1/6. Rare lesions of the oral cavity: case report of an actinomycotic lesion limited to the gingiva.actinomycosis is an infectious disease that frequently has chronic granulomatous and suppurative lesions caused by saprophytic actinomyces species. Although cervicofacial actinomycosis is known to be the most common type, intraorally and periodontally types occur rarely in a localized fashion. The present case reports on an adult periodontitis patient with a diffuse and atypic actinomycotic lesion which was limited to the gingiva and had an abscess formation, a large desquamation and subsequent exposure of the alveolar bone in the involved region. diagnosis was based on histopathological examination, the history of the case and clinical nature of the lesion. The patient responded to daily administration of 100 g doxcycycline (first day-bid) for 3 weeks and 0.2% chlorhexidine gluconate irrigation (following tooth brushing) performed with oral hygiene reinforcement and periodontal debridement procedures. Complete improvement of the lesion was observed after 5 weeks. Due to the opportunistic characteristics of the actinomycotic infection, early and adequate differential diagnosis of actinomycosis prior to therapeutic attempts, as well as management steps, are of great importance in the oral cavity to prevent the spread of the disease.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/6. actinomycosis of the masseter muscle: report of a case and review of the literature.A rare case of cervicofacial actinomycosis arising primarily in the masseter muscle is described. The patient was a healthy 74-year-old woman who was not immunocompromised and had no other primary pathological finding in the oral cavity. The importance of the differential diagnosis for this unusual infection is demonstrated with tumoral pathological findings. Possible predisposing factors as well as diagnostic and therapeutic methods are discussed.- - - - - - - - - - ranking = 0.2keywords = oral cavity, cavity (Clic here for more details about this article) |
3/6. scalp actinomycosis mimicking soft tissue mass.actinomycosis is a rare, subacute or chronic bacterial infection, characterized by localized swelling with suppuration, abscess formation, tissue fibrosis, and draining sinuses. It is caused by gram-positive, pleomorphic non-spore-forming, non-acid-fast anaerobic or microaerophilic bacilli of the genus actinomyces. In humans, actinomyces are often normally found in the oral cavity, the gastrointestinal tract and the female genital tract. Infections of the oral and cervicofacial regions are the most commonly reported cases. We present a case of subcutaneous actinomycosis, localized at the upper segment of the posterior neck space, with scalp involvement.- - - - - - - - - - ranking = 0.2keywords = oral cavity, cavity (Clic here for more details about this article) |
4/6. Acute cervico-facial actinomycosis.Cervico-facial actinomycosis still occurs occasionally and should be included in the differential diagnosis of infectious processes in the jaws and the oral cavity. The typical actinomycosis-cases are clinically chronic in nature; however actinomycosis may be atypical with subacute or acute clinical manifestations. Among 37 cases of infectious processes in the jaws treated with extraoral incision between 1980 and 1985 in the Department of Oral Surgery, School of Dental medicine, University of Berne, 3 (8%) were diagnosed as acute actinomycosis according to the following procedure. Prior to incision, pus was aspired under aseptic conditions. Presence of gram-positive branched filaments in the microscopically examined pus led to the suspicion of actinomycosis. This diagnosis was confirmed by cultivation of actinomyces israelii using the anaerobic culture method, biochemical characteristics and gas-liquid chromatographic analysis of metabolic products. These 3 actinomycosis-cases were successfully treated by surgical removal of the suspicious foci and by administration of clindamycin per os for 16 days.- - - - - - - - - - ranking = 0.2keywords = oral cavity, cavity (Clic here for more details about this article) |
5/6. Localized oral blastomycosis mimicking actinomycosis.A case of blastomycosis limited to the oral cavity is presented. The disease apparently originated in the mandible and eroded into the oral cavity. Secondary bacterial infection of the sinus tracts resulted in a clinical picture that mimicked cervicofacial actinomycosis. Appropriate microbiologic studies, including culture confirmation of the causative organism, were necessary to establish a definitive diagnosis.- - - - - - - - - - ranking = 0.4keywords = oral cavity, cavity (Clic here for more details about this article) |
6/6. actinomycosis of the vallecula: report of a case and review of the literature.A rare case of actinomycosis presenting primarily as a mass in the vallecula is described. The patient was a healthy, 65-year-old Saudi, lady who was not immunocompromised and had no other primary pathology in the oral cavity. The clinical presentation and management of the case are discussed and the relevant literature reviewed.- - - - - - - - - - ranking = 0.2keywords = oral cavity, cavity (Clic here for more details about this article) |
