Primary Pulmonary Rhabdomyosarcoma in a Child

Area of Science:

• Pediatric Oncology
• Thoracic Surgery
• Diagnostic Imaging

Background:

• Rhabdomyosarcoma (RMS) is a rare pediatric malignancy.
• Primary pulmonary RMS is exceptionally uncommon, often presenting with non-specific symptoms.
• Congenital pulmonary airway malformations can sometimes obscure initial diagnoses.

Observation:

• A 9-year-old female presented with fever, cough, and hemoptysis.
• Imaging revealed a right lower lobe lesion with features suggestive of congenital pulmonary airway malformation.
• Surgical resection was performed, followed by histopathological confirmation of rhabdomyosarcoma.

Findings:

• The resected lesion was confirmed as a primary pulmonary rhabdomyosarcoma (RMS).
• No evidence of a primary tumor at other sites was found.
• The patient remained disease-free for 6 years following adjuvant chemotherapy and surveillance.

Implications:

• This case underscores the importance of considering rare malignancies in pediatric lung lesions.
• Early diagnosis and surgical management are crucial for favorable outcomes in primary pulmonary RMS.
• Further research into the clinicoradiological presentation of primary pediatric lung tumors is warranted.
