Urinary retention due to prostatic involvement in testicular lymphoma: a case report

Testicular involvement was the first manifestation of malignant lymphoma in the present case; after six months the disease became generalized but repeated chemotherapy achieved amelioration with negative bone-marrow biopsy after one year. Then urinary retention appeared, due to prostatic involvement from primary testicular lymphocytic lymphoma. We believe that this is the first reported case of primary malignant lymphoma of the testicle with secondary localization to the prostate and acute urinary retention.
