Abstract
Background
Melanotic neuroectodermal tumour of infancy (MNTI) is a rare benign neoplasm. MNTI appears most often during the first year of life, arises predominantly in the maxilla and tends to recur. We discuss possible therapeutic options given in the literature and within our experience in three cases.
Patients
In our recent case, we used an intraoral approach to perform resection of the right-sided maxilla. Despite tumour-positive margins, there was no recurrence over the course of one year. In a previous case of MNTI, two recurrences occurred and 6 months after last resection patient received a rib graft for maxillary reconstruction. However, at the age of 7 years, the infant displayed severe maxillary hypoplasia. In a third case of MNTI, the patient was followed up after initial therapy for two decades and underwent multiple reconstruction procedures to achieve successful rehabilitation.
Conclusion
Surgical treatment of MNTI should respect vital anatomic structures to avoid gross mutilation. The need for extended and repetitive tumour resection in early childhood can lead to growth disturbances and to further multiple reconstruction procedures in adulthood. Because of the rarity of MNTI, an international database is warranted to evaluate therapies and clinical courses over decades.
