ABSTRACT

Introduction: Ameloblastoma is a benign but locally invasive neoplasm generally diagnosed in the fourth and fifth decades of life. Its location is the mandible in 80% of the cases and the maxilla in 20%. Histopathologically, it may be classified as follicular, plexiform, acanthomatous, granular cells or basal cells. Desmoplastic ameloblastoma has been further classified as a histological subtype. Radiographically, it presents as either unicystic or multicystic, in which case it resembles a honeycomb or soap bubbles.
Objective: Describe a case of ameloblastoma with uncommon clinical and imaging characteristics.
Case presentation: A white female 72-year-old patient from the city of Itabaiana, Sergipe, presented with increased volume (of slow development) in her anterior mandibular region. Computed tomography revealed a hypodense, multiloculated area in the anterior mandibular region. Incisional biopsy and imaging tests were performed. The diagnosis was follicular ameloblastoma with a broad area of cystic degeneration. It was decided to perform total excision of the lesion. A circular bone housing was formed, which was treated with Carney’s solution.
Conclusions: The present report is of great relevance, since a case is described which contradicts the existing facts and points to the importance of making a correct diagnosis. Although the behavior of oral cavity lesions is well known, it is extremely important to continue to study them.
