Three days prior to evaluation, the clinical signs had worsened, including 1 episode of collapse.<\/jats:p>\nCLINICAL FINDINGS<\/jats:bold> Thoracic radiography and CT revealed a well-delineated soft tissue mass, located approximately 1.5 cm cranial to the carina and occupying almost 90% of the tracheal lumen. A CBC and serum biochemical analysis were performed, and all results were within reference limits.<\/jats:p>\nTREATMENT AND OUTCOME<\/jats:bold> Tracheoscopy confirmed the presence of a broad-based bilobate mass that was protruding from the right dorsal aspect of the trachea and occupied almost the entire tracheal lumen. The mass was successfully resected by endoscopic-guided electrocautery ablation. Findings of histologic evaluation were consistent with a diagnosis of liposarcoma. Immediately following the ablation procedure, the previously noted clinical signs of respiratory tract disease resolved. On follow-up examination 12 months later, no regrowth of the mass was evident on thoracic helical CT and tracheoscopy.<\/jats:p>\nCLINICAL RELEVANCE<\/jats:bold> Endoscopic-guided electrocautery ablation of tracheal liposarcoma was a safe and effective minimally invasive treatment for the dog of this report. The procedure was brief and appeared to be well tolerated, resulting in immediate improvement of clinical signs.<\/jats:p>","DOI":"10.2460\/javma.252.5.581","type":"journal-article","created":{"date-parts":[[2018,2,20]],"date-time":"2018-02-20T15:23:03Z","timestamp":1519140183000},"page":"581-585","source":"Crossref","is-referenced-by-count":8,"title":["Use of endoscopic-guided electrocautery ablation for treatment of tracheal liposarcoma in a dog"],"prefix":"10.2460","volume":"252","author":[{"given":"Anne-Sophie","family":"Bua","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana\u00efs","family":"Combes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Maitre","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yannick","family":"Bongrand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1272","reference":[{"key":"ref1","series-title":"J Am Vet Med Assoc","doi-asserted-by":"publisher","first-page":"385","DOI":"10.2460\/javma.233.3.385","article-title":"What is your diagnosis?","volume":"233","author":"Smith","year":"2008"},{"key":"ref2","series-title":"J Am Vet Med Assoc","first-page":"1097","article-title":"Tracheal mast cell tumor in a dog","volume":"180","author":"Harvey","year":"1982"},{"key":"ref3","series-title":"J Am Vet Med Assoc","doi-asserted-by":"publisher","first-page":"1299","DOI":"10.2460\/javma.2005.226.1299","article-title":"What is your diagnosis?
