Diagnosis of primary renal lymphoma is important for the patients to receive appropriate therapy.Laparoscopic nephrectomy should be the standard procedure in most cases of both malignant and benign,renal tumors with the possible exception of tumor】10cm.Probably this case report of laparoscopic surgery of primary renal lymphoma is the first report of this kind and may be useful for the other laparoscopic surgeons.A 53 years-old man with unilateral primary renal lymphoma who had a history of renal colic and ESWL(Extracorporeal Shock Wave Lithotripsy) of the left kidney stone 3 years ago,he underwent laparoscopic radical left nephrectomy and chemotherapy. The patient was monitored for follow up for 4 months and had a significant improvement.Although treatment of lymphoma is now guided by phenotype of tumor,we found that appropriate treatment is possible after radical nephrectomy and assessment of pathology.Renal lesions may compeletly regress by appropriate treatment.There was not any report of laparoscopic surgery of PRL in our literature.We are reporting the first case of successful laparoscopic surgery of PRL successfully.展开更多

Tumor biopsy and bone marrow examination failed to clarify its diagnosis. Renal biopsy revealed diffuse infiltration by atypical lymphoid cells in renal interstitium. Immunoperoxidase studies demonstrated this case was non-Hodgkin ＇ s lymphoma （NHL） of the B cell type through the renal biopsy.展开更多

Prostate localization is a rare entity. We report the case of a secondary prostatic localization of Burkitt lymphoma in a 14-year-old child. <strong>Observation:</strong> the 14-year-old child NNJ was followed at the Libreville Cancer Institute (ICL) for Burkitt maxillo-facial stage II bilateral Murphy lymphoma. The clinical examination noted an alteration of the general state, total hematuria, a voluminous prostatic mass filling the rectal ampoule. The paraclinical assessment noted renal insufficiency, a prostatic mass on ultrasound. Anatomo-pathological examination of the prostatic biopsy diagnosed Burkitt type non-Hodgkin’s malignant lymphoma. He died a week later. <strong>Conclusion:</strong> Primary or secondary prostatic lymphoma is rare. Obstructive renal insufficiency is an additional complication that darkens its prognosis by delaying etiological treatment based on polychemotherapy.展开更多
