Actinomycosis is an uncommon disease in children and most cases are cervicofacial infections. To date, there have been only a few reports on children with chest wall involvement due to actinomycosis. Here we report a 9-year-old girl with a mass lesion in the chest wall mimicking Ewing's sarcoma of the rib. Thoracic actinomycosis without typical features of the disease is often evaluated with th...

Actinomycosis is a bacterial infection due to Actinomyces israelii, a gram-positive, anaerobic organism that normally affects the cervicofacial region. However, facial injury or trauma (i.e., dental procedures) can allow this bacteria to inhabit other regions. There have been rare reports of actinomycosis of the paranasal sinuses. We present a case of a 50-year-old female who originally present...

Pelvic actinomycosis is an uncommon disease in humans. It has nonspecific and variable clinical features, and thus it is difficult to diagnose. Moreover, appropriate management is delayed or overlooked because it can sometimes simulate advanced ovarian cancer. We report a case of pelvic actinomycosis which manifested with hydronephrosis and bowel stricture, lymph node enlargement and increased ...

A 40-year-old man presented recurrent cough and bloody sputum for 4 months. Chest X-ray showed a large mass in the right upper lobe. Histopathologic examination of tissue from percutaneous biopsy of the lesion revealed actinomycotic granules and branching filamentous bacteria, and therefore pulmonary actinomycosis was diagnosed. These findings suggest that pulmonary actinomycosis should be incl...

Thoracic actinomycosis is a well described entity. The clinical spectrum is broad, ranging from the asymptomatic patient with an abnormality on chest radiography to the chronically ill patient with fever, weight loss, and skin lesions from sinus tracts draining a lung abscess. Here we report a more unusual presentation, a patient with a chest wall lesion and right handed weakness found to be se...

Most textbooks of paediatrics consider actinomycosis a rare infection in children and few collective studies or case reports in children have been reported. Pyogenic infection of the chest is common in Malaya and Singapore, but there has been no recorded case of actinomycosis in children so far, and it is because of the rarity of the condition that it is felt worth while to report these two cas...

We report the imaging and pathologic findings of fishbone-associated actinomycosis of the anterior cervical space in a 57-year-old man, misdiagnosed preoperatively as a malignancy originating from thyroglossal duct cyst. CT revealed an enhancing mass containing a small abscess pocket and two sharp linear calcifications within it, which infiltrated into the strap muscle. Pathologic examination d...

We report a case of unusual presentation of actinomycosis in the tonsil causing massive unilateral enlargement in a 78-year-old female. To our knowledge, only three cases of actinomycosis causing unilateral tonsillar enlargement have previously been published. Since this anaerobic organism is difficult to culture, the diagnosis is made by observing its associated sulfur granules in the biopsy s...

Background Bacteria of the genus Actinomyces that colonize the oral cavity rarely cause infection. Fifty-percent of the cases of actinomycosis are in the cervicofacial area, more common in male patients and in infants. In most of cases, the onset of the disease occurs on the teeth or tonsils. Early diagnosis of cervicofacial actinomycosis has been reported in less than 10% of cases. The aim of ...

Actinomycosis is a rare, chronic, suppurative, granulomatous infection caused by a group of gram-positive anaerobic bacteria belonging to the natural flora of the oral cavity and gastrointestinal and urogenital tracts. It may involve several organs. This case study refers to pulmonary actinomycosis with chest wall involvement and cord compression in a 29-year-old male who presented with fever, ...
