Actinomycosis was once a fairly common disease and one that has a long history . "It was undoubtedly observed early in the 19th Century, as actinomycotic lesions were described erroneously in 1826 by LeBlanc as osteosarcomas and later in the 1800s Bollinger (1876) first recognized it as a specific entity which he named 'lumpy jaw.' " 1 The most frequent clinical form of actinomycosis is the cer...

BACKGROUND AND PURPOSE Actinomycosis is an uncommon and frequently misdiagnosed infection that may present as an acute or indolent process. Even when clinical suspicion is high, the disease is commonly confused with other chronic inflammatory diseases and malignancy. An early diagnosis helps the clinician in deciding treatment and can avoid physical morbidity such as unwarranted surgery. METH...

INTRODUCTION Actinomycosis is an uncommon chronic granulomatous infection first described by Bollinger in 1 877.The infection is caused by actinomyces species and it is characterized by slow contiguous spread and suppurative inflammation, formation of multiple abscesses and sinus tracts with possible drainage of "sulfur granules". CASE OUTLINE We report an unusual case of actinomycosis of the...

Nasopharyngeal actinomycosis is a rarely encountered bacterial infection which usually occurs after nasal trauma or surgery. In some clinical cases, nasopharyngeal actinomycosis has appeared in patients without prior trauma, making diagnosis difficult. Here we present three such cases successfully treated with appropriate dosages of penicillin. One 16-year-old boy with no previous medical antec...

INTRODUCTION Actinomyces are slow growing, non-spore forming, gram-positive, branching bacilli that thrive in anaerobic and microareophilic conditions. Actinomyces are more commonly associated with oral and cervicofacial infections. Hepatic involvement in infections of the abdomen (known as isolated hepatic actinomycosis) is rare, accounting for only 5% of all cases of actinomycosis. CASE PRE...

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,...
