruction, which was complicated by intramural actinomycosis. We suggest that diverticular strictures and actinomycosis may coexist more often than the literature suggests.

Actinomycosis is a rare chronic granulomatous infection caused by Gram-positive, non-acid-fast, anaerobic to microaerophilic bacteria.We report a case of cervicofacial actinomycosis in an 86-year-old woman undergoing immunosuppressive therapy with azathioprine and prednisone for rheumatoid arthritis. She underwent a dental treatment several months earlier. The diagnosis of culture-negative acti...

Pelvic actinomycosis comprises a rare, subacute to chronic bacterial infection characterised by suppurative and granulomatous inflammation. Diagnosis is difficult as it may simulate pelvic malignancies. Laboratory and radiological findings are non-specific. We reported on 2 cases of pelvic actinomycosis mimicking ovarian malignancy with different management approaches that lead to opposite outc...

Actinomycosis is a chronic, suppurative, and granulomatous process caused by Actinomycetes, saprophytic bacteria normally residing in the oral cavity. It can involve any organ, but the cervicofacial disease is the most frequent. Pharyngolayngeal involvement is rare and usually occurs secondary to the oral or cervical disease. There are few cases of primary pharyngolaringeal actinomycosis descri...

Actinomycosis is occasionally an opportunistic infection occurrence in patients with osteoradionecrosis (ORN). A retrospective study (1992-97) of 50 patients with ORN of the jaws was done to evaluate the incidence and its clinical significance in the management of ORN. Actinomycosis was diagnosed in 12% of ORN cases. In 36 of the 50 patients including five cases of actinomycosis, the ORN was co...

caused by the Gram-positive anaerobic filamentous bacterium, Actinomyces Israeli. Actinomycosis involving the urachal remnant is extremely rare and can mimic urachal carcinoma or other infectious conditions (1, 2). Because of the nonspecific clinical presentation, the diagnosis of urachal actinomycosis is usually made by surgery followed by a histopathologic examination. The radiologic findings...

Actinomycosis is a rare, chronic, suppurative and granulomatous disease caused by Actinomyces israelii, which is a filamentous, anaerobic, gram-positive, saprophytic organism in the oral cavity. Diagnosis of actinomycosis depends on positive culture or identification of Actinomyces colonies and sulfur granules in histological specimens. In our case, a mass had been growing in the mandible for e...
