Actinomycosis is an infectious disease caused by certain Actinomyces species. Actinomyces are Gram-positive, non-spore forming organisms characterized by obligate or facultative anaerobic rods that normally inhabit anaerobic niches of the human oral cavity. Cervicofacial, abdominal, pelvic and thoracic infections of Actinomyces are not uncommon, but endobronchial actinomycosis is rarely reporte...

Actinomycosis is a chronic, opportunistic infection caused by Actinomyces species, such as Actinomyces bacillus. Actinomycosis in long bones is very rare. To the best of our knowledge, isolated primary actinomycosis of the humerus is rarely reported in literature. We present a rare case of a refractory primary actinomycosis of the humerus. A 66-year-old man with no history of concomitant condit...

PURPOSE Actinomycosis is an uncommon chronic granulomatous disease that presents as a slowly progressive, indolent, indurated infiltration with multiple abscesses, fistulas, and sinuses. The purpose of this article is to report on a case of actinomycosis with clinical findings similar to periodontitis. METHODS A 46-year-old female presented with recurrent throbbing pain on the right first and...

Actinomycosis is a chronic suppurative infection, for which immune suppression is a predisposing factor. In unusual cases, this disease may present as an abdominal wall involvement simulating a soft tissue tumor as seen in the present case. The presented patient had no signs of trauma or surgical approach and the pathology was considered to be a primary abdominal wall actinomycosis. Preoperativ...

Actinomycosis is a rare and slowly progressive infectious disease that can affect a variety of organ systems including the lung. It is caused by filamentous Gram-positive anaerobic bacteria of the genus Actinomyces. Despite its rarity, pulmonary actinomycosis can involve lung parenchyma, bronchial structures, and chest wall. The disease can mimic lung malignancy given its nonspecific clinical a...

Rationale: Osteoma with actinomycosis is a very rare disease in the nasal cavity. Patient concerns:We report a case of a 17-year-old female student who presented with nasal obstruction and rhinorrhea for 6 months. Diagnoses: The preoperative finding was osteoma covered with yellowish polypoid material. Interventions:We performed endoscopic sinus surgery, which included excision of the tumor and...

A 30-year-old Chinese lady was admitted for hoarseness of voice of one month's duration. Clinical examination revealed a granuloma of the left vocal cord while chest X-ray showed an opacity in the lower lobe of the right lung. The provisional clinical diagnosis was tuberculous laryngitis. A biopsy of the vocal cord lesion revealed inflamed tissue with actinomycotic colonies. Cultures and sputum...

Actinomycosis is a rare disorder caused by an anaerobic gram-positive bacillus (Actinomyces), predominantly by the Actinomyces israelii species. Only 20% of cases show an abdominal manifestation, the appendix and ileocecal valve being the most frequent locations. Definitive diagnosis is based on microbiological cultures, microscopy or macroscopy examination. Nevertheless, histological examinati...

Pelvic actinomycosis is an uncommon, slowly progressing granulomatous infection that has been associated with the presence of intrauterine devices. Due to its unspecific clinical and radiologic findings, it can mimic pelvic or intra-abdominal malignancy leading to mutilating surgery of high morbidity. Rarely, diagnosis is made preoperatively and in most cases surgical intervention is necessary....

Abdominal actinomycosis may appear as an abdominal mass and/or abscess. This mass can mimic a malignant tumour. The diagnosis and management of abdominal actinomycosis will be discussed through a review of the literature and a case report from our own institution. The patient was a 17-year-old boy who presented with abdominal discomfort and a palpable right lower quadrant mass defined on CT sca...
