Abstract
ABSTRACT
Background and Objectives: Tonsils are lymphoid tissues that can be affected in various diseases. In some cases, it is necessary to remove tonsils through surgery. Although the diseases are often diagnosed by history-taking and physical examination that proceeds with surgery, histologic examination is necessary for confirmed diagnosis of malignancy. Considering the low prevalence of tonsil cancer, this study was performed to clinically examine tonsils for malignancies and evaluate the necessity of histopathological examination.
Methods: This retrospective study was conducted on 2,232 patients (aged 2-80 years) who had undergone tonsillectomy for various reasons in the city of Gorgan from 2001 to 2012. Medical history was obtained and physical examination was carried out before surgery. All the obtained samples were sent to the laboratory for histopathological examination. Finally, the collected data was analyzed.
Results: Only one case of lymphoma was found among the 2,232 patients investigated in this study. This 80-year-old woman with preoperative cervical lymphadenopathy and unilateral tonsillar enlargement went under tonsillectomy for confirmed diagnosis.
Conclusion: Considering the high frequency of tonsillectomy and the low possibility of malignancy, and the fact that malignancy is often seen in individuals with obvious clinical presentations such as in our case, it is recommended to limit referral of specimens for histological examination to highly suspicious cases through more rational decision-making and summarization of other findings.

Abstract
Background: Non-Hodgkin lymphoma (NHL) represents a heterogeneous group of lymphoproliferative malignancies with unique presentation and treatment response. This study was intended to assess the histomorphology of non-Hodgkin lymphoma subtypes and correlate with clinicopathological and immunohistochemical findings.
Methods: This retrospective study was conducted on all specimens diagnosed as NHL by histopathological analysis, with immunohistochemical correlation in the pathology department, for two years. Clinical details such as age, gender, site of the lesion, and Nodal / extranodal presentation were recorded. Histopathological analysis was performed, and Immunohistochemical (IHC) reports were obtained. Further histopathological findings were correlated with IHC results. Statistical analysis was done based on the frequency distribution.
Results: This study includes 48 cases. Most cases are 61 to 70 years old, with a male predominance (56.25 %). The most common clinical diagnosis was lymphoma (79.17 %). Most of the lesions were of lymph nodal origin (60.42 %). The cervical group (35.42 %) is the most common lymph node affected, followed by the axillary nodes. The most common extranodal sites are the retroperitoneum and stomach. On histopathological evaluation, the most common diagnosis was NHL (68.75 %) without further subtyping. Among cases where subtyping was done, the most common lesion were follicular lymphoma and diffuse large B-cell lymphoma (DLBCL). On IHC evaluation, B cell neoplasms (85.42%) were common compared to T cell neoplasms (14.58 %). The most common subtype was DLBCL (52.08 %), followed by follicular lymphoma (16.67 %).
Conclusion: Our study found diffuse large B cell lymphoma (DLBCL) as the most common type of Non-Hodgkin’s Lymphoma. Cervical lymph nodes were found to be the most common site of involvement. But the involvement of rare sites like the testis and palate was also found. Hence the probability of NHL in these rare sites should always be considered.
