Even supposing far away metastases are the main dreaded state of affairs within the evolution of melanoma of each organ, the scientific literature has strangely given little awareness to the anatomical courting among the first tumor and metastasic websites. basically hazard elements, therapy probabilities, and survival effects are generally tested. motivated by means of the prevalence in his perform of a few perplexing and unforeseen metastases, the writer reviewed greater than 12,000 references. He sought for anatomical relationships highlighting the relation among the site of the first tumors and the actual styles of metastasis saw. it'll appear that the `pathways and flows' are it appears a extra decisive think about the implantation of the metastases than the `seed and soil' houses of the melanoma cells and the metastatic website. Aided through his colleague Dr. T. Geukens, M.D., the writer contains unique anatomical drawings, illustrating the occasionally unforeseen pathways the melanoma cells stick with with a purpose to succeed in the organs the place they're going to turn into lodged and provides upward thrust to metastatic tumors. the topic has it sounds as if now not been exhausted within the literature and several other principles are given for additional examine.

Found 12 reports in the literature, adding two cases. More than half were from bronchial cancers. Neoplastic emboli obstructed the epicardial coronaries in nine and the intramural in three patients. The left coronary system was the site in 83% of the involved vessels. The clinical presentation is commonly a myocardial infarct but as the emboli can be diffuse and small, somewhat aspecific complaints and ECG-signs are common. astinal invasion with occlusion of the lymphatics. Special Situations Cardiac metastases have been described as occurring with other anatomical presentation and must be mentioned.
The ventricular wall is thicker, an hypo or akinetic at this level. The transmural invasion modifies the epicardial and endocardial contours, allowing differential diagnosis with thrombi. CT will delineate the status of the heart and of the mediastinum. Diagnosis In making the diagnosis, the most important thing is to have an awareness of the possibility of cardiac metastases in a cancer patient. If radiology and ECG have played a minor role previously, two-dimensional echocardiography is the method of choice to reveal any metastasis, its extension and complications.
The lymphatics of the diaphragm are in contact with abdominal and thoracal lymphatics by numerous anastomoses. Like many organs, the diaphragm can be invaded either by contiguity from neighbouring primaries as liver, stomach, pancreas and transverse colon, or through vascular (hematogenous) spread. , involving 198 patients with soft-tissue metastases, of whom 68 had diaphragmatic metastases. 68). The data clearly show that the pleural surface alone is rarely involved in infradiaphragmatic tumors.
