Sialocystadenoma papilliferum of the palate.

The clinical and histological data concerning a case of sial -( ocyst )-adenoma papilliferum of the palate are presented. Ten cases of sialadenoma papilliferum have been reported to date. The lesion is characterized by several distinct clinical and histological features resembling in many aspects the syringocystadenoma papilliferum of the skin. Because of the invariable presence of more or less cystically dilated salivary gland ducts we propose to denote the lesion as sialocyst -adenoma papilliferum. Generally these neoplasms behave as benign tumours with an indolent and asymptomatic clinical course, although a single case of a malignant counterpart has been reported. An adequate local excision seems to be the treatment of choice. An accurate follow-up is required.
