Hairy polyps of the nasopharyngx are rare congenital tumoursmanifested after delivery by symptoms of acute respiratory obstruction or difficult swallowing. The authors describe two cases of hairy polyp, one neonate with intermittent acute dyspnoea with facial stigmatization and congenital dysplasia, the second neonate with symptoms of gastrooesophageal reflux. These rare congenital tumours are pendular and may threaten the infant’s life. The authors present a review on congenital tumours of the nasopharynx and possibilities of prenatal diagnosis. According to most recent data and the used pathological terminology it would be better to divide congenital nasopharyngeal tumours of neonates into 1. dermoid or teratoid tumours (formed by tissue of ectodermal and mesodermal origin without the presence of the neuroectodermal component where also hairy polyps belong), 2. teratomas (formed by ectodermal, mesodermal and endodermal, derivatives) which are classified according to the degree of differentiation into mature - benign and immature - malignant and 3. epignathus also known as „foetus in foeto“.
