Multiple primary malignant neoplasm of the combination of the musculoskeletal system and the gastrointestinal system were very rare. A case of synchronous double primary malignant neoplasm consisted of myxofibrosarcoma of forearm and adenocarcinoma of rectum in a 52 year-old man was found. The patient had pain and swelling on forearm for 1 year. Histologically, the lesion on forearm showed myxofibrosarcoma. In systemic evaluation, the adenocarcinoma of rectum was found by the sigmoidoscopy, and metastasis on lung and intracardiac mass were found by the CT scan. We performed surgical excision and pre and postoperative chemotherapy after pathologic confirmation. He died of pulmonary thromboembolism after postoperative 2 months. We report this case of exceedingly rare combination of the musculoskeletal system and the gastrointestinal system.

Primary cardiac tumor has very low incidence, especially in cases of malignancy. A 29 year old male patient visited our cardiologic clinic for recent aggrevation of dyspnea on exertion and palpitation. Echocardiography showed a large tumor in the left atrium, which suggested the left atrial myxoma. Urgent open heart surgery was taken. The operative finding was fossa ovalis based a large tumor (35$\times$90$\times$50 mm) that invaded the posterior wall of LA and right superior pulmonary vein directly. The tumor was excised well by simple dissection, and the final pathologic report was malignant myxofibrosarcoma. His postoperative course was smooth and he was discharged in good health. Postoperative radiation and chemotherapy had taken with satisfactory clinical outcome.

Primary cardiac tumors are known to be rare. We studied the surgical results for primary cardiac tumors. Material and Method: Between August 1980 and December 2003, we classified 86 patients who had operation for primary cardiac tumors in our center into 3 groups; myxoma, nonmyxoma benign tumors, and malignant tumors. The mean age was $44.3\pm20.8$ years and 59 patients $(66.3\%)$ were female. In postoperative pathologic diagnosis, there were 81 cases $(94.2\%)$ of benign tumors in which myxoma was the most common tumor $(70\;cases,\;78.7\%);$ 5 fibroma $(5.6\%)$, 3 rhabdomyoma $(3.4\%)$, and 5 malignant tumors $(5.8\%)$. Result: $86.4\%$ of benign tumor was myxoma and the mean age was $50.4\pm15.4\;(range\;7\~80)$ years. Tumor was more common in females (49 cases) and most common preoperative symptom was dyspnea $(62.9\%)$. 57 cases were located at left atrial septum and only one case, which was located at right ventricular septum, was resected incompletely. There were no hospital deaths and one patient had mitral valve replacement on the first operative day due to newly developed postoperative mitral regurgitation. The mean follow up period was $109.3\pm71.8$ months and there was no evidence of recurrence in this period. 11 cases $(12.8\%)$ were non myxoma benign tumors; 5 fibromas, 3 rhabdo-myomas, etc. There were two hospital deaths and the causes of death were fungal endocarditis and hypoxia. There were no reoperations in nonmyxoma benign tumors. Malignant tumors were in 5 cases $(5.8\%);$ undifferentiated sarcoma in 2, rhabdomyosarcoma in 1, etc. Although there were no hospital mortalities, 3 patients who were followed up died from complications of tumors. Conclusion: Myxomas showed very excellent prognosis after complete resection and nonmyxoma benign tumors showed relatively good results for relief of symptoms. Surgery helped to relieve symptoms for malignant tumors, but the prognosis was poor.
