The anatomic structure resembles actinomycosis and mycetoma, and its granules resemble the sulfur granules of actinomycosis It is usually described in individuals with impaired immunity or with an underlying disease such as diabetes mellitus, cystic fibrosis or HIV infectio Sulfur granules in pus are seen in_____? Sulfur granules in pus are seen in_____? A. Candida albicans B. Actinomyces israelii C. Nocarda braziliances Oral Pathology and Medicine Multiple Choice Questions (MCQ) for entrance examinations and other competitive examinations for all Experienced, Freshers and Students Typically form pink/purple granules (sulfur granule) that is surrounded by inflammatory cells (lymphocytes or neutrophils) Actinomycosis abscesses grow larger as the disease progresses, often over months. In severe cases, they may penetrate the surrounding bone and muscle to the skin, where they break open and leak large amounts of pus, which often contains characteristic granules (sulfur granules) filled with progeny bacteria
Microscopic observation of the bacteria in the sulfur granules is a presumptive diagnosis of actinomycosis. A unique feature of actinomycosis is that the expanding lesion can cross normal anatomic barriers, such as the fascial plane between muscles or tissues (Whitworth and Jacobs, 2014) The Sulphur granules are actually conglomeration of filamentous gram positive bacilli trapped in a biofilm like material. These are seen in the center of suppurative inflammation. These bacilli are bordered by eosinophilic amorphous material with club shaped configuration. This is referred to as Splendore-Hoeppli reaction
Open biopsy or fine-needle aspiration can be used to provide material for diagnosis. 2 A presumptive diagnosis can be made by identifying sulfur granules on a hematoxylin-eosin slide. 1-8 The actinomycotic lesion presents as an isolated mass of inflammatory response with a central area of suppurative necrosis, which contains multiple granules The diagnosis is mainly based on stereotaxic aspiration of pus, revealing Actinomyces spp. in cultures and sulfur granules in pathology. 1-3,82-84. Current and emerging treatment options. The treatment of actinomycosis brain abscess requires prolonged antimicrobial therapy after pus aspiration. 1-3,82-84. Cutaneous actinomycosi Incisional biopsy can assist to a large extent the diagnosis of actinomycosis. The typical findings include the presence of sulfur granules seen as basophilic masses with a granular center and a radiating fringe of club-shaped protrusions as well as the distinctive filamentous and beaded actinomyces Although the presence of sulfur granules is considered pathognomonic for actinomyces, there are other species of Gram positive filamentous bacteria present in the oral cavity and gynaecological tract; thus, culture is recommended for definitive diagnosis Morris, Zhiheng Pei, Liying Yang; Chronic Tonsillar Hypertrophy Is Related To Sulfur Granules, American Journal of Clinical Pathology, Volume 138, Issue suppl_2, 1 November [academic.oup.com] Since this anaerobic organism is difficult to culture, the diagnosis is made by observing its associated sulfur granules in the biopsy specimen

On surgical pathology, actinomycosis is characterized by sulfur granules (Figure 1). These are composed of bacteria cemented together by a polysaccharide-protein complex and calcium phosphate. Grossly, these sulfur granules appear yellow

The patient underwent surgical exci- sion and pathology revealed Actinomyces flora with sulfur granules on hematoxylin and eosin staining (Fig. 2). After the operation, the patient was prescribed an oral form of amoxicillin 500 mg to be taken 3 times daily for 2 months. At the 1-year follow- up, the patient was healthy and there was no sign of.

However, we were able to make the correct diagnosis by confirming the presence of sulfur granules on pathology examination. If there are atypical clinical findings or unexpected operative findings, we recommend culture, gram staining, Tb PCR, and pathologic examination The chronic granulomatous lesions usually become suppurative and frequently form draining sinus tracts that may contain small, hard, pale yellow 'sulfur granules' containing the organism. Microscopic observation of the bacteria in the sulfur granules is a presumptive diagnosis of actinomycosis Finding characteristic organisms by pathology or by staining of sulfur granules may not give a species level diagnosis, but can be quick and easy as compared to culture. In practice, this is often how the infection is diagnosed. Actinomyces can be easily gram stained The sulfur granules, which are named for their yellow color, represent tangled filaments of Actinomyces species . Those granules are comprised of bacterial elements and tissue debris ( 4 ). With hematoxylin-eosin staining, sulfur granules are seen as round, oval, or horseshoe-shaped basophilic masses with a radiating fringe of eosinophilic. Histologically, the bacteria are easily recognizable on hematoxylin-eosin-stained sections, as the organisms conglomerate to form the so-called sulfur granules, which appear as radiating rosettes (see Figures 2 and 3). The sulfur granules found inside the abscess cavity are characterized by round to oval masses with eosinophilic spokes, also.

Actinomycetes has a unique feature, pus in this infection has a yellow color due to the presence of sulfur granules. That's it for now The gross and microscopic features are described. As the diagnosis of this potentially serious infection is usually made by the histologic demonstration of sparsely distributed sulfur granules, the pathologist should approach every case of IUD-associated pelvic inflammation with a high index of suspicion. PMID: 920661 [PubMed - indexed for MEDLINE Sulfur granules (SGs) in tonsillar crypts are large clusters of bacteria that have drawn the attention of many physicians since 1896. I was taught that the granules represent actinomycosis when I was a medical student and learned to diagnose tonsillar actinomycosis during my residency in pathology
ACTINOMYCOSIS 1. DR AMITHA G, BDS, MDS ORAL AND MAXILLOFACIAL PATHOLOGY Actinomyces species are classified as anaerobic, gram positive and filamentous bacteria. It is a chronic granulomatous suppurative and fibrosing disease caused by anaerobic or microaerophilic gram-positive nonacid fast, branched filamentous bacteria. Most of the species isolated from actinomycotic lesions have been. a liver abscess. Microbiological analyses from both sites were negative. Shortly after surgical exploration, she developed multiorgan failure and died. At autopsy, pus was observed both within the pericardial cavity and around the left lobe of the liver. Green sulfur granules suggestive of infection with Actinomyces spp. were able to be extruded from the liver during the postmortem. Multifocally adhered to (and adjacent to) the grass awn there are large colonies of basophilic filamentous 1 x 3-7 µm bacteria admixed with finely granular basophilic material (sulfur granules). The grass awn and colonies of filamentous bacteria are surrounded by areas of drop-out with scattered eosinophilic and cellular debris and loss of. These 3 cases were detected by sulfur granules and histology. Pathologic signs included pymetra containing pus with sulfur granules, branching of actinomyces, chronic inflammation of the bilateral fallopian tubes and ovaries, liquefaction necrosis, and tubo-ovarian abscesses . A patient with actinomyces infection of the posterior neck was diagnosed by fine-needle aspiration biopsy. The lesion presented as a recurrent, firm, and indurated mass that was clinically diagnosed as adenitis and cellulitis and was thought to be a lymphoma 6 months after the onset of his illness
Pathological evaluation of the pleura showed sulfur granules and organisms consistent with Actinomyces spp. on Gomori methenamine silver stain; Actinomyces israelii was recovered in culture with extended incubation. The patient was treated for 3 weeks with ceftriaxone and oral metronidazole, followed by oral amoxicillin These colonies are known as sulfur granules because in gross specimens they are visible to the naked eye as yellow grains, thus resembling grains of sulfur. This is a higher-power photomicrograph of an abscess demonstrating a pocket of purulent exudate that contains numerous actinomycotic colonies (arrows)
