The retroperitoneal sarcoma and colonic carcinoma were resected simultaneously, while a hysterectomy was performed five months later. No genetic influence could be elicited in the present case. The synchronous triple primary, malignant neoplasms in this case should be considered as having arisen by mere chance. Other cases in which triple or more primary malignancies were resected are briefly reviewed. In addition, cases of triple or more primary malignant tumors with include at least one sarcoma are also reviewed.
