Actinomycosis has been rarely reported in patients with HIV/AIDS in contrast to other opportunistic and common pathogens. We report a case of esophageal ulcer disease, secondary to actinomycosis occurring in a patient with recurrent odynophagia. The diagnosis was made histologically only after repeated upper endoscopy with biopsies.

Actinomycosis is a very rare cause of orbital abscess usually attributable to direct spread from adjacent structures. A case of actinomycosis of the orbit is presented, which was treated as orbital pseudotumour for 3 months before progression of signs and symptoms, despite high dose steroids, led to the diagnosis being reconsidered.

Actinomycosis is a rare inflammatory disease caused by Actinomyces israelii. It can mimic many other diseases, such as malignant neoplasms or inflammatory bowel disease. We present a case in which actinomycosis simulated a colonic neoplasia.

Actinomycosis is rare compared to carcinoma, but the two conditions can present with very similar clinical pictures. Two cases of actinomycosis are reported, one thoracic and one pelvic-abdominal which presented as carcinoma and proceeded to surgery without a histological diagnosis having been established.

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. ...

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...
