[Leiomyosarcoma of the spermatic cord: a case report].

A 63-year-old man presented with painless hard swelling of left scrotal contents. Left orchiectomy with high ligation of the spermatic cord was done with clinical diagnosis of testicular tumor. Histopathologically, this tumor was diagnosed as leiomyosarcoma, primarily, arising from the spermatic cord. After operation, prophylactic radiotherapy (60Co, 5,890 rad) was given locally. There has been neither local recurrence nor metastasis for 10 months after operation. This is the 18th case of leiomyosarcoma of the spermatic cord in Japan.
