He subsequently developed hemoptysis prompting computed tomography that revealed a 3.6 x 3.9 x 4.9 cm mass within the wall of the trachea that caused critical narrowing of the trachea ( Fig. 1 ). 
Pathology. Nests of monotonous round cells with pale eosinophilic cytoplasm and thin-walled vessels containing focally infiltrating smooth muscle (hematoxylin/eosin, 20 x).
