Cervical sympathetic chain schwannoma: a case report

Area of Science:

• Head and Neck Surgery
• Surgical Oncology
• Neuro-oncology

Background:

• Parapharyngeal space tumors are uncommon and present unique surgical challenges due to complex anatomy.
• A diverse range of histological tumor types can arise in this region.
• Tumors can grow significantly before detection, complicating diagnosis and treatment.

Observation:

• A rare case of schwannoma originating from the cervical sympathetic chain is reported.
• The schwannoma presented as a clinically evident mass in the parapharyngeal space.
• This case underscores the importance of considering neurogenic tumors in parapharyngeal masses.

Findings:

• Schwannoma, a tumor of nerve sheath cells, can arise from the cervical sympathetic chain.
• The parapharyngeal space is an unusual but possible location for such presentations.
• Diagnostic imaging and surgical exploration are crucial for definitive diagnosis.

Implications:

• This case expands the differential diagnosis for parapharyngeal space masses.
• Understanding the origin of these rare tumors aids surgical planning and patient management.
• Further research into rare neurogenic tumors in the head and neck is warranted.
