Abstract
An eleven-year-old, female goat was presented for evaluation of breathing difficulties and epistaxis. Radiographs and computed tomographic (CT) examination of the head revealed the presence of a space-occupying lesion involving the right nasal passage and invading the cranial vault and retrobulbar space. Histologic examination and detection of viral genome from the nasal mass led to the diagnosis of nasal transitional carcinoma with concomitant infection with Enzootic Nasal Tumor Virus (ENTV-2). In this case report, the presence of a nasal transitional carcinoma is described in a goat; a very rare tumor which, to the authors’ knowledge, has not been previously reported in goats. Reverse transcription polymerase chain reaction (RT-PCR) detected the genome of ENTV-2 within the neoplastic tissue, suggesting an infectious etiology.
Highlights
An eleven-year-old, female goat was admitted to the Veterinary Hospital of the Faculty of Veterinary Medicine of Ghent University with stertorous breathing and bilateral epistaxis, which started one week prior to the presentation
This is the first case report with thorough radiographic and computed tomographic (CT)-description of a transitional carcinoma of the nasal passages in a goat associated with Enzootic Nasal Tumor Virus 2 (ENTV-2) infection
ENTV infections are typically associated with the induction of nasal adenocarcinomas (Özmen et al, 2010), some authors use the broader term ‘enzootic intranasal tumor’ (De las Heras et al, 1995)
Summary
An eleven-year-old, female goat was admitted to the Veterinary Hospital of the Faculty of Veterinary Medicine of Ghent University with stertorous breathing and bilateral epistaxis, which started one week prior to the presentation. The goat had been treated with dexamethasone and antibiotics without improvement. She did not show any clinical signs. The goat had been kept as a companion animal together with a second goat for the last decade in the countryside between Brussels and Charleroi. The second goat did not show any clinical signs. Mild hyperbilirubinemia, lymphocytopenia, monocytopenia and eosinopenia were detected
