Adenomatoid hyperplasia of mucous salivary glands. Report of two cases.

Adenomatoid hyperplasia of the mucous salivary glands is an uncommon benign tumor of the oral cavity. Two cases of palatal involvement are presented. Since clinical differentiation between benign and malignant growth of the palate cannot be established, microscopic examination is necessary. The palate is the most common location of this lesion, and as such it is useful for the periodontist to be aware of this tumor.
