Fibrovascular polyp of the hypopharynx.

Ann Saudi Med 28(3) May-June 2008 www.saudiannals.net 217 Fibrovascular polyps are extremely rare benign neoplasms of the hypopharynx that can arise from any site in the pharynx.1,2 Because of the mixture of stromal tissues, it is hypothesized that the fibrovascular polyp may be a hamartoma or an unusual type of inflammatory polyp. Another theory is that they arise secondary to mucosal injury,3,4 gastroesophageal reflex or ectopic gastric mucosa.5,6 To our knowledge, this is the first report in the Middle East of an extremel ly rare case of fibromatous polyp in the hypopharynx arising from the piriform sinus mucosa.
