Critical Tracheal Stenosis From Adenoid Cystic Carcinoma During Pregnancy: Case Report

( J Clin Anesth . 2021;77:110620) The complication of full-term pregnancy by malignancy occurs in an estimated 0.1% of cases. Adenoid cystic carcinoma (ACC) is itself a rare cancer of the head and neck, amounting to just 0.2% of tracheal tumors. As an aggressive carcinoma, ACC produces critical symptoms including airway obstruction often preceded initially by coughing, stridor, dyspnea, and hemoptysis. This case report advances the literature with documentation of the most extensive ACC during pregnancy with advancing tracheal stenosis reported to date, and critical methods by which a difficult airway was managed during cesarean delivery (CD).
