An elastic hard mass was palpable in the right inguinal region next to the spermatic cord. Ultrasonography and computed tomography showed an inguinal homogeneous mass which was slightly enhanced. Since the operation appearance indicated the tumor was arising from the right spermatic cord, right radical orchiectomy was performed. Histopathological examination revealed a well-differentiated liposarcoma of the right spermatic cord. This is the 70th case of liposarcoma of the spermatic cord reported in Japan
