Summary
This report details the first intraosseous plexiform schwannoma of the maxilla, an exceptionally rare benign neurogenic tumor. Accurate diagnosis is crucial to differentiate it from potentially malignant lesions.
Area of Science:
- Oral and Maxillofacial Surgery
- Neurosurgery
- Oncology
Background:
- Schwannomas, benign peripheral nerve sheath tumors, are uncommon within jaw bones.
- Plexiform schwannoma is a rare variant characterized by a plexiform growth pattern.
Observation:
- This case presents the first documented intraosseous plexiform schwannoma originating in the maxilla.
- The tumor is a benign neurogenic neoplasm requiring surgical treatment.
Findings:
- Plexiform schwannoma exhibits multinodularity and intraneural growth.
- While benign, incomplete excision can lead to recurrence.
Implications:
- Distinguishing plexiform schwannoma from plexiform neurofibroma is critical due to the latter's high malignant potential.
- Accurate histopathological diagnosis guides appropriate surgical management and prevents misdiagnosis of potentially malignant conditions.
