ABSTRACT
Oxyphilic adenomas are unusual neoplasm of the head and neck region affecting the glandular epithelial tissue. They were first called as oncocytoma, which is composed of oncocytes and were first described by Schaffer and Hamperl. Oncocytes are polyhedral cells and contain abundant cytoplasm filled with eosinophilic granules. Oxyphilic adenomas are benign neoplasm and represent approximately less than 1% of all salivary gland tumors. They are found generally in the parotid gland, affecting parotid gland region extraorally and rarely encountered in various other sites. Involvement of floor of the mouth is very rare. Presented in this article is a case report of patient suffering from neoplasm, which was histopathologically diagnosed as oxyphilic adenoma.
