Abstract:
Purpose To investigate the clinicopathological and immunohistochemical features of primary renal lymphomas ( PRL) , and to discuss the diagnosis, differential diagnosis, treatment and prognosis of the tumors. Methods Clinical data of 19 patients with PRL from January 2005 to October 2014 were retrospectively analyzed. Result The 19 patients in this study, there were 11 males and 8 females and the age ranged from 37 to 85 years old (averaged 55). Patients were mainly presented with unilateral renal masses, with lumbodynia as the main symptom. 13 patients underwent nephrectomy, 6 patients underwent renal biopsy and 17 patients received CHOP or R-CHOP chemotherapy. All of them were diagnosed as non-Hodgkin’ s lymphoma, with 14 cases of diffuse large B cell lym-phoma (DLBCL) (73. 684%, 14/19), 4 cases of B cell small cell lymphoma (21. 053%, 4/19), and 1 cases of T cell lymphoma (5. 263%, 1/19). Follow-up information was available in 15 patients. 12 were still alive and survived for 1~78 months, while the other 3 were dead with 1 case who died of cerebral infarction, and survived for 3~38 months ( averaged 23 months) . Conclusion PRL is an extranodal lymphoma which is rare in kidney and is often misdiagnosed as renal carcinomas due to its nonspecific clinical manifestations. The diagnosis of PRL can be confirmed by histopathological examination, immunohistochemistry and molecular analy-sis. The majority of the lymphomas are B cell lymphomas and most of them are DLBCL. The recommended treatment is surgery com-bined with chemotherapy and the prognosis is associated with the age, clinicopathological characteristics, tumor types and treatment.
