Rhabdomyoma, a benign soft tissue tumor most often seen in the heart, rarely occurs elsewhere. We report a rare case of rhabdomyoma of the larynx. A 50-year-old man with a 3-year history of hoarseness was found in endoscopic examination and computed tomography to have a well-defined lobulated submucosal right arytenoid mass extending to the false vocal cord. It showed slight contrast enhancement, intermediate intensity in the T1-weighted magnetic resonance imaging (MRI), and intermediate to partially high intensity in T2-weighted MRI. We conducted tracheostomy and direct laryngoscopy biopsy. The histopathological diagnosis was rhabdomyoma, and the tumor was resected via lateral pharyngotomy. The man developed a recurrent tumor and underwent reoperation 4 months after the first surgery, but no further recurrence has been seen in 19-month follow-up. We bibliographically review clinical characteristics, diagnosis, and treatment of rhabdomyoma.
