Chromosomal aberrations in adenomatoid hyperplasia of palatal minor salivary gland.

Adenomatoid hyperplasia of minor salivary glands is rare, idiopathic, and benign, and typically presents as a tumour-like mass in the hard or soft palate. Its exact nature is not clear and histological examination usually shows an excess of normal-appearing minor salivary glands. To our knowledge, cytogenetic analysis of it in a minor salivary gland of the palate has not previously been reported. We present the cytogenetic analysis of adenomatoid hyperplasia in the hard palate of a 52-year-old woman.
