Intra-cystic papillary neoplasm of salivary gland with focal low grade malignant change: a rare entity.

Sohaila Fatima, Nazima Haider, Sabah Nayef Nemri, Balkur Krishnamoortthi Adiga

Abstract


Intraductal papilloma is a rare benign salivary gland tumor. It is found in the duct of the minor salivary glands, predominantly in lip and buccal mucosa, but the tumors in the sublingual region are quite rare.  Malignant counterpart of intraductal papilloma which is a well defined entity in WHO classification is also extremely rare. This report shows a case of borderline intraductal papillary tumor with low malignant potential. It developed in minor salivary gland of sublingual region. This is a very rare entity, not included in WHO classification of salivary gland tumors and needs to be distinguished from other more common papillary and cystic tumors found in salivary glands.
