Primary tracheal neoplasms in children, especially malignant lesions, are e
xtremely rare. We report a unique case of low-grade mucoepidermoid carcinom
a of the trachea in a 4-year old child, presenting as new-onset asthma. Usi
ng the ventilating resectoscope, endoscopic excision was accomplished witho
ut complications. The case is presented with documentation including airway
films, endoscopic photographs, and histopathology. The diagnosis of trache
al masses depends upon maintaining a high index of suspicion, complemented
by imaging and timely diagnostic endoscopy. A review of the literature is i
