Primary non-Hodgkins lymphoma of the parotid gland.

UNLABELLED: Primary malignant lymphomas in the salivary glands are relatively rare. Clinical presentation is not characteristic and the disease is often overlooked resulting in diagnosis and treatment delays. AIM: To stress the importance of the diagnostic process and combined management, we present a series of eight patients with malignant lymphoma of the parotid who were diagnosed only after surgery and managed with radiation and chemotherapy. METHODS: Retrospective series of patients with primary malignant lymphoma of the parotid gland managed with radiotherapy and diagnostic surgical partial resection. RESULTS: After treatment completion we achieved a loco-regional control rate of 87.5%. Toxicity was charted according to the Common Toxicity Criteria and it was seen in six patients (75%). Six patients are still alive without evidence of recurrent disease in their last follow-up. CONCLUSION: Our study confirms that primary early stage Non-Hodgkin Lymphoma of the parotid gland is a disease with an excellent prognosis and a good local control rate, with minimal morbidity.

Linfomas primários das glândulas salivares são relativamente raros. Sua apresentação clínica não écaracterística e, frequentemente, a doença passa despercebida, resultando em atrasos no diagnóstico e tratamento. OBJETIVO: Enfatizar a importância do diagnóstico e tratamento combinado. Apresentamos uma casuística de oito pacientes com linfoma maligno da parótida, que foram diagnosticados somente após a cirurgia e tratados com radio e quimioterapia. MÉTODOS: Estudo retrospectivo de pacientes com linfoma maligno primário da glândula parótida, tratados com radioterapia e ressecção cirúrgica parcial diagnóstica. RESULTADOS: Após a conclusão do tratamento, atingimos uma taxa de controle loco-regional de 87,5 por cento. A toxicidade foi classificada de acordo com os Critérios Comuns de Toxicidade e afetou seis pacientes (75 por cento). Seis pacientes ainda estão vivos, sem evidência de doença na mais recente consulta de acompanhamento. CONCLUSÃO: Nosso estudo confirma que o Linfoma primário Não-Hodgkin em estágios iniciais da glândula parótida é uma doença com excelente prognóstico e boa taxa de controle local, com mínima morbidade.
