Objective:
To evaluate the clinical-pathological profile of patients with minor salivary gland neoplasms.
Methods:
A retrospective study of specific cases diagnosed as benign and malignant tumors of the minor salivary glands was performed. The data were collected from medical records of patients seen at a hospital over a period of 15 years. The sample was made up of 37 cases. For the pathological study, slides containing 5μm thick sections stained with hematoxylin and eosin were used. The data were tabulated using descriptive statistics.
Results:
Malignant neoplasms represented 70.3% of cases. The mucoepidermoid carcinoma was the most common neoplasm (45.9%), followed by pleomorphic adenoma (24.4%). Most patients were female (70.3%), aged between 71 and 80 years. The palate (67.6%) and the retromolar region (10.8%) were the most affected sites.
Conclusion:
Mucoepidermoid carcinoma was the most common tumor in minor salivary glands. These tumors are more common in females aged over 40 years. The palate was the most common affected site.
Objetivo:
Avaliar o perfil clínico-patológico de pacientes com neoplasias de glândula salivar menor.
MéTodos:
Foi realizado um estudo retrospectivo de casos específicos diagnosticados como neoplasias benignas ou malignas de glândula salivar menor. Os dados foram coletados dos prontuários dos pacientes atendidos em um hospital no período de 15 anos. A amostra final foi de 37 casos. Para o estudo histopatológico, foram usadas lâminas contendo secções com 5μm de espessura, coradas pela técnica de hematoxilina e eosina. Os dados foram tabulados de forma descritiva.
Resultados:
As neoplasias malignas representaram 70,3% dos casos. O tipo histológico mais prevalente foi o carcinoma mucoepidermoide (45,9%), seguido do adenoma pleomórfico (24,4%). A maioria dos pacientes era do sexo feminino (70,3%), com idade entre 71 e 80 anos. O palato (67,6%) e a região retromolar (10,8%) foram os sítios mais acometidos.
ConclusãO:
O carcinoma mucoepidermoide foi o tumor mais comum das glândulas salivares menores. Estes tumores foram mais comuns em mulheres com mais de 40 anos. O palato foi o sítio mais acometido.
