High-grade pulmonary mucoepidermoid carcinoma supplied by the pulmonary artery and vein in a 6-year-old child: a case description and literature analysis

[摘要] Primary pulmonary mucoepidermoid carcinoma (PMEC)originates from ductal epithelial cells in the submucosa of thetrachea and bronchus and accounts for fewer than 1% of allprimary lung malignant tumors(1). PMEC is also a primarylung cancer in children but extremely rare. Generally, PMECin children is classified as low grade, and the high-gradesubset is uncommon (2). However, in the relevant literature(3,4), the blood supply of PMEC was not extensivelyinvestigated. We here report a case of a 6-year-old childwith high-grade PMEC supplied by the pulmonary arteryand vein, mimicking pulmonary arteriovenous fistula andpulmonary sequestration.
