    Primary renal lymphoma (PRL) is rare, accounting for only 0.7% of extranodal primary malignant lymphomas [1]. There are more than 70 cases reported abroad, and only sporadic reports have been seen in China. Lymphoma is a malignant tumor that originates in lymph nodes or lymph tissues. It is divided into two categories: Hodgkin's disease and non-Hodgkin's lymphoma according to histopathological characteristics. Hodgkin’s disease often accumulates confined, concentrically distributed lymph nodes, and the lesion progresses along adjacent lymph nodes. Less than 10% of extra-lymph node lesions occur. Therefore, this type is rare in urinary and male reproductive system lymphomas. Non-Hodgkin’s lymphoma lesions range Extensive, extranodal lesions are more common. Extranodal lymphoma is mainly non-Hodgkin's lymphoma, with more than 90% secondary, and primary lymphoma is rare. Many scholars question whether there is distant primary lymphoma in the kidney, because ①the kidney itself does not have lymphatic tissue ②The kidney is the most common site of extranodal metastasis of intranodal lymphoma, which accounts for 30% of extranodal metastasis of lymphoma -50%[2]③The autopsy data of "primary renal lymphoma" showed that most patients had extrarenal lymphoma[3], but two scholars each had a case of primary large B-cell lymphoma of the kidney The follow-up results confirmed that there is indeed a primary lymphoma in the kidney [4].

    Primary renal lymphoma is diagnosed on the basis of ①There are diffuse and uniform lymphoma cell infiltration in the kidney ②The tumor is mainly located in the kidney, and tumor cell infiltration can also be seen in the renal capsule and surrounding adipose tissue ③The patient's body is superficial Lymph nodes and deep lymph nodes are not enlarged ④ without leukemic blood picture and bone marrow suppression [5]. Because imaging examinations are not specific, the final diagnosis can be made only by surgery and pathology. The prognosis of this disease is poor, with an average survival period of six months [6]. The more recognized treatment is nephrectomy plus chemotherapy and/or radiotherapy.
