Adenoid cystic carcinoma of trachea masquerading as papillary thyroid cancer - a case report

Abstract

Introduction: Thyroid nodules are common clinical entity. Though indolent in nature, they can be invasive too. However, tracheal tumours are relatively rare and come into clinical picture when patients show symptoms of tracheal obstruction.

Case report: We report a 45 year old female who presented with cytology proven papillary carcinoma thyroid with clinical and radiological evidence of tracheal involvement. Patient underwent total thyroidectomy along with en bloc segmental tracheal resection with end to end anastomosis. However the pathology revealed adenoid cystic carcinoma of trachea.

Conclusion: Adenoid cystic carcinomas of trachea are rare tumors and they can present as thyromegaly secondary to thyroid involvement. Surgeons should have a high index of suspicion for diagnosis. Surgical resection forms the mainstay of treatment.
