Carcinoma gengival: um relatório de caso

Squamous-cell carcinoma is a malignant epithelial neoplasm characterized by various clinical manifestations. Present study aimed to report a case of gingival squamous-cell carcinoma in a who patient did not present risk factors associated with the referred neoplasm. A 95-year-old female, attended dental services exposing a rapidly growing, painful proliferative lesion of 6 months of evolution, located in vestibular marginal gingiva, which affected teeth # 33-32-31-43-42-41. According to clinical symptoms and differential diagnosis (central giant cell granuloma and malignant neoplasm), an excisional biopsy was obtained. Diagnosis of referred carcinoma was obtained after three days of patient decease consequent to a severe dyspnea case. Gingival squamous-cell carcinoma is a condition that usually has a good prognostic when diagnostic and treatment are established on time. This study reports a clinical case of a patient who died before having an opportunity to access treatment.El carcinoma de células escamosas o escamocelular es una neoplasia epitelial maligna que se caracteriza por que sus manifestaciones clínicas son variadas. El objetivo de este artículo es presentar el caso clínico de un paciente con carcinoma gingival de células escamosas, sin antecedentes de factores de riesgo comunes para el desarrollo de esta neoplasia. Mujer de 95 años con un historial de 6 meses de una lesión proliferativa dolorosa y de rápido crecimiento en la encía marginal vestibular de los dientes # 33-32-31-43-42-41. De acuerdo con los signos y síntomas clínicos, se da una impresión clínica de carcinoma gingival y un diagnóstico diferencial de granuloma central de células gigantes, se tomó una biopsia por escisión de la lesión. El diagnóstico fue de carcinoma de células escamosas. Después de tres días, la paciente falleció en el hospital por un cuadro de disnea severa que le produjo un paro cardiorrespiratorio. El carcinoma gingival de células escamosas es una afección con un buen pronóstico cuando se diagnostica y trata a tiempo, este articulo informó un caso de un paciente que falleció antes de realizar un tratamiento a lesión tumoral.O carcinoma de células escamosas é uma neoplasia epitelial maligna caracterizada por manifestações clínicas variáveis. O objetivo deste estudo foi relatar um caso de carcinoma espinocelular, no qual o paciente não apresentava fatores de risco para o desenvolvimento dessa neoplasia. Uma mulher de 95 anos de idade foi observada com 6 meses de história de uma lesão proliferativa dolorosa de crescimento rápido na gengiva marginal vestibular na zona dos dentes # 33-32-31-43-42-41. Assim, diante dos sintomas clínicos e do diagnóstico diferencial de granuloma central de células gigantes e neoplasia maligna, foi obtida uma biópsia excisional da lesão.Foi feito o diagnóstico de carcinoma espinocelular. Após três dias, o paciente falecido no hospital apresentou dispnéia grave. O carcinoma de células escamosas gengival é uma condição com bom prognóstico quando diagnosticado e tratado precocemente. Este estudo relatou um caso de paciente que morreu antes de realizar um tratamento tumoral

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
