BMJ Case Rep 2020 May 27;13(5). Epub 2020 May 27.

Oral and Maxillofacial Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, USA

Cervicofacial actinomycosis remains a rare pathogenic finding in the paediatric population. Diagnosis is challenging, as findings are often non-specific and species are generally difficult to culture. Treatment is a prolonged course of antibiotics, either intravenous and oral, often combined with a surgical procedure to remove the lesion. Read More

Disseminated Actinomycosis A Rare Cause of Abdominal Pain: A Case Report.

Oman Med J 2020 Mar 30;35(2):e117. Epub 2020 Apr 30.

Department of Pathology, Salmaniya Medical Complex, Manama, Bahrain.

Abdominal pain is a common clinical presentation that can be caused by a variety of conditions ranging from self-limited to serious pathologies. It may be the first symptom of an occult malignancy, especially in elderly patients or in the presence of systemic manifestations such as weight loss, fever, fatigue, and anorexia. However, functional gastrointestinal disorders, vascular pathologies, renal diseases, genitourinary illnesses, and chronic infections should also be considered as possible causes of abdominal pain.

Members of the genus are non-spore-forming, anaerobic, and aerotolerant Gram-positive bacteria that are abundantly found in the oropharynx. They are the causative agents of actinomycosis, a slowly progressing (indolent) infection with non-specific symptoms in its initial phase, and a clinical course of extensive tissue destruction if left untreated. Actinomycoses are considered to be rare; however, reliable epidemiological data on their prevalence is lacking. Read More

Actinomycosis is an uncommon, endogenous, and chronic infection with varied and nonspecific clinical features such as abdominal, pelvic or cervical masses, ulcerative lesions, abscesses, draining fistula, fibrosis, and constitutional symptoms. The disease ensues when the bacteria disrupt the mucosal barrier, invade, and spread throughout interfascial planes. Currently, the diagnosis of actinomycosis is challenging because of its very low frequency and depending on the clinical presentation it may masquerade malignancies. Read More

Submandibular gland actinomycosis: A rare disease - Worth to mention.

J Oral Maxillofac Pathol 2019 Sep-Dec;23(3):479

Department of Otorhinolaryngology, All India Institute of Medical Sciences, Jodhpur, Rajasthan, India.

Cervicofacial actinomycosis (AM) is a well-documented entity; however, primary AM of the submandibular gland is infrequent. The diagnosis is difficult due to its nonspecific clinical presentation and it usually mimics chronic granulomatous infection or malignant lesion. We report the case of a young female with AM of submandibular gland, presented as recurrent infection of submandibular gland, underwent its excision and confirmed on microscopy as . Read More

Abdominal actinomycosis in an elderly diabetic.

Pak J Med Sci 2020 Jan;36(1):S98-S100

Nausheen Yaqoob, MBBS, FCPS. Consultant and Head of Section of Histopathology, The Indus Hospital, Karachi, Pakistan.

Actinomycosis is a rare infectious disease that presents as three entities, cervico-facial, abdominal and genital, with cervico-facial being the commonest. Due to its subacute presentation and indolent course, abdominal actinomycosis is difficult to diagnose and is often confused with malignancy. We present a case of an elderly diabetic with no known other risk factors of the disease with complaints of right sided abdominal swelling and presence of abdominal mass on imaging, diagnosed post operatively as a case of abdominal actinomycosis, on histopathology.

Image screening for maxillo-mandibular actinomycosis with CT, F-FDG-PET/CT, and F-α-methyl tyrosine PET/CT.

Oral Radiol 2020 Jan 10. Epub 2020 Jan 10.

Department of Oral and Maxillofacial Surgery and Plastic Surgery, Gunma University Graduate School of Medicine, 3-39-22 Shouwamachi, Maebashi City, Gunma, 371-8511, Japan.

Objectives: Clinical features and imaging findings of maxillo-mandibular actinomycosis are similar to those of intraosseous carcinoma. The purpose of this study is to clarify the characteristics of the imaging findings for screening of maxillo-mandibular actinomycosis using CT and PET.

Methods: Reports on maxillo-mandibular actinomycosis published between 1997 and 2016 were searched in PubMed using "actinomycosis," "maxilla," and "mandibular" as keywords. Read More

Insufficient initial treatment but good recovery after diagnosis of pulmonary actinomycosis.

Oxf Med Case Reports 2019 Dec 31;2019(12):510-512. Epub 2019 Dec 31.

Division of Internal Medicine, Department of Internal Medicine, Chitose City Hospital, Chitose, Hokkaido 066-8550, Japan.

Actinomycosis is an infrequent invasive bacterial disease. Although multiple different clinical features of actinomycosis have been described, pulmonary actinomycosis (PA) is a rare but challenging diagnosis and complete cure to make. Here we report the case of a 41-year-old Asian woman who had a mass-like consolidation in the right middle lung field. Read More

Don't Let Its Name Fool You: Relapsing Thoracic Actinomycosis Caused by Pseudopropionibacterium propionicum (Formerly Propionibacterium propionicum).

Am J Case Rep 2019 Dec 29;20:1961-1965. Epub 2019 Dec 29.

Department of Internal Medicine, University of Iowa Carver College of Medicine, Iowa City, IA, USA.

BACKGROUND Pseudopropionibacterium propionicum was called Propionibacterium propionicum until a recent taxonomy change in 2016. Diseases caused by P. propionicum resemble actinomycosis and thus differ dramatically from the infectious syndromes caused by common cutaneous Propionibacterium spp. Read More

Clinicopathological and ultrastructural characterization of periapical actinomycosis.

Med Oral Patol Oral Cir Bucal 2020 01 1;25(1):e131-e136. Epub 2020 Jan 1.

Background: The aim of the present study was to analyze the clinicopathological and the ultrastructural features of periapical actinomycosis (PA) cases.

Material And Methods: Data from the files of an oral pathology laboratory were retrieved and the findings of histopathological analysis were evaluated. Hematoxylin-eosin (HE), a modified Brown & Brenn, and Grocott stains as well as ultrastructural analysis using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) were utilized.

Department of Critical Care Medicine, University of Calgary, Calgary, AB, Canada.

Background: Whipple's disease is a clinically relevant multi-system disorder that is often undiagnosed given its elusive nature. We present an atypical case of Whipple's disease involving pan-valvular endocarditis and constrictive pericarditis, requiring cardiac intervention. A literature review was also performed assessing the prevalence of atypical cases of Whipple's disease. Read More
