title: [A case of malignant lymphoma with the chief complaint of right intrascrotal tumor].
abstract: A 65-year-old male visited the Sawara Hospital with the chief complaint of right intrascrotal mass. The mass without tenderness, in which right testis and spermatic cord appeared to be involved, reached the right inguinal region. Right high orchiectomy was performed under the diagnosis of a testicular tumor. Histological diagnosis was malignant lymphoma. Intravenous pyelogram revealed right hydronephrosis and 67Ga-scintigram showed an abnormal accumulation of radioisotopes in the pelvic and paraaortic region. Chemotherapy with vincristine, cyclophosphamide, 6-mercaptopurine and prednisolone was performed under the diagnosis of stage IV lymphoma. Two months after chemotherapy, right hydronephrosis disappeared and no abnormal accumulation in 67Ga-scintigram was found. He has been doing well three months after treatment.
