Recurrent plexiform schwannoma in vestibular mucosa

Area of Science:

• Oral Pathology
• Neurosurgery
• Oncology

Background:

• Schwannoma, also known as neurilemmoma, is a benign neoplasm originating from the peripheral nerve sheath.
• Intraoral schwannomas are rare, with plexiform schwannoma being an uncommon variant.
• The facial nerve branches are an infrequent site for intraoral schwannoma development.

Observation:

• A case of multiple intraoral plexiform schwannomas is presented in a young male patient.
• The tumors were located in an unusual site: the vestibular mucosa, arising from facial nerve branches.
• The clinical presentation and diagnostic process are detailed.

Findings:

• Histological examination confirmed the diagnosis of plexiform schwannoma.
• The benign nature of the neoplasm was established.
• Surgical treatment was considered based on the definitive histological diagnosis.

Implications:

• This case expands the understanding of schwannoma locations within the oral cavity.
• It underscores the importance of considering peripheral nerve sheath tumors in intraoral masses.
• The discussion of surgical management provides insights for clinical practice involving similar rare presentations.
