1/7. Oral papillary plasmacytosis resembling candidosis without demonstrable fungus in lesional tissue.Two cases with exuberant papillary and nodular hyperplasia of the hard and soft palates are described. Both were elderly edentulous men with bilateral angular stomatitis. The papillary hyperplasia extended as far as the epiglottis and was associated with swelling and fissuring of the upper lip in patient 1. In patient 2, the palatal change extended to the maxillary gingiva and was associated with smooth plaques and fissuring of the dorsal tongue. histology of both cases showed a dense polyclonal plasma-cell infiltrate with overlying epithelial hyperplasia, parakeratinization and neutrophil micro-abscesses suggesting Candida infection but fungal elements could not be demonstrated. Patient 1 also showed defective cellular immunity to Candida antigen which was reversed by treatment with ketoconazole and levamisole, antedating clinical improvement.- - - - - - - - - - ranking = 1keywords = fungus (Clic here for more details about this article) |
2/7. Pulmonary nocardiosis associated with primary nocardial infection of the oral cavity.A case of pulmonary nocardiosis associated with primary nocardial infection of the oral cavity in a compromised host is presented. nocardia asteroides, an aerobic, gram-positive, branching, filamentous fungus, was demonstrated in the sputum and in pathologic specimens from gingival sulci stained by Gram's method and the acid-fast method Kinyoun. The organism was identified in cultures made on Sabouraud's glucose agar. Marked clinical improvement was noted when the patient received high dosage of sulfisoxazole diolamine (8 to 12 Gm. per day) for a prolonged period of time (9 to 12 months). Because of an apparent relative increase in the incidence of nocardiosis and a paucity of information on the subject in the dental literature, this article is timely.- - - - - - - - - - ranking = 0.25keywords = fungus (Clic here for more details about this article) |
3/7. candida glabrata (syn. Torulopsis glabrata) associated with a chronic hyperplastic lesion of the palate.A case initially presenting as chronic hyperplastic candidosis is described. After treatment with nystatin on three separate occasions over a seven-year period, a lesion similar to that diagnosed originally occurred in the same site. Further examination of this later occurrence showed it to be associated with the imperfect fungus candida glabrata which had a high minimum inhibitory concentration for nystatin (greater than 30 micrograms/ml). The lesion eventually resolved following treatment with miconazole gel and surgical excision of the hyperplastic tissue. The patient has remained symptomless for a two-year follow-up period.- - - - - - - - - - ranking = 0.25keywords = fungus (Clic here for more details about this article) |
4/7. Persistent, painful ulcerations of the hard palate and buccal mucosa.C albicans is an opportunistic fungus that produces infection almost exclusively in debilitated or immunocompromised people. The importance of the recognition of candidiasis is not only in the prompt institution of appropriate therapy but also in the identification and treatment of underlying systemic disease. The high rate of occurrence of candidiasis in patients with AIDS or ARC, often as the first symptom, is of significance to the dental practitioner, who may be the first health professional to see such patients.- - - - - - - - - - ranking = 0.25keywords = fungus (Clic here for more details about this article) |
5/7. epiglottitis in immunocompromised patients.Modern medical oncology has made dramatic improvements in the prognosis of many malignancies. Many of the treatment regimens used by the chemotherapist have the potential to profoundly depress the immune system. At UCLA Medical Center, three patients developed epiglottitis secondary to the fungus candida albicans, while profoundly immunocompromised. All three had severe pain and odynophagia. The patients were all managed medically and none went on to airway obstruction. The natural history of this process is reviewed.- - - - - - - - - - ranking = 0.25keywords = fungus (Clic here for more details about this article) |
6/7. Torulopsis glabrata infection in the oral cavity.The first case report of an oral infection due to Torulopsis glabrata is presented. This microorganism is a yeast-like fungus grouped in a similar family to the Candida species. It has been isolated with increasing frequency from the oral cavity but, surprisingly, has not been reported as a pathogen in this site. In other anatomical sites, including the urinary tract, lung and gastrointestinal tract, Torulopsis glabrata has been reported as a pathogen, at times resulting in a fatal outcome. However, there has usually been some modifying factor, e.g. malignancy, cytotoxic drug therapy, diabetes or broad spectrum antibiotics, which caused this marginal pathogen to assume a pathogenic role. No such modifying factors could be elicited in this case. The history of the case including the management is presented. A brief outline of the microbiologic grouping of Torulopsis glabrata is given, as well as the diagnostic test used in its identification. The histopathology is described and the necessity for combining special tests in establishing a positive diagnosis is exemplified, as the histology alone is not pathognomonic of the infection.- - - - - - - - - - ranking = 0.25keywords = fungus (Clic here for more details about this article) |
7/7. mucormycosis of the oral cavity.mucormycosis (phycomycosis, zygomycosis) is an acute opportunistic infection caused by a saprophytic fungus found in soil, bread molds, and decaying fruits and vegetables. Numerous predisposing risk factors are associated with mucormycosis, although most cases have been reported in poorly controlled diabetics or in patients with hematologic malignant conditions. This report presents two cases of oral mucormycosis. One case occurred in the maxilla in a patient with well-controlled diabetes. The other involved the mandible and overlying gingiva in a patient with acute myelogenous leukemia. A review of the literature concerning oral mucormycosis is also presented.- - - - - - - - - - ranking = 0.25keywords = fungus (Clic here for more details about this article) |
