Abstract

Enzootic nasal adenocarcinoma (ENA) is a viral-associated tumor of the secretory epithelium of the nasal passages of small ruminants. The tumor is locally invasive but not metastatic. Although disease prevalence (up to 15%) and geographic distribution have been reported in the literature throughout most of the world (except Australia and New Zealand), the disease has until now remained unreported in Jordan. In this report, we describe the occurrence, clinical signs, radiographic signs and pathological features of the disease in a series of cases in Awassi sheep (3 cases) and Damascus breed goats (2 cases) for the first time in Jordan. Overall, the affected animals were adults (3-5 years of age), all females, with variable degrees of facial and nasal deformities resulting in difficulty in respiration. Radiographic examination of the skull revealed soft tissue density mass originating in the nasal turbinate and invading the surrounding nasal structures. Cytological examination of fine needle aspirate indicated low-grade carcinoma. All animals were humanely euthanized and the nasal passages were explored. Variable size masses were removed and histopathological examination confirmed the diagnosis of enzootic nasal adenocarcinoma.
