Evolución clínica de un Tumor Odontogénico Adenomatoide en maxilar. Reporte de caso. TOA. Reporte de caso

ntroduction. The Odontogenic Adenomatoid Tumor (TOA) is a rare entity that does not affect neighboring structures but only expands cortices. The WHO in 2005 classified it as an Epithelial Odontogenic Tumor. Case report. A 13 years old male patient, with volume increase that generates deformity in the right side of the maxillary and the nose; the tumor was causing respiratory difficulty, presented slow and gradual growth, and it was painless since it only generated pressure. It began as a clinical intraoral lesion of approximately 5 mm in diameter. Back then, it was managed with analgesics, and two months later, through an incisional biopsy and histopathological study, it was diagnosed as TOA. Fourteen months later, a tomography was taken, and a well-defined hypodense image with a hyperdense halo of approximately 4 cm in diameter was observed in the right maxilla with external cortical expansion, without apparent invasion of the maxillary sinus. The tumor was related to the superior displacement of the dental organ (OD) 13. Under surgical protocol and general inhalation anesthesia, the tumor was enucleated, and OD 13 was extracted. Microscopically at 10X, dense fibrous connective tissue stroma, characterized by the presence of spindle cells arranged in a nodular pattern, accompanied by ductal structures in whose interior eosinophilic material with some calcifications was observed. A 40X gland-like structure surrounded by spindle cells. The diagnosis concurred with an Adenomatoid Odontogenic Tumor
