The hairy polyp is a rare congenital tumor. We introspected 7 cases of hairy polyp that were operated on in our hospital. Microscopically, they all contained only ectoderm and mesoderm tissue and the surface of tumors covered skin and hair regularly. One patient died of a hemorrhage and one girl`s hairy polyp occurred in nose. The result indicates that age, pedicle and thin hair are significant markers for the differential diagnosis of hairy polyp and it is important to closely follow a patient post operatively not only for airway obstruction but also hemorrhage.
