Intraluminal tracheal lipoma as a rare cause of dyspnoea in a dog

Background: Tracheal tumors are rarely diagnosed in veterinary medicine and the majority of tracheal neoplasia reported in adult dogs are malignant. Intratracheal lipoma has not been previously reported in the veterinary literature. Case presentation: A 7-year-old Briard dog was evaluated for inspiratory dyspnoea and an inspiratory wheeze. Cervical radiographs and tracheoscopic examination revealed an intratracheal mass that was surgically removed. The dog has been asymptomatic after the surgery. Conclusions: Based on histopathology, the mass was diagnosed as lipoma. To the authors' knowledge, this is the first published report of an intratracheal lipoma in the veterinary literature.Peer reviewe
