Summary
A rare melanotic neuroectodermal tumour of infancy (MNETI) presented as an intracranial mass in a 5-month-old boy. Surgical excision resulted in a complete recovery with an excellent long-term prognosis.
Area of Science:
- Pediatric Oncology
- Neurosurgery
- Pathology
Background:
- Melanotic neuroectodermal tumour of infancy (MNETI) is a rare, benign, congenital neoplasm.
- MNETI typically presents in the first year of life, often involving the head and neck region.
Observation:
- A 5-month-old boy presented with a bony mass behind the left ear with intracranial extension on MRI.
- Surgical exploration revealed the mass to be extradural in location.
Findings:
- Microscopic examination showed a biphasic tumor with pigmented cells in tubules and nonpigmented cells in nests, confirming MNETI.
- The patient achieved a complete tumor-free status one year post-wide local excision.
Implications:
- MNETI has an excellent prognosis, with no need for adjuvant radiotherapy or chemotherapy.
- Early diagnosis and complete surgical resection are key to favorable outcomes in MNETI.
