Intraduct papilloma of the palate. Report of a case

Abstract

Salivary gland papillomas are rare tumours arising from ductal epithelium. Intraduct papillomas are the most rare of all duct papillomas. Only four intraduct papillomas have been described in a review of nearly 3100 epithelial salivary tumours. Intraduct papillomas are located almost exclusively in the excretory ducts of the minor salvary glands. However, also the major salivary glands may be affected. Microscopically, the tumour consists of fibrovascular papillae covered by a columnar or cuboidal epithelium. The authors describe an intraduct papilloma of the palate in a 74-year-old woman. The excision of the lesion was curative.
