OBJECTIVES Actinomycosis is a chronic suppurative granulomatous infection caused by the Actinomyces genus. Orocervicofacial actinomycosis is the most common form of the disease, seen in up to 55% of cases. All forms of actinomycosis are treated with high doses of intravenous penicillin G over two to six weeks, followed by oral penicillin V. Large studies on cervicofacial actinomycosis are lacki...

Actinomyces species has been described as an opportunistic pathogen, particularly in the oral cavity; however, in rare cases these bacteria can cause actinomycosis which is characterized by formation of abscesses in the mouth, lungs, or gastrointestinal tract. Actinomycosis was commonly present in the pre-antibiotic era; however, it has a low prevalence now days. It has been recognized since 15...

Actinomycosis is a chronic, suppurative, and granulomatous process caused by actinomycetes, saprophytic bacteria normally residing in the oral cavity. There are a few cases of primary actinomycosis described in the literature where it can involve any organ. We present a rare case of an actinomycosis in a 69 year old man, with swelling over posterior compartment of thigh for 6 months, mimicking ...

BACKGROUND Actinomycosis is a rare inflammatory disease caused by an anaerobic bacterium that can rarely affect the large intestine. CASE PRESENTATION We present a rare case of a cecum and ascending colon actinomycosis in a 72 years old woman, mimicking clinically a malignant inflammatory tumor of the right colon. The patient complained of right lower quadrant pain. Although our first thought...

Actinomycosis is a rare, chronic granulomatous infection caused by gram-positive, anaerobic to microaerophilic branching filamentous bacteria. In the cervicofacial region, it usually presents as an enlarging neck mass. It remains a diagnostic challenge due to the fact that cultures show no growth in more than 50% of cases. We report a case of a 67-year-old patient known to have a neck mass seco...

Human actinomycosis is a bacterial infection caused primarily by Actinomyces israelii, a resident of the oral cavity. The cervicofacial region is most commonly affected; thoracic and abdominal forms of the disease have also been distinguished. Actinomycosis is sometimes difficult to diagnose and it should be borne in mind in the differential diagnosis of numerous infectious and non-infectious d...

Actinomycosis, a rather uncommon infection of the oral cavity, poses and unusual problem: recurrence. Primary or initial diagnosis of the disease is difficult and can be made easier only if the clinician bears in mind a few important facts: a previously compromised site is usually present, a slow, low-grade, almost painless infectious course is prevalent which tends to localize, and respond...

actinomycosis can involve all parts of the urogenital system. urachal actinomycosis rarely reported and was mistaken with urachal adenocarcinoma. we report a case of urachal actinomycosis that presented with abdominal pain and underwent laparotomy with the diagnosis of urachal malignancy pathology reviewed the diagnosis of urachal actinomycosis. patient had no problem in two years follow up.

Actinomycosis is a chronic suppurative bacterial infection characterized by multiple abscesses, fistulous pathways, and fibrosis involving the face, neck, chest, and abdomen. It is caused by an anaerobic Gram-positive saprophytic bacterium (Actinomyces). Primary actinomycosis of the lung is a rare disease that probably results from aspiration of oropharyngeal secretions. It can present as a chr...

CONTEXT Chronic alcoholic pancreatitis is a debilitating disease that is often complicated by pseudotumoral changes of the pancreas, retroperitoneal fibrosis, and pancreatic cancer. Actinomycosis is an uncommon intra-abdominal infection and its association with chronic pancreatitis has been rarely reported. CASE REPORT We present a case of a patient with progressive long standing chronic panc...
