It is a sporadic but common disease in cattle, occasional in pigs and horses and rarely in goats (Radostits et al., 2007). Members of the genus Actinomyces are Gram positive, non-acid fast, non-spore forming rods (Songer and Post, 2005) that form a mycelium of branching filaments that fragment into irregular-sized rods (Blood et al., 2007). The species that commonly cause disease in domestic animals include A. bovis, A. hordeovulneris, A. hyovaginalis, A. israelii, A. naeslundii, A. suis, A. viscosus and Arcanobacterium pyogenes (Songer and Post, 2005). Actinomyces bovis is a common inhabitant of the bovine mouth and infection is presumed to occur through wounds to the buccal mucosa caused by sharp pieces of feed or foreign material. Infection may also occur through dental alveoli, and may account for the more common occurrence of the disease in young cattle when the teeth are erupting (Radostits et al., 2007). Actinomyces viscosus causes periodontal disease and subgingival plaques in hamsters fed a high carbohydrate diet, and also abscessation in dogs (Timoney et al., 1988) in which it is an opportunistic infection (Blood et al., 2007).

Anaerobic bacteria have been implicated in a wide range of infectious processes from almost all anatomical sites, by bacteria from both exogenous (e.g., toxin-mediated pathologies by Clostridia) and endoge- nous (displacement of the bacterial flora to other anatomical regions) sources [2]. These pathogens may be important etiological agents in life-threatening, invasive infections [3,4].

We report a case of paravertebral TB abscess and miliary TB in a 17-year-old male initially presenting with fever, general weakness, back pain, sweating, cough, dyspnea and weight loss. The patient was diagnosed as paravertebral TB abscess and miliary TB. The anti-tuberculous drugs were started and the follow-up imaging showed that the lesions had disappeared without surgery.

Ulcers may develop spontaneously or following a penetrating injury. wounds not healing well are common among poor, lower middle class and middle class people. Postsurgical non-healing wound or chronic discharging sinuses at the scar site are also common in that class of people. Suspecting malignancy or tuberculosis in these types of wounds we have sent wedge or excision biopsy for these ulcers in about 500 cases and found tuberculosis in 65 cases. In rest of the cases histopathology reports found as non- specific ulcers, Malignant melanoma, squamous or basal cell carcinoma, Verruca vulgaris. Objectives: To find out the relationship of tuberculosis with chronic or nonhealing ulcers. Methods: This is a prospective observational study conducted for patients coming to our chambers, OPD of a district general hospital and Shaheed Suhrawardy Medical College Hospital, Dhaka from July 2012 to June 2018. Results: Mean age of the study subjects were 28±2. Among the study subjects nonspecific ulcer or sinus tracts were found in 418 (83.6%), tuberculosis in 65 (13%), Malignant melanoma 7 (1.4%), Verruca vulgaris 5(1%), squamous cell carcinoma 3(0.6), basal cell carcinoma 2 (0.4%).

Abstract Actinomycosis is a chronic, suppurative granulomatous inflammation caused by Actinomyces israelli which is a gram positive organism that is a normal commensal in humans. Multiple clinical features of actinomycosis have been described, as various anatomical sites can be affected. It most commonly affects the head and neck (50%). In any site, actinomycosis frequently mimics malignancy, tuberculosis or nocardiosis. Physicians must be aware of clinical presentations but also that actinomycosis mimicking malignancy. In most cases, diagnosis is often possible after surgical exploration. Following the confirmation of diagnosis, antimicrobial therapy with high doses of Penicillin G or Amoxicillin is required. This article is intended to review the clinical presentations, histopathology and complications of actinomycosis in various sites of the body.

Scrofuloderma is the most common variant of cutaneous tuberculosis, which is characterized by a direct extension of the skin which overlies the infected lymph gland, bone or joint, that breaks down to form an undermined ulcer.

The clinical diagnosis may present serious difficulties because of its ability to mimic other lesions, including both benign and malignant neoplasms. Methods: Here, we describe the case of a 52-years-old patient affected by an asymptomatic, tumor-like tongue swelling, then diagnosed as actinomycosis. A review of tongue localization of actinomycosis is also reported, with emphasis on clinical findings and therapy. Results and Conclusion: Early diagnosis and treatment, with pus drainage and systemic antibiotic therapy, are pivotal to avoid severe and life-threatening complications.
