Abstract：
Lymphomas are a diverse group of neoplastic disorders arising primarily in lymph nodes. They have been majorly classified into Hodgkin and Non-Hodgkin lymphomas(NHL). NHL can be of B, T and Null cell categories having further subtypes based on their histological characteristics. Lymphomas can be nodal and extra nodal. The head and neck area are the second most common site of extra nodal lymphoma, with tonsils being the most common site of involvement; other sites include the nasopharynx and tongue base. B- Cell type being the most common type. Predominantly occurs in elderly. Presentations depends on the site involved. Various modalities like surgical treatment, chemotherapy (or) radiotherapy is available. Each stage has varied survival rates and prognosis and responses to the treat depending on the patient factors. In this paper, we report two cases of patients with non-Hodgkin lymphoma of tonsil, where the preoperative clinical diagnosis and radiological diagnosis was inconclusive and final diagnosis was established based on histopathological examination.
摘要：
淋巴瘤是一类主要在淋巴结中出现的肿瘤疾病。它们主要分为霍奇金淋巴瘤和非霍奇金淋巴瘤（NHL）。NHL可以是B，T和空细胞类别具有基于其组织学特征的其他亚型。淋巴瘤可以是淋巴结和淋巴结外。头颈部区域是结外淋巴瘤的第二常见部位，扁桃体是最常见的受累部位；其他部位包括鼻咽和舌根。B-细胞类型是最常见的类型。主要发生在老年人身上。演示文稿取决于所涉及的网站。各种方式，如手术治疗，化疗（或）放疗是可用的。取决于患者因素,每个阶段具有不同的存活率和预后以及对治疗的反应。在本文中,我们报告了2例扁桃体非霍奇金淋巴瘤患者，术前临床诊断和放射学诊断尚无定论，最终诊断是根据组织病理学检查确定的。
