Abstract: Objective: To study the clinicopathological characteristics of non-Hodgkin lymphoma（NHL） of the prostate. Methods: We collected the clinical data on 6 cases of NHL of the prostate pathologically confirmed between 2001 and 2017. The patients were aged 49-76（median 62） years old, with the main clinical manifestations of painless swelling of the prostate and lower urinary tract obstruction. We analyzed the clinical features and the results of histological detection, immunohistochemical staining and B-cell gene rearrangement assay, and explored the clinicopathological characteristics and differential diagnosis of the disease based on the relevant literature. Results: Histological detection revealed diffuse large B-cell lymphoma（DLBCL） in 4 cases（66.7%）, B-lymphoblastic lymphoma（B-LBL） in 1（16.7%）, and Burkitt lymphoma（BL） in another（16.7%）. DLBCL was histologically characterized by diffuse oval or round medium-to-large-sized lyphoid cells with an infiltrative growth pattern, B-LBL by monotonous small-to-medium-sized lymphoid cells with prominet mitosis and apoptosis, and BL by diffuse and monotonous medium-sized neoplastic cells with round or oval nuclei, an infiltrative growth pattern, scanty cytoplasm and visible mitosis. One of the DLBCL patients received 5 doses of R-CHOP chemotherapy and has been followed up to the present time, while the other 3 were lost to follow-up; the B-LBL patient died at 1 month after diagnosis; and the BL patient gave up treatment. Conclusion: Non-Hodgkin’s lymphoma of the prostate mostly presents as diffuse large B-cell lymphoma, and its diagnosis depends on immunohistochemistry and related molecular detection as well as its clinical and histopathological manifestations.
