Summary
Surgical removal of a malignant-appearing melanotic neuroectodermal tumor of infancy (MNTI) in a 2-month-old boy resulted in an excellent prognosis. Long-term follow-up showed no recurrence or developmental handicap.
Area of Science:
- Pediatric Oncology
- Neurosurgery
- Pathology
Background:
- Melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm typically affecting infants.
- While often benign, MNTI can exhibit malignant histological features, raising concerns about prognosis.
Observation:
- A 2-month-old boy presented with a right temporal MNTI, histologically diagnosed as malignant.
- The child underwent complete surgical excision of the tumor.
Findings:
- Post-operative follow-up up to age 5 years revealed no evidence of tumor recurrence or metastasis on neuroradiological evaluation.
- Neurological and psychological assessments at age 5 showed no resulting handicap.
Implications:
- Complete surgical resection is an effective primary treatment for MNTI, even with malignant histological features.
- MNTI, despite concerning histology, can have an excellent prognosis following adequate surgical management.
- This case highlights the importance of thorough surgical treatment and long-term surveillance for MNTI.
