[Late results of ilio-inguinal lymphadenectomy in melanoblastoma of the skin of lower limbs].

Under examination were 3--5--10 year results of ilioinguinal lymphadenectomy in 83 patients with skin melanoblastoma of the lower extremity. It is found that the status of inguinal and especially iliac lymphnodes is of primary importance for patients' survival. The latter were metastases involved in 24 cases (28.9%). Metastases may also develop in intact inguinal lymphnodes (in 4 cases). A 3-year survival, if one group of regional lymphnodes is involved (inguinal or iliac), is 20% lower than in the intact noes. With both groups of the nodes involved it is 4 times lower. A 5--10 year survival with involved inguinal nodes is 2 twice as low as with intact nodes. In iliac lymphnodes metastases there was no 5-year survival. Most poor results were noted in melanoblastoma located on the foot.
