[Odontogenic myxoma of nasosinusal localization in a pediatric patient]

In the present study we report and discuss a case of odontogenic myxoma in a 13-month-old patient. Only two other reports have been published in the literature describing the occurrence of this type of tumor at an earlier age. Odontogenic myxoma is a benign mesenchymal neoplasm of the maxilla more common between the third and fourth decades of life. The case here reported is exceptional as it presents in an infant and, although some cases have been reported in the literature, this type of tumor is rare in early childhood. The most common locations include the ascending ramus and the angle of the jaw, although these tumors may also affect the upper maxilla, in which case they may involve the maxillary sinus. According to the review of the literature, these tumors show a recurrence rate of about 25%. Consequently, after the intraoperative clinical examination of the lesion and the assessment of the initial suspected diagnosis by means of intraoperative biopsy under general anesthesia, we carried out the resection of the tumor with wide margins at some points of the tumor location.
