title: [Metachronous primary malignant lymphoma of the bilateral tests: a case report].
abstract: We report a case of metachronous malignant lymphoma of the bilateral testes. A 62-year-old man presented with a mass in the right scrotal contents. Physical examination revealed a solid painless mass in the right scrotal contents measuring 4 cm in diameter. He underwent right high orchiectomy. The histological examination confirmed non-Hodgkin's lymphoma of diffuse, large-sized cells of the B cell type. Computed tomography of the abdomen revealed paracaval lymphandenopathy at stage IIE according to Ann Arbor classification. Chemotherapy was initiated with cyclophosphamide, adriamycin and vincristine. Eleven months after the initial operation, the patient complained of left scrotal swelling, and subsequently underwent left high orchiectomy. The histological examination revealed the same pathology as observed in the right one scrotal contents. He was free from recurrence at 15 months after the second operation.
