Abstract
The upper airway obstruction by pharyngeal tumor is very rare in infants. We present a girl of neonate who showed inspiratory stridor, ingestion disoder and failure to gain weight. On otolaryngological examination, pediculate tumor existed on retropharynx. We resected the tumor at stalk under general anesthesia with intubation, because we worried that it was possible that the tumor suddenly impacted in inlet of larynx. The tumor was covered with normal mucosa and included chondral tissue. We wondered whether the tumor was a cervical rib that was a congenital anomaly.
Judging from a point of anatomical and embryological view, there is a possiblity that this is a case of cervical rib. When we differentiate the cause of neonatal respiratory disoder, we should consider a congenital tumor including cervical rib.
