title: Intraosseous pleomorphic adenoma: case report and review of the literature.
abstract: Pleomorphic adenoma is the most common neoplasm of the salivary glands, affecting mainly the parotid gland. The preferential intraoral site of this tumor is the palate. A case of a 31-year-old woman with an intraosseous pleomorphic adenoma located in the maxilla (left paramedian region), showing an approximate evolution of one year is reported. The present intraosseous case represents a rare location, with the tumor probably originating from glandular epithelial remnants captured during embryogenesis. In a review of the literature of 142 cases of intragnathic localization (24% in the maxilla) are identified. A slight predominance of women was observed (56%), with 55% of the patients being affected during the 5th to 7th decade of life. The tumors were malignant in 94% of the cases, with special predominance of mucoepidermoid carcinoma (65%). Intraosseous pleomorphic adenomas are rare, with the present patient being the 6th case reported in the literature and the second found in the maxilla. Mean age of the 5 previously reported cases was 58.8 years.
