Tracheoesophageal puncture (TEP) is a voice restorative option adopted by many head and neck cancer patients following laryngectomy. Though generally safe, TEP may develop leakage. Lenvatinib is a tyrosine kinase inhibitor (TKI) with anti-tumoral activity against head and neck malignancies.TKIs, including lenvatinib, have been associated with organ perforation or fistula formation. There remains a paucity of literature on the association between lenvatinib and TEP leakage. In this report, we described a patient with adenoid cystic carcinoma of the larynx who had a TEP. After approximately two weeks of treatment with lenvatinib, the patient developed a leakage of TEP. Despite several interventions, the patient died three months afterward due to a retropharyngeal abscess secondary to Fusobacterium nucleatum. To our knowledge, this is the first report of fatal lenvatinib-associated TEP leakage. Clinicians should be cognizant of a potentially rapid development of this complication when prescribing TKI for patients with TEP.
