Adenoid Ameloblastoma in the Posterior Maxillary Region: A Case Report

ABSTRACT Objective Adenoid ameloblastoma (AA) is a recently described subtype of ameloblastoma that poses a diagnostic challenge and carries a potential risk of infiltration and recurrence. We aimed to report an AA located in the posterior maxillary region, treated by marginal resection, with an excellent postoperative result. Methods A 46‐year‐old female presented with a 5‐month evolution asymptomatic tumour located in the right maxilla, extending from the first molar region to the tuberosity. Medical history was non‐contributory. Incisional biopsy revealed adenoid ameloblastoma. The lesion and associated teeth were resected with a 1.5 cm margin. Result After 5 years of marginal resection, there is no clinical or tomographic evidence of fistula or recurrence. Conclusion AA has a high infiltrative capacity, suggesting a more aggressive treatment to reduce recurrence. Additionally, given limited information about the tumour, it is essential to report well‐documented cases to better understand the lesion.
