Maxillary myxoma in children.

Myxoma of the maxilla is a rare, slowly growing, benign mesenchymal tumor. Pathologically, it may be difficult to differentiate from other tumors with myxoid stroma and is occasionally misinterpreted as malignant. This tumor is particularly uncommon in children; in a search of the literature, we were able to document only 17 cases of myxomas in the maxilla in patients aged 14 years or less. This report on two children with myxoma of the maxilla emphasizes the importance of including myxoma in the differential diagnosis of children with maxillofacial tumors, and underlines the difficulties in making a correct diagnosis.
