[A malignant lymphoma of the testis relapsed in the contralateral scrotal skin after the radiation therapy: a case report].

A 71-year-old man was admitted with a swelling of the left scrotum where Galium scintigraphy was positive. He had a history of malignant lymphoma of the right testis and had undergone an orchitectomy, with adjuvant CHOP (cyclophosphamide, doxorubicin, vincristine, predonisolone) chemotherapy and radiotherapy to the post-orchitectomy site and opposite testis. An open biopsy of his scrotum and left testis revealed relapse of the malignant lymphoma in the left scrotal skin.
