title: [Sphenochoanal polyp. Diagnostic and therapeutic aspects].
abstract: BACKGROUND
  Sphenochoanal polyps (SCP) grow from the sphenoid sinus and occupy the nasopharynx.
  
  
  OBJECTIVE
  To describe the clinical and diagnostic features of SCP, reporting two cases. Epidemiological study of the series in the literature. 8 published series were found (22 cases).
  
  
  CONCLUSIONS
  SCP is a rare lesion that is usually misdiagnosed for antrochoanal polyposis. A proper diagnosis and surgical treatment are the basis to prevent recurrence. We describe the first case of SCP with cacosmia.
