Metastatic melanoma involving the colon 总被引:1,自引:0,他引:1
Dr. James H. McClenathan M.D. 《Diseases of the colon and rectum》1989,32(1):70-72
A patient with isolated cecal metastasis of malignant melanoma whose symptoms of fatigue, exertional dyspnea, and an abdominal mass were relieved by operation is reported. Palliative resection appears to offer significant benefit in patients with symptomatic melanoma involving the colon, particularly if the lesion is solitary. 相似文献

A 62-year-old man had been followed because of an elevated serum level of carcinoembryonic antigen without the detection of any cancer lesions. However, there was a sudden increase in the serum level of carcinoembryonic antigen, and abdominal imagings showed a hepatic tumor with peripheral intrahepatic bile duct dilatation, and a submucosal tumor at the sigmoid colon with intact mucosa. Histopathological findings showed that the hepatic tumor had perineural invasion, suggesting an intrahepatic cholangiocarcinoma, and that the colon tumor infiltrated the submucosa, while its mucosa was intact. Both tumors showed similar pathological features and were positive for cytokeratin 20 and 7. These findings suggested intrahepatic cholangiocarcinoma with metastatic sigmoid colon cancer. 相似文献

Summary Metastatic colon carcinoma of the heart is a rare diagnosis, and an uncommon finding at autopsy. This report describes a patient with a huge intracavitary colonic metastasis of the right atrium causing both a superior vena cava syndrome and an obstruction of the tricuspid valve. To our knowledge, no similar case has been previously reported. 相似文献

Metastatic disease involving the stomach is an unusual and difficult clinical problem. A review of 1010 autopsies of patients with cancer disclosed 17 cases of gastric metastases (an incidence of 1.7%), with breast cancer, lung cancer, and melanoma being the most frequent primaries. The clinical manifestations of epigastric pain, melena, and anemia are nonspecific, necessitating radiographic examination of the gastrointestinal tract. The radiographic findings are usually sufficient to suggest the diagnosis. 相似文献

In reporting a case of haemangiosarcoma of the right atrium the authors emphasize the problems encountered in the diagnosis of primary tumours of the heart. The patient was a 50-year old woman who complained of digestive disorders and palpitations. Physical examination showed signs of right heart failure associated with a systolic murmur on the right side of the sternum. ECG gave normal results. Echocardiography displayed a pouch with liquid ultrastructure communicating with the right atrium. Angiography confirmed the presence of a cavity with irregular borders communicating with the right atrium. Coronary arteriography showed an abnormal disorderly distribution of the right coronary artery branches with newly formed vessels extending toward the tumour. At exploratory thoracotomy a large liquid tumour was found which bled at the slightest touch and was attached to the mediastinum and the right pericardium. The pleura and the lung contained several nodules of the same venous colour as the mother tumour. Extemporaneous biopsy and pathological analysis were in favour of a haemangiosarcoma. The patient died a few days after the thoracotomy. 相似文献

The increasing ratio of proximal to distal colorectal carcinomas was confirmed in this population-based study of 668 new cases diagnosed among Rochester, Minnesota residents between 1940 and 1979. The change was due to a rise in the incidence of proximal lesions (from 15.1 per 100,000 person-years in 1940–59 to 17.3 per 100,000 in 1960–79) and a simultaneous fall in the incidence of distal lesions (from 35.5 to 28.2 per 100,000 person-years). Changes in definitions or referral patterns played no role in these observations, although improved diagnostic capabilities may have had an impact on the incidence of proximal lesions. These discrepant changes in incidence strongly suggest that proximal and distal colonic cancers are different diseases or have a different pathogenesis. The changing incidence rates were not associated with consistent differences in clinical characteristics at the time of initial diagnosis. 相似文献

A metastatic synovial sarcoma in the right atrium and ventricle is described. A 36-year-old man was admitted to our hospital with generalized fatigue, dyspnoea, and precordial pain. Transthoracic echocardiography demonstrated a metastatic tumour in both the right atrium and right ventricle and revealed obstruction of the inflow tract of the right ventricle caused by a metastatic right atrial tumour. Thoracic computed tomography revealed a pleural-based paravertebral mass in the left intrathoracic cavity and multiple pulmonary nodules in both lungs. Cardiac surgery was performed for palliative treatment due to right cardiac failure and a risk of fatal embolization. The patient died 12 months after the cardiac surgery. 相似文献

A 68-year-old female patient was referred for the evaluation of an incidentally detected asymptomatic cardiac mass. Imaging studies showed a 3.0 x 2.4 cm, well circumscribed, round, cystic mass with a calcified nodule that was attached to the lower rim of the fossa ovalis in the right atrium. Under cardiopulmonary bypass, the right atrium was opened to reveal a well circumscribed, dark bluish, pedunculated mass. Histologically, the specimen was a unilocular cyst lined by flattened endothelium, with peripheral fibrin clots and dystrophic calcification of the wall. Immunohistochemical staining of the lining cells was positive for cluster designation 34, which represents hematopoietic progenitor cell antigen. The final pathologic diagnosis was compatible with varix of the heart, which should be considered for a cystic mass with a calcified nodule located in the right atrium, near the lower rim of the fossa ovalis. 相似文献
