title: [A case of anisosynchronously duplicated tumors consisting of leiomyosarcoma of the rectum and malignant paraganglioma of gluteal soft tissue].
abstract: A 62-year-old man received a Miles' operation for the recurrence of low grade rectal leiomyosarcoma which had been enucleated 8 years earlier. The tumor, measuring 11 x 12 cm, was located in the lower rectal area (Rb) and had developed into the pelvic cavity. One year after operation, after the uncovery of a malignant paraganglioma in the right gluteal soft tissue, the patient died from the metastases of the liver and the lung, and from lymph node that covered his body. This case is a rare example of anisosynchronously occurring duplicated carcinomas.
