Anorectal papillomas in rabbits are benign, well differentiated epithelial tumours of the anorectal junction. Their aetiology is unknown but they have not been associated with any papilloma viruses, and transmission experiments have been unsuccessfull. This chapter explains the relevant anatomy, and goes on to cover clinical signs, differential diagnosis and diagnostic procedures, treatment options and prognosis. Operative Technique: Surgical removal of anorectal papillomas.
