A Case of Adult-type Rhabdomyoma of the Larynx

Abstract

Extracardiac rhabdomyomas are rare benign tumors that originate from the striated muscle. Histologic analysis is essential for definitive diagnosis. The curative treatment for rhabdomyomas is surgical excision. We report a case with adult-type rhabdomyoma of the larynx. A 43-year-old female patient presented to us with a one-year history of hoarseness. Flexible laryngoscopic examination showed a smooth submucosal swelling of the left false cord. The tumor was removed using microlaryngeal surgical techniques. Histologic examination revealed an adult-type rhabdomyoma. At the 6-month follow-up, she exhibited no evidence of tumor recurrence and her voice was normal. Long-term follow-up is necessary, as recurrence can occur several years later.
