Adenomatoid hyperplasia of minor salivary glands: A case report in an unusual site

INTRODUCTION AND IMPORTANCE: Adenomatoid hyperplasia (AH) is an unusual entity which simulates salivary gland neoplasm. As suggested some lesions indicate reactive hyperplasia due to the chronic trauma by the ill-fitting complete dentures but here in the present case it's due to a fixed prosthesis. Here is an AHMSG occurring in a rare location that is in the lingual vestibule. Meticulous histopathological examination is an effective diagnostic tool to arrive in the diagnosis of AH. CASE PRESENTATION: A 60 years male patient with a lesion in the lingual vestibule of slow growth and an ulcer noted on the surface due to the trauma from the prosthesis. The patient was unaware of the growth and a provisional diagnosis made by the clinician was an irritational fibroma with traumatic ulcer but the final diagnosis turned to be AHMSG. DISCUSSION: The present case and previous case series suggest AH has a male preponderance. Histological analysis is a basic fundamental in arriving at a proper diagnosis. It's a 102-case added to the available web knowledge world-wide on AHMSG and the 4th case in India to be noted in the Indian literature. CONCLUSION: The differential diagnosis of the lingual vestibular placed exophytic lesions should include AHMSG.
