A six-year-old dog that presented with signs of nasal cavity disease was diagnosed with nasal carcinoma. Another dog from the household had been diagnosed with the same condition a few months prior. Samples of nasal mucosa were collected postmortem to investigate possible aetiological factors. Histopathological examination confirmed the diagnosis and revealed the presence of a parasite within the neoplastic tissue. The parasite was identified as a Linguatula serrata nymph based on in its morphological characteristics. This is the first report of nasal carcinoma with concurrent linguatulosis in a dog. It is proposed that inflammation associated with L serrata infestation may be a predisposing factor in the development of nasal cavity neoplasia.
