Summary
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm often recurring after diagnosis. Radical surgery is necessary for MNTI, but can cause mid-face hypoplasia.
Area of Science:
- Pediatric Oncology
- Craniofacial Surgery
- Pathology
Background:
- Melanotic neuroectodermal tumor of infancy (MNTI) is a rare, aggressive neoplasm.
- First described by Krompecher in 1918, fewer than 200 cases are documented.
- MNTI predominantly affects the maxillary region in infants.
Observation:
- This report details two infants with MNTI presenting in the maxillary region at 6 and 8 weeks old.
- The tumors caused significant destruction of the mid-face despite the absence of other systemic symptoms.
- Rapid recurrence was observed within the first year post-diagnosis, even after radical surgical intervention.
Findings:
- Clinical and histological findings indicate locally malignant growth patterns.
- Radical resection of the primary tumor and subsequent recurrences is the established therapeutic approach.
- Long-term follow-up revealed mid-face hypoplasia due to impaired germinal development after maxillary hemisection.
Implications:
- Early and aggressive surgical management is crucial for MNTI.
- Understanding the potential for growth inhibition is vital for long-term patient care.
- Further research into less invasive treatment modalities for MNTI is warranted.
