[Liposarcoma of the Spermatic Cord : A Case Report and Review of the Literature].

A 92-year-old man had noticed enlargement of a mass in the right scrotum and inguinal region for nine months. The patient was introduced to our department for right testicular tumor. Physical examination showed an over fist-sized, hard mass in the right scrotum. Magnetic resonance imaging (MRI) showed the mass, which consisted of fatty and solid contents. In addition, MRI revealed a bladder tumor simultaneously. Computed tomography revealed no distant metastases. The patient underwent right high orchiectomy with the mass resection and transurethral resection of the bladder tumor (TURBT). Pathological examination revealed well- and dedifferentiated liposarcoma of the right spermatic cord, and urothelial cancer of the bladder. Liposarcoma of the spermatic cord is a rare neoplasm. To the best of our knowledge, the present case was the 114 th reported case and oldest in Japan.
