Total laryngectomy and permanent tracheostomy for treatment of laryngeal rhabdomyosarcoma in a dog.

An extensive, laryngeal tumor was identified in a nine-year-old, spayed female, mixed-breed dog. Clinical staging of the tumor included computed tomography. Six days prior to surgery, a percutaneous gastrostomy tube was placed under endoscopic guidance. Surgical treatment included total laryngectomy and permanent tracheostomy. The histologic diagnosis of the tumor was rhabdomyosarcoma. There were no major postoperative complications, and there have been no signs of local recurrence, metastatic disease, or long-term complications associated with the surgical procedure during an 18-month follow-up period.
