title: Maxillary bone myxoma.
abstract: BACKGROUND
  Maxillary bone myxoma is a rare benign mesenchymal tumor, slow-growing but locally aggressive. Pathogenesis remains disputed.
  
  
  OBJECTIVE
  To study the clinical, radiological and histological features and treatment of maxillary myxoma, based on a pediatric case report.
  
  
  METHODS
  An infant of two and a half months presented with endonasal tumor extending to ethmoid. Surgical excision was performed on an endonasal approach. Myxoma was diagnosed by histologic examination of the surgical specimen, whereas initial biopsy had suggested fibrous dysplasia. No recurrence was observed after two and a half years' surveillance.
  
  
  CONCLUSIONS
  Positive diagnosis of maxillary myxoma is histological. Treatment is primarily surgical. Strict long-term surveillance is required because of the high risk of recurrence.
