Epistaxis refers to bleeding from the nose and is a common complaint with both adults and children. The exact incidence is hard to determine as most cases are minor and patients do not seek treatment. Patients may complain of per-oral bleeding or bloodstain sputum as well since blood can flow backwards and down the throat.

Occasionally, epistaxis may herald uncommon conditions such as the following:
