title: An uncommon case of simultaneous malignant tumors: bronchioloalveolar cancer and Ewing's sarcoma in a 17-year-old girl: report of a case.
abstract: This report describes a 17-year-old girl with a simultaneous occurrence of bronchioloalveolar cancer and Ewing's sarcoma of the femur, which is a previously unreported association. This case emphasizes the existence of multiple primary malignant neoplasms even in adolescents. Primary lung cancer should therefore be considered in patients under 19 years of age who present with abnormal pulmonary lesions.
