摘要:This case report describes a 30-month-old child with primary pulmonary rhabdomyosarcoma with a congenital cystic adenomatoid malformation (CCAM). In the current literature, primary pulmonary neoplasms have been reported for similar cases. The tumor was located in the anterior-basal segment of the left lower lobe with a thin-walled cystic appearance and lobulated margins. A histology examination showed rhabdomyosarcoma origin with an embryonal subtype. Postoperative systemic chemotherapy was carried out. After a 6-month follow-up, the patient had no residual or recurrent disease.
