Solitary intraductal papilloma of the minor salivary glands.

A case of solitary intraductal papilloma of a minor salivary gland is presented. The lesion was diagnosed clinically as a mucocele and has not recurred in 6 months of observation. This case is compared, on the basis of clinical data and histomorphologic findings, to three other known cases. Discussion is made of the role this lesion might play in the etiology of ductal obstruction, and the histologic findings of the intraductal papilloma of minor salivary glands and the solitary intraductal papilloma of the breast are compared.
