Abstract

A 7-year-old castrated, domestic shorthair cat was presented with a 2-year history of chronic nasal discharge and sneezing. Upon presentation, bilateral mucopurulent nasal discharge and stertorous respiration were marked. Physical examination revealed a tachypnea. Oral examination was unremarkable and chest radiology was normal. Findings of nasal cytology and skull radiology were not specific and further imaging technique, endoscopic examination and histopathology was performed for a definite diagnosis. Fluid, and/or soft tissue opacity was found in bilateral nasal cavity, nasopharyngeal regions and right side tympanic bulla through the CT scan. No evidence of neoplasia was revealed. A rigid rhinoscopy, flexible bronchoscopy and otoscopy was used for the visualization of the lesions and tissue biopsy biopsy was performed for histopathology. On histopathological examination, the nasal mass consisted mainly of large numbers of plasma cells and lymphocytes. And the final diagnosis was lymphoplasmacytic rhinitis based on histopathologic examination. Long term management with oral cyclosporine (5 mg/kg, BID) was safe and successful in this cat. This is the first case report described clinical and diagnostic characteristic features of feline lymphoplasmacytic rhinitis and its clinical outcome using oral cyclosporine in Korea.

7연령의 중성화된 수컷, 단모종 고양이가 2년 동안 지속된 만성 비루와 재채기를 주증상으로 내원 하였다. 내원 당시 양측 비강내 화농성 비루가 관찰되었으며, 신체검사상 빈호흡이 확인되었다. 구강 및 흉강 방사선 검사는 정상이었으며, 두경부의 방사선 검사에서 비강과 고포의 이상이 발견되었다. 비강내 세포학 검사결과는 진단에 특이적인 소견을 제시하지 못했다. 확진을 위하여 추가적으로 컴퓨터 단층촬영검사, 비강과 비인두의 내시경 및 조직 검사가 실시 되었다. 컴퓨터 단층촬영을 통하여 양측 비강 및 비인두, 우측 고실내의 액체/연부조직 음영이 확인되었으며, 병변부의 종양성 변화는 확인되지 않았다. 비강경 및 검이경 검사를 통하여 병변부를 육안적으로 확인 할 수 있었다. 환축은 조직검사를 통하여, 림포형질세포성 비염으로 진단되었으며, cyclosporine을 이용하여 효과적으로 관리 되었다. 결론적으로 본 증례의 경우 고양이에서 발생한 림포형질세포성 비염의 임상증상과 진단, 그리고 cyclosporine을 이용한 치료 반응에 대한 국내 첫 증례보고이다.
