title: Two rare entities in the same palate lesion: hyalinizing-type clear cell carcinoma and necrotizing sialometaplasia.
abstract: Hyalinizing clear cell carcinoma is a low-grade malignant epithelial neoplasm of the salivary glands. The tumor has epithelial cells and lacks myoepithelial cells. Necrotizing sialometaplasia is a benign, self-limiting lesion of the salivary glands. The clinical and histologic features mimic those of mucoepidermoid carcinoma or squamous cell carcinoma. The importance of these entities are the rarity of both of them and their potential to be misdiagnosed as other lesions. Pathologists and clinicians should be aware of these entities to prevent misdiagnosis. This is the first clinical report of 2 rare and consecutive different entities of the same location on the hard palate to our knowledge.
