The etiology of infection in skin is commonly linked with a traumatic injury, human bite or a perforating injury, which creates an anaerobic environment for Actinomyces israelii to grow in ( J Clin Diagn Res. Colon nontumor - Actinomycosis. Due to infection by anaerobic or microaerophilic, saprophytic bacteria of genus Actinomyces, a normal commensal of mouth, large intestine, vagina ; Disruption of mucosa is necessary for disease - causes are trauma, surgery, diverticular disease, ingestion of foreign body, or less commonly other inflammatory processe
Primary perianal actinomycosis is rare. Sporadic cases, with lesions varying in extent have been reported. The infection is caused by the bacterium Actinomyces, which often is a saprophyte. Male gender and diabetes are risk factors, but the exact pathogenic mechanism remains speculative. The diagnos 30100 Telegraph Road, Suite 408, Bingham Farms, Michigan 48025 (USA Actinomycosis is a subacute-to-chronic bacterial infection caused by filamentous, gram-positive, non-acid-fast, anaerobic-to-microaerophilic bacteria. It is characterized by contiguous spread, suppurative and granulomatous inflammation, and formation of multiple abscesses and sinus tracts that may discharge sulfur granules The disease was originally discovered by Otto Bollinger in 1870, and its name was coined by Sebastiano Rivolta in 1884. The name refers to its grape-like granules (Greek: botryo = grapes) and the mistakenly implied fungal etiology (Greek: mykes = fungus) In 1919 the bacterial origin of the infection was discovered
Hepatic actinomycosis is an uncommon entity that forms communicating abscesses and fistulae. A case is presented in which findings on ultrasound, CT, and percutaneous injection of the abscess all reflected the pathologic process. Biopsy by thin-needle aspiration under CT guidance afforded prompt, ac Etiology. Primary abscesses may arise due to disruption of ovarian capsule, as in ovulation or surgical intervention (vaginal hysterectomy, ovarian cystectomy, caesarean section, pregnancy, use of intrauterine device, transvaginal or percutaneous needle aspiration of endometrioma or follicle aspiration as part of in vitro fertilization, Tunis. Actinomycosis of the head-and-neck region is a significant entity because it can mimic other common lesions especially in the oropharynx. In cases of recurrent tonsillitis and tonsillar hypertrophy, tonsillectomy is the treatment of choice and histopathological examination of resected tissue is strongly advocated.

Discussion. Canaliculitis is a disease which is most commonly thought to be associated with yellow, gritty concretions secondary to Actinomyces species. As mentioned previously, the classic histopathology in Actinomyces-related infection reveals basophilic masses with an eosinophilic periphery and a background of Gram-positive, filamentous bacteria [1-3] Abdominal actinomycosis has been recognised for over 150 years yet remains largely unknown to most clinicians.It's varied presentations are usually considered to represent malignancy rather than an infective process - and was once described as 'the most misdiagnosed disease'.Actinomyces are gram positive bacilli of the Actinomycetales genus, and A. israelii is responsible for the.
Actinomyces israelii is a commensal organism of the oral cavity so the rounded aggregates of Actinomyces organisms seen above in tonsillar crypts are not pathogenic. The aggregates can also be seen in the setting of clinical infection, particularly in purulent material (pus) draining from abscesses, where they are large enough to be seen. Sarcoidosis is a chronic granulomatous disease of unknown etiology and is characterized by the presence of noncaseating granulomas in the involved tissues. There is often multi system involvement typically with prominent pulmonary and cutaneous findings, as well as involvement of the liver, spleen, and various locations in the head and neck 1.

2. Discussion. Gastric actinomycosis is a rare clinical condition with only 25 cases reported to date. It is a chronic suppurative infection caused by the anaerobic Gram-positive filamentous bacteria Actinomyces, usually Actinomyces israelii.1, 2. The rarity of gastric involvement by actinomycosis has been attributed to the high lumenal acidity of the stomach which inhibits bacterial growth In cervical smears, follicular cervicitis is detected by areas with lymphoid cels of different sizes and, in rare zones, elements suggesting centro-follicular structures.

It most commonly affects women of reproductive age and nearly 60% of women with TOA are nulliparous. 1 TOA is defined as an inflammatory mass involving the tube and/or ovary characterised by the presence of pus. The most common cause is ascending/upper genital tract.

Thus, definitive diagnosis of actinomycotic granules (AMGs) in gynaecological specimens is clinically important. Non-infectious pseudoactinomycotic radiate granules (PAMRAGs) can mimic the microscopic appearance of AMGs Epidemiology .

BACKGROUND Pelvic-abdominal actinomycosis is a rare chronic condition caused by an anaerobic, gram-negative rod-shaped commensal bacterium of the Actinomyces species. When Actinomyces becomes pathogenic, it frequently causes a chronic infection with granulomatous abscess formation with pus. Due to d Actinomycosis is a chronic suppurative granulomatous bacterial infection caused by Actinomyces israelii, which is a slow growing, filamentous, gram positive, non-spore forming anaerobic, or microaerophilic bacteria. Actinomyces species are usually found in human oropharynx, gastrointestinal tract, vagina, and they grow slowly with conditions of. Pelvic actinomycosis comprises a rare, subacute to chronic bacterial infection characterised by suppurative and granulomatous inflammation. Diagnosis is difficult as it may simulate pelvic malignancies. Laboratory and radiological findings are non-specific. We reported on 2 cases of pelvic actinomycosis mimicking ovarian malignancy with different management approaches that lead to opposite. Prognosis, in general, seems to be good, as far as the urinary tract is concerned. CASE REPORT P. J.
