Occurrence of dermoid cyst in the floor of the mouth: the importance of differential diagnosis in pediatric patients

Abstract Lesions in the floor of the mouth can be a challenging diagnosis due to the variety of pathological conditions that might be found in this area. Within a broad range of lesions, attention has to be addressed to those that require specific management, such as a dermoid cyst (DC) and a ranula. Especially in pediatric patients, in whom the failure of diagnosis can postpone the correct treatment and cause sequelae later in life. DC, a developmental anomaly, is managed primarily by surgical resection. On the other hand, ranula is a pseudocyst that may be treated by marsupialization. This article reports a large and painful lesion in the floor of the mouth in a pediatric patient. With a diagnostic hypothesis of ranula, two surgical interventions were performed, but there were recurrences of the lesion. Subsequently, the patient was referred to the Oral and Maxillofacial Surgery Unit for re-evaluation. Computed tomography showed a semi-transparent image suggesting a cystic formation. Another surgical procedure was performed where the lesion was completely removed. Anatomopathological analysis confirmed the diagnosis of DC. The five-year follow-up showed no signs of recurrence. This article indicates that although DC in the floor of the mouth is rare, it should be considered in the differential diagnosis of other diseases in this area. This precaution may be particularly important in the following circumstances: 1) Similar lesions that have different therapeutic approaches and, 2) To prevent future sequelae in pediatric patients.

Impact of burning mouth syndrome on quality of life / Impacto da síndrome da ardência bucal na qualidade de vida

OBJECTIVE: To determine the impact of Burning mouth syndrome (BMS) on the quality of life of patients by means of the World Health Organization Abbreviated Instrument for Quality of Life Assessment (WHOQOL-26). METHODS: A total of 116 patients were selected, 58 with BMS and 58 controls. Individuals with changes in the hemogram and in the blood levels of glucose, iron, folic acid and vitamin B12 were excluded, as well as those who used antidepressant and/or anxiolytic drugs or who showed a salivary flow rate of less than 0.1 mL/min. RESULTS: The overall score of the WHOQOL-26 was significantly lower in the group with the disorder (P<0.001). The patients with BMS also displayed significantly lower scores when compared to controls in relation to the psychological and physical domains of the instrument (P=0.005 and P<0.001, respectively). There was no significant difference between BMS and control patients with respect to scores of the social and environment domains. CONCLUSIONS: BMS interferes with the quality of life of patients in a negative way, and therefore, its management is a challenge for the clinicians, who should treat the individual with this disorder in a broader context.

OBJETIVO: Avaliar o impacto da Síndrome da Ardência Bucal (SAB) na qualidade de vida dos pacientes por meio do Instrumento Abreviado de Avaliação de Qualidade de Vida da Organização Mundial de Saúde (WHOQOL-26). MÉTODOS: Foram selecionados 116 pacientes de ambos os sexos, com idade mínima de 40 anos, 58 portadores de SAB e 58 indivíduos-controle. Indivíduos com alterações no hemograma, nas concentrações de glicose, ferro, ácido fólico e vitamina B12 foram excluídos, bem como aqueles que utilizassem fármacos antidepressivos, ansiolíticos ou que apresentassem velocidade de fluxo salivar inferior a 0,1 mL/min. RESULTADOS: O escore geral do WHOQOL-26 foi significativamente inferior no grupo com a doença (P<0,001). Os pacientes com SAB também apresentaram escores significativamente inferiores em relação aos domínios psicológico e físico do instrumento (P=0,005 e P<0,001, respectivamente). Não houve diferença significativa entre os grupos quanto aos escores dos domínios social e ambiental do questionário. CONCLUSÃO: A SAB interfere de forma negativa na qualidade de vida dos pacientes, por isso, é importante que o cirurgião-dentista avalie o paciente com a doença dentro de um contexto mais amplo.
