Anal Papilla or Anal Polyp

Anal papillae are small protrusion of the anal canal skin, where the latter end pushes upwards towards the rectal mucosa, and are located at the dentate line level, frequently at the top of it or on the sides of the valves of Morgagni. Their dimensions may vary from 1-5 mm. They can be distinguished from a polyp by testing their sensitivity. One or more papillae can undergo hypertrophy, becoming elongated to 1-4 cm in length with fibrous thickening, assuming the appearance of the fibrous polyp. At such time the hypertrophic anal papilla can become symptomatic, protruding from the anal orifice during defecation.
