Canine laryngopharyngeal rhabdomyoma resembling an oncocytoma: light microscopic, ultrastructural and comparative studies.

ABSTRACT

A laryngopharyngeal rhabdomyoma was diagnosed in a four-year-old dog with clinical signs of upper respiratory obstruction. In people, rhabdomyomas have a predilection for the head and neck area. Features of this tumor were compared with an oncocytoma with which it may be confused.
