Metastasis of sarcomatous lesion in regional lymph node

This is a retrospective study of 390 patients with early sarcoma admitted over a 13‐year period. There were 182 bone lesions, 173 soft tissue sarcomas, and 35 visceral sarcomas. Two hundred ninety‐two patients had surgical resections, and 77 had specimens of lymph node(s) examined histologically. Among the latter group, 6 of 47 patients with non‐osseous sarcomas (13%) had metastasis in the regional node initially (subtypes include fibrohistiocytoma, leiomyosarcoma, rhabdomyosarcoma; synovial, anaplastic, and Kaposi sarcoma). Another two patients developed nodal metastasis subsequently (rhabdomyosarcoma). Among the 30 patients with skeletal sarcomas who had lymph nodes removed during resection, one case with osteogenic sarcoma and one chondrosarcoma had nodal metastasis initially (7%). During follow‐up, one patient with Ewing's sarcoma and another with chondrosarcoma developed regional lymphadenopathy. Our findings are discussed and compared with incidences of metastatic sarcomatous lesion in lymph node reported in the literature.
