An Exuberant Calcifying Epithelial Odontogenic Tumor in the Posterior Maxilla: A Case Report.

This case report presents a rare instance of a Calcifying Epithelial Odontogenic Tumor (CEOT) in the maxilla of a 52-year-old male, characterized by a painless, growing mass and facial asymmetry. Imaging revealed extensive involvement of the maxillary sinus, nasal cavity, pterygoid plate, and infraorbital margin. Histopathological analysis confirmed the diagnosis, showing polyhedral odontogenic epithelium with amyloid-like material. The patient underwent conservative surgical excision, preserving function and aesthetics, with no recurrence observed at 16 months postoperatively. This case underscores the importance of a multidisciplinary approach in managing CEOT, particularly in complex anatomical regions, to achieve favorable outcomes. Long-term follow-up remains essential. Calcifying Epithelial Odontogenic; Pindborg tumor; CEOT; maxilla; odontogenic tumors.
