Abstract | This report deals about a rare case of nasal chondrosarcoma in a dog. A 10 years old male German shepherd dog was brought to the Teaching Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal with the history of progressive growth in the right nostril for the last 3 months. Clinically, there was a reddish pedunculated mass completely obliterating the right nasal passage and the tumour mass protruding through right nostril. Radiography of rostral view revealed a radio opaque mass in the right nostril. The fine needle aspiration and punch biopsy samples were collected for cytological and histopathological diagnosis respectively. In cytology, cluster of cells revealed pleomorphism, anisocytosis, anisokaryosis and mitotic figures were observed. Histopathologically, proliferating pleomorphic chondrocytes with increased mitotic activity and central area of necrosis were noticed. Sublingual lymphnodes sections also showed presence of pleomorphic chondrocytes. Surgical excision was not advised due to its extensive growth in the entire nasal passage, metastasis into sublingual lymphnodes and aggressive nature of tumour. The specific chemotherapy could not be undertaken due to lack of owner consent.
