title: Osteosarcoma with deeply eosinophilic rhabdomyoblast cells in a lung metastatic focus. A case report.
abstract: In a ten-year-old boy with left femoral osteosarcoma, the diagnosis of osteosarcoma was established through bone biopsy. Chemotherapy was administered, but episodes of recurrence and metastasis occurred. In July 1989, a second lung metastatic focus was resected. Histopathologic examination of this metastatic focus showed widespread cross-striation together with osteoid formation. A comparable case seems not to have been reported in the literature.
