Abstract

It is difficult to detect and diagnose a mass at the tongue base, particularly if the mass is located under normal appearing mucosa. Computed tomography (CT), particularly post-contrast images, is useful to evaluate a tongue mass and adjacent structures including cervical lymph nodes. Nevertheless, a definitive diagnosis of a mass is obtained by histopathological examination. In this case, we describe a mass arising from the tongue body to the root in a dog. The patient was referred with ptyalism and an eating disorder. An oral examination was performed, and decreased tongue motility was observed. CT scanning was performed, and a lingual mass was detected. A lingual mass sample was collected by biopsy at the postmortem 2 months later. A histopathological examination was performed, and the lingual mass was diagnosed as squamous cell carcinoma.

혀 뿌리 부위의 종양, 특히 종양이 정상으로 보이는 점막 아래에 위치해 있는 경우 발견하고 진단하기가 어렵다. 전산화단층촬영법, 특히 조영후 영상은 혀의 종양을 평가하고 경부 림프절을 포함한 인근 조직을 평가하기에 유용하다. 그러나 종양을 확진하기 위해서는 조직병리검사가 필요하다. 본 증례는 개에서 혀의 뿌리부터 몸통에 걸쳐 종양이 발생하였으며 환자는 유연과다 및 섭식장애 증상으로 전원되었다. 구강검사 결과 혀의 운동성 장애가 관찰되었으며 전산화단층촬영으로 혀 종양이 확인되었다. 2달 뒤 사후에 개의 혀에서 조직을 채취하여 조직병리검사를 실시한 결과 혀의 종양은 편평세포암종으로 진단되었다.
