1/28. Atypical presentations of actinomycosis.BACKGROUND: Actinomycotic infections of the cervicofacial region are uncommon. Most major medical centers report approximately one case per year. Presenting clinical manifestations are confusing because they often mimic other disease processes. Diagnosis may be difficult due to a general lack of familiarity with the disease and the fastidious nature of the organism in culture. The cervicofacial manifestations of actinomycosis are varied, and a high index of suspicion is required to make an accurate and timely diagnosis. methods: Retrospective chart review with the presentation of four unusual cases of actinomycosis were performed. RESULTS: Two patients were initially seen with dysphagia from a tongue base mass. The third patient was initially seen with a 3-week history of worsening hoarseness and stridor. Examination revealed an ulcerative lesion of the left hemilarynx and pyriform sinus. All three patients were thought to have a neoplastic process. Diagnosis was made on histologic examination of a tissue biopsy. The fourth patient was initially seen with a buccal space mass that was draining externally. culture of the purulent drainage revealed actinomyces. In all four cases, symptoms resolved after appropriate antimicrobial therapy. CONCLUSIONS: actinomycosis of the head and neck, although rare, is an important entity to the otolaryngologist. A confusing clinical presentation combined with the fastidious nature of the organism make for a difficult diagnosis. A high index of suspicion is required to make an accurate diagnosis and institute the appropriate antibiotic therapy.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
2/28. Case report of regional alveolar bone actinomycosis: a juvenile periodontitis-like lesion.BACKGROUND: Cervicofacial actinomycosis infection most often involves the mandibular bone and rarely the alveolar crest. methods: We describe a 14-year-old patient who had actinomycosis involving the alveolar bone at the left lower dental quadrant region. Resembling juvenile periodontitis, it was difficult to diagnose properly and resulted in devastating dental and periodontal consequences: loss of one tooth with most of its adjacent regional alveolar bone, severely compromising the support of two other teeth. RESULTS: With the diagnosis came successful treatment, including surgical removal of the soft and hard tissues with concomitant prolonged penicillin administration. CONCLUSIONS: We feel that this case should raise the interest and concern of both the periodontist and the general practitioner so that early diagnosis can be obtained, significantly improving the clinical outcome.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
3/28. actinomycosis as a rare complication of orthognathic surgery.Modern orthognathic surgery is said to be clean contaminated due to the intraoral means of access. Complications after orthognathic surgery, a common operation, occur about 10% of the time. actinomycosis, a rare specific infection, plays a negligible role. Diagnostically, it should be differentiated from other infections that occur a long time after the operation. Three cases of actinomycosis that occurred after orthognathic surgery were observed, and therapeutic measurements are described case by case.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
4/28. Atypical presentations of pediatric actinomycosis: report of a case.It is well recognized that cervicofacial actinomycosis is rare in children, especially at maxilla. actinomycosis involving the maxilla usually is seen as a localized intraoral infection in contrast to classical cervicofacial actinomycosis. In this article, we describe an 8-year-old patient who had actinomycosis involving the bone at the left maxillary lateral incisor region. The diagnosis was based on histologic report because of location and development of the lesion with unusual history. The treatment of choice was removal of the soft and hard tissues with concomitant prolonged penicillin administration. In cases of persistent oral infection the diagnosis of actinomycosis should be actively attempted through microbiologic and histologic examination.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
5/28. 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 = infection (Clic here for more details about this article) |
6/28. 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 = 1keywords = infection (Clic here for more details about this article) |
7/28. Pediatric cervicofacial actinomycosis: a case report.Cervicofacial actinomycosis affects many soft tissue and bony structures in the head and neck, and has both granulomatous and suppurative features. Pathogenesis of actinomycosis is still unclear, but trauma provides a portal of entry for the infection. It usually presents as a diffuse swelling with multiple sinus tracts containing macroscopic colonies of the organism known as "sulphur granules." Cervicofacial actinomycosis in children is rare. This article reports a case of actinomycosis in a 10-year-old-boy overlying the left ramus of the mandible.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
8/28. Periapical actinomycosis: a review.actinomycosis has increasingly been recognized as a cause of persistent or recurrent periapical disease associated with endodontically treated teeth. This case report shows the classic clinical picture of periapical actinomycosis: persistent periapical disease with recurrent sinus tracts. Although there was no pain or swelling after clinically acceptable initial endodontic treatment, a periapical lesion developed. After retreatment, the periapical lesion persisted, and a sinus tract developed. The sinus tract healed with antibiotic therapy but recurred within a few months. This cycle of sinus tract to antibiotic therapy to recurrence of the sinus tract repeated several times over a period of 5 years. Upon biopsy, periapical actinomycosis was diagnosed, where classic "sulfur granules" were demonstrated in the histologic examination of the periapical lesion. Antibiotic therapy for a period of 6 weeks was prescribed subsequent to the histologic diagnosis because of the possibility of spread of the actinomycotic infection into the maxillary sinus. Considerable healing was evident within 5 months of surgical and antibiotic treatment.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
9/28. Intra-masseteric actinomycosis: report of a case.A case of actinomycosis arising within the masseter following extraction of a lower second molar is reported.

10/28. 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 = 47.377710789282keywords = bacterial infection, infection (Clic here for more details about this article) |
