Osteosarcoma lymph node metastasis are uncommon. This paper shows two patients having osteoblastic osteosarcoma with loco-regional lymph node involvement. In the first case two inguinal and pelvic adenomegalies were found to have tumor metastasis two years and a half after initial diagnosis in a control radiological study.
Currently the patient is alive three months after the lymphadenectomy. In the second case, several inguinal high density tumoral nodules were identified during the workup of primary tumor.
