Insights
Melanotic neuroectodermal tumour of infancy, a rare benign pigmented tumor, can present atypically. This case highlights a unique instance associated with an erupted primary tooth in an infant.
Area of Science:
- Oral Pathology
- Pediatric Oncology
- Dermatology
Background:
- Melanotic neuroectodermal tumour of infancy (MNTI) is a rare, benign, pigmented neoplasm.
- It predominantly affects infants, typically within the first year of life.
- MNTI commonly occurs in the head and neck region, particularly the maxilla.
Observation:
- A 7-month-old boy presented with an atypical MNTI.
- The tumour was notably associated with an erupted primary tooth.
- This presentation deviates from typical MNTI occurrences.
Findings:
- The case details the clinical presentation, radiographic imaging, and histological characteristics of the atypical MNTI.
- Diagnostic features were analyzed to understand this rare variant.
- The tumour was confirmed to be benign despite its unusual presentation.
Implications:
- This case expands the understanding of MNTI's varied clinical manifestations.
- It emphasizes the importance of considering MNTI in infants with oral masses, even with unusual associations like erupted teeth.
- Optimal surgical management and follow-up strategies for atypical MNTI are discussed.
Abstract:
Melanotic neuroectodermal tumour of infancy is a rare benign pigmented tumour that typically appears in the first year of life. We report an atypical presentation of this tumour, associated with an erupted primary tooth in a 7-month-old boy. We discuss the clinical, radiographic and histologic features of this rare tumour, as well as its surgical management and the follow-up treatment plan.
