Bilateral recurrent adult rhabdomyomas of the pharyngeal wall

Adult rhabdomyomas of the head and neck are uncommon benign skeletal muscle tumors. Only a few cases occurring in the pharyngeal wall have been descri bed in the world literature. We present a case of recurrent bilateral rhabd omyomas in the pharynx and discuss the clinicopathological features of this lesion, comparing it to those of other neoplasms from which it must be dif ferentiated. To our knowledge, bilaterality of this type of lesion has not been described previously. Although adult rhabdomyomas have a distinct hist ology, they often are mistaken for a variety of other lesions, particularly granular cell tumor.
