1/16. Diffuse chronic sclerosing osteomyelitis and the synovitis, acne, pustolosis, hyperostosis, osteitis (SAPHO) syndrome in two sisters.Two sisters with diffuse chronic sclerosing osteomyelitis of the mandible and the humerus and the synovitis, acne, pustolosis, hyperostosis and osteitis syndrome (SAPHO syndrome) are presented. The diagnoses of diffuse chronic sclerosing osteomyelitis at the age of 12 years and 27 years, respectively, were based on typical medical history, clinical symptoms and radiographic, histologic and scintigraphic findings. Because skin lesions and scintigraphic enhancement of the sternoclavicular joints with hyperostosis were present, a SAPHO syndrome was diagnosed in both sisters. Microbiological cultures of biopsy specimens revealed coagulase-negative staphylococcus aureus at the humerus and haemophilus parainfluenzae, Streptococcus, actinomyces and Veilonella species at the mandible. Repeated operative procedures, including decortications, resection and reconstruction, and multiple histologic and microbiologic studies were performed over a period of up to 20 years. Since HLA typing yielded identical gene loci, we suggest that hereditary and autoimmune factors may play a role in the pathogenesis of these cases.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/16. An unusual form of actinomycosis of the mandible with a resultant gross sequester in a 4-year-old child: a case report.Mandibular osteomyelitis due to actinomyces group is considered rare in the pediatric population. The initial complaint of the 4-year-old child described here was increased swelling of his cheek and pain. The patient was managed successfully by surgical treatment with antibiotic therapy.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
3/16. False diagnosis caused by Warthin tumor of the parotid gland combined with actinomycosis.A case is reported in which a unilateral parotid gland cystadenolymphoma was combined with actinomycosis. A 48-year-old woman presented with a mass in the left parotid region and paresis of the lower left palpebra. The computed tomography, echography, and parotid radiographic findings did not exclude a neoplasm of the left parotid gland. The ramus of the mandible was involved in the process. Intraoperative freezing histology, total parotidectomy, and partial mandibulectomy were performed, with sacrifice of the facial nerve followed by nerve reconstruction. The final histological evaluation was Warthin tumor with actinomycosis. Four years after treatment, the patient is free of disease. No similar cases seem to have been reported thus far.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
4/16. Oral metastasis of breast carcinoma diagnosed by fine needle aspiration cytology. A case report.BACKGROUND: Fine needle aspiration cytology (FNAC) is an important technique in the diagnosis of oral and maxillofacial conditions. The purpose of the present paper is to report a case of oral metastasis of breast carcinoma diagnosed by FNAC. CASE: A 45-year-old, black woman was referred for evaluation of symptomatic swelling in the left mandible. The medical history revealed that the patient had undergone extensive surgery to remove a lobular carcinoma. She had finished chemotherapy treatment about 5 months earlier. Due to the main diagnostic considerations of metastatic and inflammatory disease, FNAC was performed. The cytologic picture was consistent with a metastatic glandular neoplasm. CONCLUSION: FNAC is a safe, reliable, cost-effective and easy procedure and sometimes eliminates the need for open biopsy.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
5/16. actinomycosis of the middle turbinate: an unusual cause of nasal obstruction.actinomycosis is a rare chronic infectious disease caused by actinomyces israelii, which is an anaerobic filamentous, gram-positive saprophyte organism of the oral cavity. Historically, these bacteria were known as fungi because of their light microscopic appearance. actinomycosis consists of three different forms: cervico-facial (the most common form), abdominal and pulmonothoracic. It commonly involves the head and neck region including the mandible, paranasal sinuses, lacrimal gland, parotid gland and orbit. Poor oral hygiene and dental diseases have been known to be the source of actinomycosis. actinomycosis is diagnosed with positive culture or detecting actinomyces colonies and sulfur granules in histopathologic specimens. The treatment of choice is surgical excision of the lesion and long-term penicillin therapy. actinomycosis of the internal nose is extremely rare. There was only one nasal septum actinomycosis reported in the English literature, but there was no lateral nasal wall actiomycosis regarding the turbinate. Therefore, actinomycosis should not be overlooked for the differential diagnosis of intra-nasal lesions for the initiation of appropriate and early treatment.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
6/16. actinomycosis presenting as osteomyelitis in the pediatric population.osteomyelitis attributable to actinomyces often results in recurrent disease and inconsistent responses to antimicrobial agents. We present data for 4 patients and a review of the 15 previously described pediatric cases of actinomycosis presenting as osteomyelitis. Fourteen cases involved the mandible and 5 cases involved other sites. All mandibular cases required at least 1 debridement, with 4 of the cases requiring multiple debridements.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
7/16. actinomycosis complicating fibula flap mandible reconstruction: a report of two cases.Two patients undergoing fibula flap mandible reconstruction developed chronic intraoral wounds and salivary fistulae. After initial attempts at salvage, tissue biopsies demonstrated actinomycosis infection. With antibiotic treatment and debridement, one reconstruction was salvaged while one was lost. actinomycosis infection should be considered a possible agent in chronic wounds complicating mandible reconstructions with microsurgical flaps.- - - - - - - - - - ranking = 3keywords = mandible (Clic here for more details about this article) |
8/16. Unusual parotid tumors.The patient presenting with a mass lesion of the parotid gland is frequently found to have a mixed tumor of salivary tissue origin. However, less common lesions occur in the anatomical region of the parotid gland. These pathological entities deserve consideration in the differential diagnosis. This report presents nine patients with unusual lesions occurring in the parotid region. These regions include cervicofacial actinomycosis, branchial cleft cyst, parapharyngeal tumors, bony lesion of the mandible, non-parotid origin malignant tumor, and metastatic malignant tumors. Each class of lesions demonstrated is also discussed.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
9/16. Cerebral botryomycosis: case study.After oral surgery, a 32-year-old man developed a brain abscess. actinomycosis was suspected due to history, clinical findings, response to penicillin therapy, and demonstration of "sulfur granules" in the surgical specimen, but anaerobic cultures were negative for actinomyces. Aerobic cultures yielded streptococcus sanguis and pseudomonas cepacia. Coccoid organisms demonstrated histologically reacted positively with periodic acid-Schiff, Gomori's methenamine silver, and Brown and Brenn stains, were Ziehl-Neelsen-negative, and did not include branching filaments. Fluorescent antibody assay for actinomyces israelii was also negative. Electron microscopy revealed cell wall morphology and pattern of cell division characteristic of gram-positive cocci. These findings led to a final diagnosis of botromycosis due to S. sanguis. This third report of cerebral botryomycosis emphasizes the differential diagnosis with actinomycosis, the association with intermittently treated jaw disease, and identification of the causative agent by histologic, immunologic, and electron microscopic methods.- - - - - - - - - - ranking = 0.10943077600911keywords = jaw (Clic here for more details about this article) |
10/16. 'Punch' actinomycosis causing osteomyelitis of the hand.Osseous actinomycosis usually results from direct invasion of bone from adjacent soft-tissue infection. Involvement of the jaw and vertebral column has been frequently reported, but involvement of the bones of the wrist or hand is rare. A patient with osteomyelitis of the distal right first metacarpal bone due to actinomyces israelii following a punch injury during fisticuffs is described. review of similar cases revealed a striking association of this type of infection with punch injuries; hence the term, punch actinomycosis. Analysis of the pus in these infections typically reveals sulfur granules; strict anaerobic conditions must be employed to culture the etiologic agent, A israelii. Management of individual cases should include surgical debridement combined with high-dose parenteral penicillin, followed by long-term penicillin therapy, orally.- - - - - - - - - - ranking = 0.10943077600911keywords = jaw (Clic here for more details about this article) |
