Introduction:
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.
Case Report:
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.
Conclusion:
Positive diagnosis of maxillary myxoma is histological. Treatment is primarily surgical. Strict long-term surveillance is required because of the high risk of recurrence.

The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
