Rhabdomyoma of the pharyngeal wall.

Rhabdomyoma is a rare benign tumor of skeletal muscle, and the head and neck region is the most common extracardiac area for these tumors to occur. Twenty-one cases have previously been reported, and this report, "A Rhabdomyoma of the Pharyngeal Wall," brings the total to 22. Pathologically, these tumors show abundant polygonal skeletal muscle cells with demonstrable cross striations. Differential diagnosis of these tumors has included granular cell myoblastoma and rhabdomyoscarcoma. Treatment is usually complete excision.
