Tracheal adenoid cystic carcinoma: A reported case and review of literature.

remains the primary treatment, but optimal postoperative radiotherapy regimens are still being explored to minimize localrecurrence. This is a case of ACC of the trachea. An individualized radiotherapy regimen was meticulously planned aftersurgery. This tailored approach significantly impacted the patient’s outcomes.Case Report: A 49-year-old female with history of progressive dyspnea and cough that was unresponsive to conventionaltreatments over 6 months. Flexible bronchoscopy revealed an obstructing mass in the upper trachea, and biopsy confirmedthe diagnosis of adenoid cystic carcinoma. Imaging ruled out distant metastases. The patient underwent tracheal sleeveresection, followed by adjuvant radiation therapy using Volumetric Modulated Arc Therapy (VMAT) and 6-megavoltage(MV) radiography. The patient tolerated the treatment well, with no significant acute or late toxicities. Follow-up imagingstudies have shown no evidence of recurrence at 6 years post-treatment.Conclusion: Tracheal ACC is a rare but distinct entity that requires prompt recognition and multimodality managementfor optimal outcomes.
