ABSTRACT Background: We present a case of primary renal lymphoma no bilateral Hodgkin of both kidneys which is uncommon Objective: To present the clinical case of a patient that dies four days of their entrance in which was discovered a bilateral renal mass with the anatomopathological diagnostic of primary renal lymphoma for necropsy stud . Case presentation: It is a 40 year-old patient, with family antecedents of neoplasias and personal of gastritis of seven months of evolution. The patient was entered for fever of 39 ^oC an important abdominal pain, in which was important the anemic and constitutional syndrome with loss of 11 kg in the last months; and diminished diuresis. A tumor was verified between 12 and 15 cm in both flanks of hard and not painful irregular surface. The patient presented unfavorable evolution for what was moved to room of cares intermissions. In the analytic study they were verified as exams of importance the Hb 89 g/L, the speed of globular sedimentation of 95 mm/1era hra, the LDH 1495 UI/L, the creatinine of 537 mmol /L and several pathological glycemias one of them of 20 mmol/L. The x- ray results as much the ultrasonography as the contrasted on-line axial tomography guided the possibility to be a renal tumor. The medullogram and the laparoscopic were not useful for the diagnosis. The patient died and she was carried out histopathological necropsy study, which informed a lymphoma not bilateral Hodgkin of kidney of cells B, without an affectation to another organ Conclusions: They are uncommon the cases of primary renal lymphoma, since the renal affectation for a process lymphproliferative is in general secondary to a systemic illness. This case completes the fundamental approaches of Malbrain to consider it as a lymphoma non Hodgkin. The diagnosis is carried out by means of renal biopsy, during the surgery or necropsy for anatomopathological study.
