Osteosarcoma--presumed lymph node metastases in two cases.
Two patients with osteosarcoma of a lower limb and presumed lymph node metastases are described. The metastases presented in both children as palpable masses, one in the inguinal region and the other in the pelvis. One was visible on plain radiography; both were demonstrated on computed tomography and bone scintigraphy. The inguinal mass was present at the first examination and was resected with the primary lesion. The pelvic mass presented 12 months after amputation and was unresectable; its subsequent rapid growth was demonstrated by computed tomography. In one patient the osteosarcoma was of the osteoblastic type.
