[Secondary prostatic lymphoma in a kidney transplant patient].

Lymphoma involving the prostate is rare, both as a primary and as a secondary presenting. Usually the prognosis remains poor. The clinical presentation is similar to that of other lower urinary tract obstructions, in fact prostatic lymphoma must be considered in patients with these symptoms, particularly in patients with prior history of systemic lymphoma. We report a case of a kidney transplantation in a male patient, diagnosis of lymphoma non Hodgkin, with later recurrence in prostate.
