Infiltrative odontogenic myxoma of the posterior maxilla: Report of a case

Myxomas of the head and neck are rare tumors of uncertain histogenesis. Odontogenic myxomas in maxilla are less common but behave more aggressively, as it spreads through maxillary antrum. It therefore reaches considerable size before being detected. The current case arouses particular interest due to the rapid growth and infiltrating nature of the lesion in a 25-year-old female patient, who denied any leading symptoms, even with the lesion involving extensively. Radiographic and microscopic similarities to a number of entities make diagnostic interpretation of odontogenic myxoma challenging. Therefore sound knowledge of clinical, radiographic and histopathologic features is important to establish an appropriate treatment aimed at a good clinical course and patient cure.
