RESUMO
Odontogenic myxomas (OMs) are rare, benign, slow-growing tumors that may arise in the maxilla. They are known to have a female predilection and present as a painless mass commonly in the second or third decade of life, comprising 3-6% of all odontogenic tumors. They show a locally aggressive behavior, are radioresistant tumor and hence the need for early recognition and surgical resection. A high rate of recurrence has also been noted owing to its infiltrative pattern of growth and lack of capsule. Clinical and radiological aspects of maxillary OMs are not conclusive hence it is necessary to have a histopathological exam for the final diagnosis. We present a case of OM involving the maxilla in a 51-year-old female patient. The various histopathological differentials are also discussed.
