Adenomatoid hyperplasia of mucous salivary glands: a case involving the retromolar area.

This case report describes an unusual salivary gland lesion that involved the retromolar area. This lesion presented clinically as an asymptomatic tumorlike nodule that was characterized microscopically by a proliferation of mucous salivary gland tissue. The exact nature of this focal enlargement of accessory salivary gland tissue is not known. Because this lesion cannot be distinguished clinically from a salivary gland neoplasm, it must be excised and examined microscopically.
