title: Aggressive Calcifying Epithelial Odontogenic Tumor of the Maxillary Sinus with Extraosseous Oral Mucosal Involvement: A Case Report.
abstract: Calcifying epithelial odontogenic tumors are benign odontogenic neoplasms whose occurrence in the maxillary sinus is rare. Maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures. We report a case of a large calcifying epithelial odontogenic tumor of the maxilla, involving the maxillary sinus in a 48-year-old woman. The tumor was largely intraosseous. In the canine and first premolar regions, the loss of bone could be palpated but the oral mucosa appeared normal. Histologically, the tumor tissue could be seen in the connective tissue below the oral epithelium. The most significant finding was the presence of an intraosseous tumor with an extraosseous involvement in a single tumor, indicating aggressive behavior and warranting aggressive treatment. In this article, we discuss the rare presentation of the tumor and its radiological appearance and histological features. We also highlight the importance of a detailed histopathological examination of the excised specimen.
