Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Summary

Maxillary teratoma, a rare congenital tumor, can present as a large intraoral mass. Surgical excision in a 10-year-old boy resulted in an uneventful recovery with no recurrence after two years.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Pediatric Oncology
  • Developmental Biology

Background:

  • Teratomas are rare tumors containing elements from all three embryonic germ layers.
  • Intraoral teratomas, particularly in the maxilla, are exceptionally uncommon congenital anomalies.
  • While typically benign, malignant transformation of teratomas has been reported in adults.

Observation:

  • A 10-year-old male presented with a substantial, rapidly growing mass on the right side of his maxilla.
  • The congenital intraoral teratoma measured significantly in size, impacting the maxillary region.
  • Clinical examination revealed a large tumor requiring surgical intervention.

Findings:

  • Surgical excision of the maxillary teratoma was successfully performed under general anesthesia.
  • Histopathological analysis confirmed the presence of all three embryonic germ layers, characteristic of a teratoma.
  • The tumor was predominantly composed of fibrous tissue.

Implications:

  • This case highlights the importance of early diagnosis and surgical management of pediatric maxillary teratomas.
  • Complete surgical resection is crucial for achieving favorable outcomes and preventing recurrence.
  • The successful management of this rare pediatric case contributes to the understanding of teratoma behavior in the maxillofacial region.
