OBJECTIVE: Description of transendoscopic electrosurgical treatment of a pulmonary granular cell tumor in a horse. STUDY DESIGN: Case report. ANIMALS: A 12-year-old Standardbred mare. METHODS: After endoscopic examination and transendoscopic biopsy, a granular cell tumor nodule was removed transendoscopically from the right principal bronchus of the sedated horse (0.02 mg/kg detomide intravenous) with a monopolar electrosurgical wire snare. Two days later, the surgical area was irradiated transendoscopically using a Nd-YAG laser. RESULTS: After surgery, the horse had no further signs of respiratory disease. Clinical and endoscopic examination and radiography performed 4 times during the following 2 years showed no evidence of recurrence. CONCLUSIONS: Transendoscopic electrosurgical removal of nodular masses located intraluminally in the principal bronchi is possible on the sedated standing horse. CLINICAL RELEVANCE: Granular tumors are rare lung neoplasms that lead to unspecific signs of a low airway disease. Diagnosis requires endoscopic examination of the large bronchi. Early intraluminal stages can be treated transendoscopically. Copyright 2002 by The American College of Veterinary Surgeons
