| Popis: | 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. Enzootski nazalni adenokarcinom (ENA) je tumor sekrecijskog epitela nazalnih putova etiološki povezan s virusom u malih preživača. Tumor je lokalno invazivan, ali ne metastazira. Premda postoje izviješća o njegovoj pojavnosti (do 15 %) i geografskoj rasprostranjenosti gotovo u cijelom svijetu (osim Australije i Novog Zelanda), u Jordanu je ostao nezamjećen. U ovom radu opisana je pojavnost, klinički znaci, rendgenološki nalazi i patološke promjene tog tumora u nizu slučajeva u Awassi pamine ovaca (3 slučaja) i pasmine koza damask (2 slučaja) prvi puta u Jordanu. Općenito, životinje s tumorom bile su odrasle (u dobi od 3-5 godina), sve su bile ženke s različitim stupnjevima deformacija lica i nosa, koje su rezultirale otežanim disanjem. Rendgenološkim pregledom lubanje otkrivena je masa mekane gustoće tkiva koja je potjecala iz nazalne školjke, a koja invadira okolne nazalne strukture. Citološkom pretragom aspirata tkiva pomoću tanke igle, otkrivena je niska invazija karcinomom. Sve su životinje eutanazirane sukladno s etičkim normama, a nosni putovi su pregledani. Mase tkiva različite veličine bile su uklonjene, a histopatološka pretraga je potvrdila dijagnozu enzootskog nazalnog adenokarcinoma. |
