In 1954, Kinmonth & Taylor demonstrated lymphatic system by intralymphatic injection of contrast material. The large number of studies were accumlated to this method experimentally and clinically. It is commonly proved that the lymphography is useful to diagnose a lymphatic metastasis.
We performed lymphography in five cases which were Fibrous dysplasia, Haemoangioma, Fibroma, Myxofibrosarcoma and Osteosarcoma. The results are presented here.
1) A lymph node of benign tumor maintains normal size and architectual pattern (Fibrous dysplasia), or increases in node size and number without abnormal pattern (Haemoangioma and recidivation of Fibroma).
2) A case of recidivative Myxofibrosarcoma after ⁶⁰Co therapy, reveals peripheral filling defects of lymph node and stagnation of afferent vessels by lymphography, but histologically fibrosis and atrophy are observed without lymph node metastasis.
3) A case of Osteosarcoma, 71 years old man, in spite of abnormal pattern by lymphography, demonstrats no lymph node metastasis histologically. Following the report by Malamos, a lymph node of old age reveals fatty degeneration and fibrosis, resulting a abnormal lymphatic pattern.
4) It is reported that the reactions of lymph node following lymphography are slight. By microradiography we observed a considerable number of defects which were filled by contrast material in lymph node and concluded that lymphography affected lymph node deeply morphologically.
