Resumo Um cisto odontogénico calcificante pode estar associado a tumores odontogénicos, particularmente odontomas. No entanto, a associação entre cisto odontogénico calcificante e cistos odontogénicos é rara. O objetivo deste estudo é relatar o primeiro caso de um cisto odontogénico calcificante associado a um pseudocisto antral. Um paciente do sexo masculino apresentou lesão tumoral em rebordo alveolar superior direito após 6 meses de evolução e quadro doloroso. A radiografia panorâmica indicou lesão radiolúcida entre os dentes 13 a 15 e velamento do seio maxilar. Foi realizada biópsia excisional e realizado diagnóstico histopatológico de cisto odontogénico calcificante associado a pseudocisto antral. O tratamento de escolha foi a enucleação das lesões e curetagem. A paciente está em acompanhamento há cerca de 3 anos sem recidiva da lesão, caracterizando comportamento indolente do cisto odontogénico calcificante.

Abstract A calcifying odontogenic cyst may be associated with odontogenic tumors, particularly odontomas. However, the association between calcifying odontogenic cysts and odontogenic cysts is rare. This study aims to report the first case of a calcifying odontogenic cyst associated with an antral pseudocyst. A male patient presented a tumor lesion in his right maxillary alveolar ridge with 6 months of evolution and painful symptoms . An excisional biopsy was performed, and a histopathological diagnosis of calcifying odontogenic cyst associated with an antral pseudocyst was issued. The treatment of choice was lesion enucleation and curettage. The patient has been under follow-up for about 3 years without lesion recurrence, which is typical indolent calcifying odontogenic cyst behavior.

ABSTRACT: The aim of this work was to trace an epidemiological and clinical profile of oral squamous cell carcinoma (SCC) cases diagnosed as lip and tongue SCC from June 2001 to 2018 at a pathology anatomy service located in Northeastern Brazil. Age, sex, duration, location, growth type, staining, metastasis, etiologic agents and lesion size data were obtained fr om patient clinical files and histopathological reports. A total of 124 cases were recorded, with tongue SCC being the most preval ent. The common characteristics of both assessed SCCs included higher frequency in men, mean age of 60 years old, evidence mostly of exophytic lesions and maximum size of 4 cm, predominantly diagnosed after a maximum of 1 year of appearance. Regarding divergent findings, lip SCC occurred mostly in the lower portion of the lip, presenting a predominantly leukoplastic color, with regular smoking habits and sunlight identified as the main etiological agents, and no strong relation to metastasis. On the other hand, tongue SCC mostly exhibiting predominantly erythroleukoplastic staining, with a greater relationship to alcohol - associated smoking and regular smoking habits. The highest percentage of patients with metastasis presented tongue SCC. Although lip and tongue SCC display a male preference, an increasing amount of female involvement has been noted over the years, due to the adoption of deleterious habits such as smoking and alcoholism. Tongue SCC presented a greater relationship with metastasis and clinical leukoeritroplastic evidence. This greater aggressiveness could be related to the unfavorable locat ion of these lesions in relation to lip SCC, sometimes making it difficult to identify in their early development stages.

RESUMEN: El objetivo de este trabajo fue rastrear un perfil epidemiológico y clínico de los casos de carcinoma oral de células escamosas (CCE) diagnosticados como CCE de labios y lengua entre junio de 2001 y 2018 en un servicio de anatomía patológica ubicado en el Noreste de Brasil. Los datos de edad, sexo, duración, ubicación, tipo de crecimiento, tinción, metástasis, agentes etiológicos y tamaño de la lesión se obtuvieron de los archivos clínicos de los pacientes y los informes histopatológicos. Se revisaron un total de 124 casos, siendo el CCE de lengua el más prevalente. Las características comunes de ambos CCE evaluados incluyeron mayor frecuencia en hombres, edad promedio de 60 años, evidencia mayoritariamente de lesiones exofíticas y tamaño máximo de 4 cm, diagnosticado predominantemente después de un máximo de 1 año de aparición. En cuanto a los hallazgos divergentes, el CCE labial se presentó mayoritariamente en la porción inferior del labio, presentando un color predominantemente leucoplásico, con el hábito de fumar habitualmente y la luz solar identificados como los principales agentes etiológicos, sin una fuerte relación con las metástasis. Por otro lado, el CEC de la lengua presenta en su mayoría tinción predominantemente eritroleucoplásica, con una mayor relación con el tabaquismo asociado con el alcohol y con los hábitos habituales de tabaquismo. El mayor porcentaje de pacientes con metástasis presentó CCE de lengua. Aunque el CCE de labios y lengua muestra una preferencia en hombres, se ha observado una cantidad cada vez mayor prevalencia en mujeres a lo largo de los años, debido a la adopción de hábitos nocivos como el tabaquismo y el alcoholismo. El CCE de lengua presentó una mayor relación con la metástasis y la evidencia clínica leucoeritroplásica. Esta mayor agresividad podría estar relacionada con la ubicación desfavorable de estas lesiones en relación al CCE labial, dificultando en ocasiones su identificación en sus primeras etapas de desarrollo.

PURPOSE: To conduct a systematized review of the literature about the main local hemostatic measures to control postoperative bleeding in anticoagulated patients. METHODS: A systematized review of literature was performed in the electronic database Medline (PubMed) without restriction of the publication date. The eligibility criteria were studies involving maintenance of the anticoagulant therapy, prospective studies, retrospective studies, randomized clinical trials, controlled clinical studies, comparative studies, multicentric studies or case-control studies. Studies discontinuing anticoagulant therapy, case reports, literature reviews, in vitro studies, animal experiments and articles written in language not compatible with the search strategy adopted in this work were excluded. RESULTS: Twenty-four articles that met the adopted eligibility criteria were selected, enrolling 3891 subjects under anticoagulant therapy. A total of 171 cases of hemorrhage was observed. Tranexamic acid was the main local hemostatic measure used to controlling of postoperative bleeding. CONCLUSION: The local hemostatic measures proved to be effective according to previously published studies. Nevertheless, further clinical studies should be conducted to confirm this effectiveness.
