1/35. lidocaine toxicity during frequent viscous lidocaine use for painful tongue ulcer.Oral viscous lidocaine is useful for the treatment of symptoms induced by oral inflamed mucosa, such as radiation- or chemotherapy-induced mucositis. The toxic reactions associated with an accidental overdose have been reported in pediatric cases. We report a case of lidocaine toxicity in a 22-year-old man during frequent viscous lidocaine use for severe painful tongue ulcer. The toxic symptoms developed when the amount of oral viscous lidocaine exceeded 240 ml per day. The serum lidocaine concentration associated with this use was 6.7 microg/ml. The toxic symptoms continued in spite of the serum lidocaine concentration below the toxic level after the start of a diluted preparation, which contained a half-dose lidocaine. It is speculated that lidocaine metabolites might have contributed to the toxic symptoms. Clinicians should consider the risk of lidocaine toxicity in cases of frequent viscous lidocaine use, and determine the serum concentrations of lidocaine and its metabolites.- - - - - - - - - - ranking = 1keywords = tongue (Clic here for more details about this article) |
2/35. tongue gastric choristoma: failure to localize by technetium-99m pertechnetate scan.Congenital rests of gastric epithelium have been reported in a variety of head and neck locations. Presenting symptoms of these lesions range from an asymptomatic cyst to one which is compromising the airway. The true diagnosis is rarely suspected prior to excision. A case of a gastric choristoma of the tongue is presented which was noted at birth as an intermittently bleeding ulcer. Complete excision of the mass was difficult to ascertain due to poor delineation of the tumor margins from the tongue musculature. A postoperative technetium-99m pertechnetate scan failed to demonstrate residual gastric mucosa. Conservative management resulted in only transient healing of the ulcer. Repeat excision demonstrated abundant residual gastric mucosa. technetium-99m pertechnetate scanning may not be a reliable indicator of ectopic gastric mucosa in the head and neck region.- - - - - - - - - - ranking = 0.4keywords = tongue (Clic here for more details about this article) |
3/35. Obstructive sleep apnoea syndrome presenting as lingual ulceration.Two patients with obstructive sleep apnoea syndrome are reported where the initial presenting complaint was of lingual ulceration. This unusual presentation has not been reported previously. Both patients experienced frequent apnoeic episodes during sleep with a profound fall in the arterial oxygen saturation. It is postulated that the lingual ulceration resulted from repeated trauma to the tongue by the teeth as the patient made violent inspiratory efforts at the termination of an apnoeic episode. The diagnosis of sleep apnoea syndrome was based upon suggestive symptoms of snoring, morning fatigue and day-time somnolence plus a minimum of 15 apnoeic episodes per hour of sleep. The first-line investigations of this condition are available in all district general hospitals and a diagnosis of sleep apnoea syndrome obtained. Referral to a regional sleep study centre may be appropriate prior to the commencement of therapy. Management is predominantly medical, consisting of weight loss and the administration of nocturnal nasal continuous positive airways pressure.- - - - - - - - - - ranking = 0.2keywords = tongue (Clic here for more details about this article) |
4/35. Oral histoplasma capsulatum infection in association with hiv infection: a case report.The fungus histoplasma capsulatum causes histoplasmosis, the most common endemic respiratory mycosis in the united states. Disseminated histoplasmosis in adults is often associated with immunosuppression, such as occurs in hiv infection. We report a case of oral histoplasmosis in an hiv-seropositive patient who presented with an ulceration on the left tip of the tongue, extending to the floor of the mouth, but was otherwise free of any active systemic disease. histoplasma capsulatum was shown, by both histopathology and staining with a fluorescent antibody reagent specific for the organism, to be present in the lesion and was deduced to be the causative organism.- - - - - - - - - - ranking = 0.2keywords = tongue (Clic here for more details about this article) |
5/35. Natural killer T-cell lymphoma of the tongue.lymphoma, which represents about 5.4% of all neoplasms and, more significantly, 19% to 28% of malignant neoplasms, is the most common nonepithelial malignancy of the head and neck area in Koreans. Natural killer T-cell (NK/T-cell) lymphoma is a lymphoma of putative natural killer cell lineage. NK/T-cell neoplasms are generally rare, but they are more common in people of East Asian, Mexican, or South American descent. These neoplasms are highly aggressive and show a strong association with Epstein-Barr virus. The preferential site of extranodal NK/T-cell lymphoma is the nasal cavity, and there has been no report of NK/T-cell lymphoma developing from the tongue. We encountered a rare case of NK/T-cell lymphoma of the tongue, which we report with a review of the literature.- - - - - - - - - - ranking = 1.2keywords = tongue (Clic here for more details about this article) |

7/35. Molecular detection of Cellulosimicrobium cellulans as the etiological agent of a chronic tongue ulcer in a human immunodeficiency virus-positive patient.Ulcerations appeared on the tongue of a 48-year-old human immunodeficiency virus-positive man. Histological findings of the biopsy specimen and the fact that the patient had resided in louisiana led us to suspect "American histoplasmosis". A new ulcer appeared while the patient was being treated with itraconazole, and the gene for 16S rRNA of Cellulosimicrobium cellulans was amplified. The lesions healed during treatment with oral penicillin and azithromycin.- - - - - - - - - - ranking = 1keywords = tongue (Clic here for more details about this article) |
8/35. Gingival lesions in lipoid proteinosis.Lipoid proteinosis is a rare heritable disease of the skin and mucous membranes characterized by subepithelial deposits of hyaline material. The morbid factors include disfiguring papulo-nodular lesions particularly of exposed skin, hoarseness of voice due to vocal cord infiltration, nodular deformation of the eyelids, and board-like rigidity of the tongue. Infiltration of the gingiva is usually unreported, and when mentioned has been equivocally related to the overall disease process. This patient demonstrates striking ulceration and hypertrophy with histologic evidence of heavy deposition of amorphous material confirming a gingival component to the lipoid proteinosis entity.- - - - - - - - - - ranking = 0.2keywords = tongue (Clic here for more details about this article) |
9/35. Arteriovenous malformation of the tongue.polyvinyl alcohol particles used to embolize an arteriovenous malformation of the tongue were only temporarily successful. Additional embolization therapy was necessary and was complicated by ischemic ulcers of the tongue. We conclude that embolization therapy can be used, but the efficacy of this therapy in the longer term remains to be determined.- - - - - - - - - - ranking = 1.2keywords = tongue (Clic here for more details about this article) |
