A case of bilateral testicular lymphoma.

Authors report on a 75-year-old man with bilateral testicular lymphoma. He complained of painless right testicular enlargement. Orchidectomy was indicated by ultrasound examination and the diagnosis (large cell, non-Hodgkin lymphoma B-cell origin) was established by histology and immunohistochemistry. Two months later, the left testis enlarged, orchidectomy was performed, and a lymphoma with identical histology was found. PET revealed retroperitoneal spread of the tumor. Irradiation (18 Gy) was applied. Three months later, because of gastric metastases of the lymphoma the patient underwent CVP and CAVP (Cyclophosphamide, Adriablastin, Vincristin, Prednisolone) chemotherapy. Despite of the repeated courses, eleven months after the primary diagnosis the patient died due to of multiple metastases.
