Adenomatoid Hyperplasia: Case Report of a Rare Lesion in Uncommon Location

Abstract

Adenomatoid hyperplasia is a rare lesion of the minor salivary glands recognized by localized swelling that mimics a neoplasm. This so called pseudotumor usually occurring in adults 4th to 6th decade of life mostly, in 80 percent, occurs as a unilateral swelling without ulcer on the hard and soft palate. The pathogenesis of this condition is not well known but local trauma might have a role. In this case report three cases of adenomatoid hyperplasia have been reported to bring attention to this lesion as it is clinically similar to many soft tissue lesions of oral mucosa so should be considered while making a clinical diagnosis. Also, Pathologists should investigate a proper sample size under a microscope not to confuse a normal salivary gland adjacent to salivary gland tumours with Adenomatoid hyperplasia.
