A Case of Intrascrotal Liposarcoma

: A 69-year-old man was referred to our hospital with the chief complaint of a painless right scrotal swelling gradually increasing in size during the past 10 years. Testicular tumor markers were within the normal range. Ultrasonography showed an intrascrotal homogeneous mass. Computed tomography and magnetic resonance imaging revealed an inguinal mass, which mainly consisted of fat signal area and partially well enhanced in vascular density. Pre-surgical diagnosis was liposarcoma of spermatic cord estimated by radiographic examination and resection of the right intrascrotal tumor with high inguinal orchitectomy was performed. Histopathological diagnosis revealed well-differentiated liposarcoma. No recurrence phenomenon has been observed after 12 months without any adjuvant therapy. This case is the 129th report of intrascrotal liposarcoma in the Japanese literature.
