UNLABELLED INTRODUCTION Primary hepatic actinomycosis is a rare disease, but is important in the differential diagnosis of hepatoma in endemic areas. As high mobility group box chromosomal protein 1 plays an important role in the pathogenesis of both acute and chronic inflammatory conditions, we postulate that high mobility group box chromosomal protein 1 may have a possible pathogenic role ...

Actinomycotic infections of the cervicofacial region are not uncommon. However, actinomycosis of the tongue is rare. A mass that may mimic both benign and malignant neoplasms can be seen at clinical presentation and may mislead the diagnosis. We report a patient who presented with a tumour-like tongue mass causing speech disturbance, diagnosed as actinomycosis.

We report a case of actinomycosis presenting as a knee swelling in a 34 year-old man. Knee actinomycosis poses a diagnosis challenge to clinicians as it is rare, often mimics knee tuberculosis and culture of the causative microbes is technically difficult. The classic microscopic appearance of this Gram-positive bacteria often forms the basis of diagnosis.

Actinomycosis is a rare heterogeneous anaerobic infection with misleading clinical presentations that delay diagnosis. A significant number of misdiagnosed cases have been reported in specific localizations, but studies including various forms of actinomycosis have rarely been published.We performed a multicenter retrospective chart review of laboratory-confirmed actinomycosis cases from Januar...

Actinomycosis is rarely accompanied by fungus balls. It difficult to distinguish between actinomycosis and a ball due their similar clinical computed tomography scan results. Thus, meticulous histopathological examination required for definite diagnosis. We report case of ball, found incidentally in patient without rhinologic symptoms. The was successfully treated with endoscopic sinus surgery,...

Actinomycosis is an indolent, slowly progressive, suppurative infection caused by gram-positive branching bacteria of the genus Actinomyces. The organism is a part of the oral and gastrointestinal microflora of humans. The most common parts of body involved in actinomycosis are cervicofacial (55% of patients), abdominopelvic (20%) and pulmonothoracic (15%). Involvement of other parts of the bod...

BACKGROUND Pelvic actinomycosis is uncommon and often presents as a complication of an intrauterine device (IUD). A diagnosis of actinomycosis can be made from the finding of sulfur granules within inflammatory exudate on histologic examination after surgery. However, it may be possible to diagnose actinomycosis before surgery by finding Actinomyces-like organisms on Papanicolaou smears. CASE...

BACKGROUND Thoracic actinomycosis is an uncommon, chronic suppurative bacterial infection caused by actinomyces species, especially Actinomyces israelii. METHODS It is usually seen in immunocompetent patients with respiratory disorders, poor oral hygiene, alcoholism and chronic debilitating diseases. RESULTS We illustrate the radiological manifestations of thoracic actinomycoses in various ...

Actinomycosis is a rare and chronic infectious disease caused by a non-spore gram- positive, anaerobic bacterium that rarely infects the colon, in particular the left colon. A 53-year-old woman was referred to us due to chronic abdominal pain, bloating, a few episodes of bloody-mucous rectal discharge, and change of bowel habits. Her medical history and physical examination were unremarkable. C...

An 80-year-old man was admitted to our hospital with a diagnosis of primary hepatic actinomycosis determined based on a percutaneous aspiration biopsy. The abscesses and state of liquefaction were easily and effectively visualized on contrast-enhanced ultrasonography. Ampicillin/sulbactam was administered; however, lesions of hepatic actinomycosis suddenly infiltrated the diaphragm and right th...
