Neoplasms arising in the larynx may cause severe upper airway obstruction and present diagnostic and therapeutic challenges due to the anatomical and functional constraints of this region. An 11\u2010year\u2010old neutered male mixed\u2010breed dog was evaluated for a one\u2010month history of progressive upper airway obstruction characterized by dyspnea, tachypnea, and dysphagia. Clinical examination revealed a solitary mass protruding into the laryngeal lumen in the arytenoid region. Surgical excision was performed, and intraoperative frozen section evaluation indicated compromised surgical margins. Definitive histopathology confirmed an invasive SCC. Adjunct electrochemotherapy was applied following identification of compromised surgical margins, and the dog showed favorable short\u2010term clinical recovery following surgery. No evidence of recurrence or metastasis was observed during a three\u2010month follow\u2010up period. This case highlights the clinical relevance of laryngeal SCC in dogs and emphasizes the importance of thorough clinical examination and early detection, as well as the integration of clinical evaluation, histopathology, and intraoperative margin assessment in the management of upper airway neoplasms. The combined use of surgical excision, frozen section analysis, and adjunct electrochemotherapy may be considered a potential therapeutic approach in anatomically constrained regions where complete tumor removal is limited.<\/jats:p>","DOI":"10.1155\/crve\/5935429","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T09:52:42Z","timestamp":1783677162000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Invasive Squamous Cell Carcinoma of the Larynx in a Dog"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6312-9579","authenticated-orcid":false,"given":"Edenilson Don\u00e1","family":"Frigerio","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samira das Merc\u00eas Saboia","family":"Bezerra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu\u00edsa Husz","family":"Toledo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruna Rodrigues Ferreira","family":"Sengue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4956-8145","authenticated-orcid":false,"given":"Maria Eduarda Roselli","family":"Silv\u00e9rio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2938-7267","authenticated-orcid":false,"given":"Igor Luiz Salardani","family":"Senhorello","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3462-4722","authenticated-orcid":false,"given":"Alexandre Lima","family":"de Andrade","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3759-707X","authenticated-orcid":false,"given":"Daniela Bernadete","family":"Rozza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7701-6375","authenticated-orcid":false,"given":"Gisele Fabrino","family":"Machado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,10]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"crossref","DOI":"10.1002\/9781119181200","volume-title":"Tumors in Domestic Animals","author":"Meuten D.
