Abstract

STUDY DESIGN: Case report.

INTRODUCTION: De novo giant pleomorphic adenoma is a rare tumor of the parapharyngeal space (PPS). Tumors of the PPS can grow to a large size, compromising the space of the upper aerodigestive tract. However, involvement of the paravertebral region is unexpected. In extremely exceptional circumstances, these tumors can produce spinal deformity.

CASE REPORT: A 25-year-old man presented with a longstanding mass in the neck and oral cavity. He had complaints of dysphagia, snoring, and restricted neck movements because of the large size of the tumor. Imaging showed a large mass occupying the PPS extending to the paravertebral region and causing deformity of the cervical spine. Excision was done uneventfully via a minimal access transcervical approach. Residual spinal deformity dealt with postoperative physiotherapy with improvement in lordosis and lateral tilt. No tumor recurrence occurred till 26 months of follow-up.

CONCLUSION: Tumors of the PPS can grow to a large size and involve the neck and PPS, even causing spinal deformity. Careful evaluation is required for ascertaining the origin of the tumor and deciding the treatment plan.
