INTRODUCTION: Laryngeal trauma comprises less than 1% of all trauma at all sites; they are rarely associated with sports injuries. Few cases of laryngeal trauma are closed in nature. CASE REPORT: A 23-year-old male patient presented with dysphonia and neck pain but no dyspnea; the problems had started suddenly while playing rugby. He attended the emergency otolaryngology clinic of the University Hospital of the University of São Paulo, where he was given preliminary treatment and advised follow-up. The lesion completely responded to conservative management, as expected from the experience with other cases reported in the literature.
