title: Odontogenic tumor with prominent clear cell component misdiagnosed as pleomorphic adenoma by fine-needle aspiration. A case report.
abstract: Clear cell tumors in the maxillofacial region, are usually originated in salivary or odontogenic tissues, or may be metastatic. They include calcifying epithelial odontogenic tumors, ameloblastoma and odontogenic carcinoma. Clear cell odontogenic tumor has been classified in the last WHO classification as a benign tumor, but current opinion is that it should be designated as a carcinoma. We report a case of clear cell odontogenic tumor documented by histology, in a 82 year-old female, misinterpreted as pleomorphic adenoma by fine-needle aspiration cytology.
