[Lingual necrosis as a form of presentation of temporary arteritis]. / Necrosis lingual como forma de presentación de arteritis temporal.

Giant cell arteritis is a systemic vasculitis that affects arteries of medium and large caliber, mainly the aorta artery and its main branches. It is more frequent in women older than 50 years. The most common symptoms are fever, jaw claudication, headache, hyperesthesia of the scalp and loss of vision with anterior ischemic optic nerve disease. But, in a minority of cases, less frequent symptoms are observed that delay and make more difficult the diagnosis. Here, we present the case of a 76-year-old woman who came to our consultation having pain in the oral cavity and presenting tongue and neck edema for 48 hours. She had also suffered from headaches during the previous month. Because the physical examination showed clinical signs of lingual ischemia, a presumptive diagnosis of ischemic involvement due to giant cell arteritis was considered. She started a treatment with systemic corticosteroids and a temporal artery biopsy was performed. We conclude, that giant cell arteritis should be suspected in patients presenting lingual ischemia symptoms in order to start the specific treatment early enough to avoid irreversible complications.

La arteritis de células gigantes es una vasculitis sistémica que compromete arterias de mediano y gran calibre, principalmente la arteria aorta y sus ramas. Su prevalencia es mayor en mujeres a partir de los 50 años, típicamente se manifiesta con fiebre, claudicación mandibular, cefalea, hiperestesia del cuero cabelludo y pérdida de la visión con neuropatía óptica isquémica anterior, en una minoría de casos aparecen síntomas menos frecuentes que dificultan y retrasan el diagnóstico. Se presenta el caso de una mujer de 76 años que consultó por dolor en la cavidad bucal con edema lingual y en cuello de 48 horas de evolución asociado a cefalea el mes previo. En el examen físico presentaba signos clínicos de isquemia lingual, por lo que se consideró como diagnóstico presuntivo compromiso isquémico por arteritis de células gigantes, e inició tratamiento con corticoides sistémicos realizándose una biopsia de arteria temporal que evidenció infiltrado linfocitario panparietal con engrosamiento de la túnica íntima y hallazgos compatibles con panarteritis. La arteritis de células gigantes debe ser sospechada en pacientes con manifestaciones de isquemia lingual, iniciándose en forma precoz el tratamiento para evitar complicaciones irreversibles.

Copaiba oil-resin (Copaifera reticulata Ducke) modulates the inflammation in a model of injury to rats' tongues.

BACKGROUND: The regeneration of integrity and tissue homeostasis after injury is a fundamental property and involves complex biological processes fully dynamic and interconnected. Although there are medications prescribed to accelerate the process of wound healing by reducing the exaggerated inflammatory response, comes the need to search for different compounds of Amazonian biodiversity that can contribute to the acceleration of the healing process. Among these products, the copaiba oil-resin is one of the most prominent feature in this scenario, as they have been reported its medicinal properties. METHODS: Aiming to evaluate the anti-inflammatory and healing effect of copaiba oil-resin (Copaifera reticulata Ducke) in transfixing injury of rats' tongues first proceeded up the copaiba oil-resin oral toxicity test in 5 male mice to stipulate the therapeutic dose which was established at 200 mg/kg/day. Then it was induced transfixing injury in a total of 15 Wistar rats. The animals were randomly divided into three groups based on the treatment: control group, dexamethasone group and copaiba oil-resin group. After 7 days of treatment, histological slides stained with hematoxylin and eosin was prepared. Immunohistochemistry for CD68 (macrophage marker) was performed and analyzed by the cell counter Image J. RESULTS: The acute toxicity test showed that the oil-resin copal has low toxicity. Furthermore, copaiba oil-resin therapy modulates the inflammatory response by decreasing the chronic inflammatory infiltrate, edema and specifically the number of macrophages. CONCLUSIONS: The results indicate the potential of the Amazon region and showed up relevant because therapy with this extract modulates the inflammatory process.

Topical application of Aloe vera and vitamin E on induced ulcers on the tongue of rats subjected to radiation: clinical and histological evaluation.

OBJECTIVE: The aim of this study is to assess the effect of two types of antioxidants, vitamin E (VE) and Aloe vera (AV), on healing of induced oral lesions after radiation in a murine model by clinical and histological analysis. METHODS: The animals were randomly divided into three groups of 12 animals each (400 mg VE, 70 % AV and control) and two time periods (5 and 7 days). They were irradiated with a single dose of 30 Gy, and after 24 h, a lesion was produced on the ventral tongue of each animal. The products were applied daily in their respective group until euthanasia. RESULTS: On clinical analysis, there was a higher frequency of lesions in the animals of the control group at both periods. The area of the lesions was also greater in the control group compared with the groups AV and VE (5 days p = 0.006; 7 days p = 0.002). On microscopic analysis, the degree of inflammation differed between the study groups and experimental periods. At 5 days, the statistical difference was not significant among the groups evaluated, but at 7 days, animals in the control group showed intense inflammation, while those in groups VE and AV exhibited mild to moderate inflammation (p = 0.002). CONCLUSION: The results suggest that VE and AV contributed to the decrease in inflammatory response and healing of the lesions induced on the tongue of rats subjected to radiation.

Paracoccidioidomycosis mimicking squamous cell carcinoma on the dorsum of the tongue and review of published literature.

INTRODUCTION: Paracoccidioidomycosis is a disease that is endemic to southern and southeastern Brazil, caused by the fungus Paracoccidioides brasiliensis. The most common clinical oral manifestation is the presence of multiple granulomatous ulcers with hemorrhagic dots, located mainly on the lips, palate, and buccal mucosa. However, the disease can manifest atypically as a single ulcer, mimicking oral squamous cell carcinoma (SCC) or tuberculosis. CASE REPORT: A 65-year-old male patient presented with a complaint of a single ulcerated lesion on the dorsum of the tongue; the lesion had evolved over 6 months. The diagnostic hypotheses were SCC and oral manifestation of tuberculosis. An incisional biopsy was performed, and histopathological analysis of the specimen revealed pseudoepitheliomatous hyperplasia, a granulomatous structure of epithelioid histiocytes, multinucleated giant cells, and lymphocytes in the connective tissue. Grocott staining confirmed the presence of the fungus in the lesion, and a diagnosis was made of paracoccidioidomycosis. The patient was treated with 200 mg/day of itraconazole for 12 months and now shows no signs or symptoms of recurrence of the disease. CONCLUSION: Correct diagnosis is essential for a successful therapeutic approach and resolution of the lesion.

Conventional systemic treatments associated with therapeutic sites of local lesions of secondary syphilis in the oral cavity in patients with AIDS.

Patients with HIV infection may develop common diseases with atypical clinical features. HIV infection can change the classic clinical course of syphilis and increase the incidence of malignant syphilis. Malignant syphilis is a rare subtype of secondary syphilis that presents special clinical and histological features and has been associated with several processes characterized by variable degrees of immunosuppression. It is necessary to consider the possibility of this entity in the differential diagnoses in HIV-infected patients with cutaneous lesions. The dental surgeon (or oral surgeon) is vital to the medical team for promoting the health and improving the quality of life of syphilis patients. A patient with HIV infection was referred to us for complaints of a white patch on the tongue, stinging and burning sensation on the tongue, loss of taste, and dryness of the mouth. On clinical examination, the patient was found to have a tabetic gait (the Prussian soldier gait) associated with Charcot arthropathy. We also identified bilateral lesions with ulceration and exposure of the tissue that were tender, characterized by discrete necrosis. The treatment that was initiated at that time involved cleaning the area with gauze to remove all the white patches, followed by rinsing with bicarbonate in water (one teaspoon of baking soda dissolved in half a glass of water) four times a day. Additionally, fluconazole (100 mg/day for 7 days) was prescribed. We diagnosed secondary malignant syphilis of approximately 5 days duration. As an adjunctive therapy, we performed low-intensity laser treatment using a GaAsAl (gallium-aluminum arsenide) laser at 790 nm. With this treatment there was progressive resolution of the lesions.

Lichen sclerosus of the oral mucosa: clinicopathological features of six cases.

Lichen sclerosus is a chronic inflammatory mucocutaneous disease, rarely involving the mouth. There are only 20 well-documented cases of oral lichen sclerosus reported in the English-language literature. This report describes the clinicopathological features of 6 cases of oral lichen sclerosus; 5 in women. There were 12 lesions, mainly on the lips (50%) and buccal mucosa (25%). The affected areas appeared as irregular whitish patches, harder than the surrounding tissue. Half of the patients were symptomatic and presented with no associated skin and/or genital lesions. All cases were biopsied, and histopathological features were evaluated using hematoxylin-eosin and Verhoeff's stains, S-100 immunohistochemical reaction and transmission electron microscopy. Management of the oral lesions consisted of surgical excision, intralesional triamcinolone acetonide, oral colchicine, and regular follow-up. There is no effective curative treatment, but there are some options for patient management; and colchicine may be considered an additional choice.

Evaluation of a new mouthwash on caseous formation.

UNLABELLED: Tonsil caseous affects a significant percentage of the population. Surgeries, conservative or not, have been the only viable alternatives of treatment. However, today there is still not, up to now, an economical and non-invasive treatment that presents satisfactory results. AIMS: The objectives of this study are to evaluate the efficiency of a mouthwash, with active ingredients that associate oxygenating and antimicrobial substances, in the reduction of caseous and tongue coating formation, whose etiology is similar to caseous, and to evaluate the reduction of the volatile sulfur compounds (VSCs) concentration. STUDY DESIGN: Double blind, placebo-controlled, randomized, clinical and experimental study. MATERIAL AND METHODS: [corrected] A sample of 50 volunteers with more than one year of chronic caseous tonsillitis complaint used it. The research was carried out in 2005, in the cities of São Paulo and Campinas. RESULTS: For the group that used the placebo solution, there was no correlation between the variables or statistical significance in the results. For the group that used the mouthwash, the results were significant in all analyzed questions. CONCLUSIONS: This new mouthwash proved to be a viable conservative alternative for the treatment of tonsil caseous, being also efficient in the reduction of tongue coating formation and VSCs concentration.

Avaliação de um novo enxaguatório na formação de cáseos amigdalianos / Evaluation of a new mouthwash on caseous formation

Os cáseos amigdalianos afetam uma significativa porcentagem da população. As cirurgias, conservadoras ou não, têm sido as únicas alternativas viáveis de tratamento. Entretanto, ainda hoje não há um método econômico e não-invasivo de tratamento que apresente resultados satisfatórios. OBJETIVOS: Os objetivos deste estudo são avaliar a eficiência de um enxaguatório, cujos ingredientes ativos associam substâncias oxigenantes e antimicrobianas, na diminuição da formação dos cáseos amigdalianos e da saburra lingual, cuja etiologia é semelhante à dos cáseos, e avaliar a redução da concentração dos compostos sulfurados voláteis (CSVs). FORMA DE ESTUDO: Estudo clínico e experimental, randomizado, duplo-cego, placebo-controlado. MATERIAL E MÉTODO: Foi utilizada uma amostra de 50 voluntários, com queixa de tonsilite crônica caseosa há mais de um ano. A pesquisa foi realizada em 2005, nas cidades de São Paulo e Campinas. RESULTADOS: Para o grupo que utilizou a solução placebo, não houve correlação entre as variáveis nem significância estatística nos resultados. Para o grupo que utilizou o enxaguatório, os resultados foram significativos em todos os quesitos analisados. CONCLUSÕES: O novo enxaguatório demonstrou ser uma alternativa conservadora viável para o tratamento da tonsilite crônica caseosa, sendo eficiente também na redução da formação de saburra lingual e concentração dos CSVs.

Primary aspergillosis affecting the tongue of a leukemic patient.

We describe a case of primary aspergillosis involving the tongue of a patient with acute myeloid leukemia. Intraoral aspergillosis is very rare and we found only 23 cases reported in the English literature. Clinically it was a 2-cm, ulcerated, grayish lesion on the dorsum of the tongue. Microscopically there was invasion of the epithelium, connective tissue and muscle of the tongue by fungal hyphae branching at 45 degrees angle. The large hyphae were easily seen by H & E stain, and were strongly positive for periodic acid-Schiff and Grocott methenamine. The patient was successfully treated with intravenous amphotericin B. Based on clinical, microscopic and culture data, the diagnosis of primary aspergillosis of the tongue was established. Invasive oral aspergillosis is a potentially lethal disease and it should be considered in immunosuppressed patients.

Cystic echinococcosis of the tongue leading to diagnosis of multiple localizations.

The tongue is a rare site of localization of cystic echinococcosis. We report a 3-year-old patient with cystic echinococcosis of the tongue demonstrated by histopathology. The cyst of the tongue was surgically removed. The tongue lesion led us to find additional liver and lung cystic lesions that were successfully treated with albendazole therapy.

[Sarcoidosis of the tongue. Apropos a case]. / Sarcoidosis de la lengua. A propósito de un caso.

Here we present the case of a patient with lesion on the tongue, during more than 6 months, which in its self required different therapeutic measures and because of a benign evolution is remitted to this center for study, which concluded with an histological diagnosis of sarcoidosis, a granulomatous disease systemic in character which in this patient only affect the tongue which reminds us daily the necessity to remember this entity by internist, gastroenterologists and dentists.

[Tuberculous ulcer of the tongue: clinical case]. / Ulcera tuberculosa de la lengua: caso clinico.

A 26 year-old female was seeking treatment for a painless ulcerated lesion of the tongue developing 30 days before. No history of a sef biting in that area was told by the patient. Following a provisional diagnosis of tuberculous ulcer or a neoplasm, under local anesthesia, a segment of the lesion was excised and sent to histological diagnosis, which confirmed the existence of a tuberculous ulcer. Additionally, a chest roentgenogram disclosed the presence of an undiagnosed pulmonar tuberculous lesion. The patient underwent a successful treatment with rifampicin, isoniazide and pirazinamide, and two month after the initial diagnosis the oral lesion was almost absent, although the pulmonar lesion was still detected on the roentgenogram. Finally, a total disappearance of the pulmonar lesion was detected six month following drug treatment.
