title: Age and sex incidence of hypopharyngeal tumours in upper Egypt: Assuit University experience.
abstract: Three hundred and seventeen patients with hypopharyngeal tumours presented at Assuit University Hospital and were studied retrospectively with regard to sex and age incidence. Postcricoid tumours form the majority (50.1 per cent) followed by pyriform fossa tumours (26.5 per cent) and finally posterior pharyngeal wall tumours (23.4 per cent). Men form the majority (211 out of 317, i.e. 69.7 per cent). The age incidence shows two peaks at 31-35 years and 56-60 years. The first peak is formed mainly of women while the second peak is formed mainly of men.
