Abstract

A 10-year-old female collared peccary (Tayassu tajacu) was referred due to a large palpable mass in caudal abdomen. Physical examination revealed a firm and freely moveable mass (15 ${\times}$ 9 cm) in the right side of caudal abdomen. Thoracic radiographic findings revealed a few well circumscribed nodules. This case was diagnosed as mammary gland squamous cell carcinoma with pulmonary metastasis based on histopathological and immunohistochemical findings. This type of mammary gland tumors is uncommon in wild animals. The patient survived for one month after the diagnosis. This is the first case report of mammary squamous cell carcinoma in a collard peccary and the second case report of metastatic carcinoma to lung in a collared peccary.

10년령의 암컷 collared peccary (Tayassu tajacu)가 후복부의 종양을 주증으로 내원하였다. 신체 검사상에서, 우측 하복부에 위치하고 있는 단단하고 고정되어있지 않는 종양 (15 ${\times}$ 9 cm)이 확인되었다. 흉부 방사선 검사 상에서 경계가 명확한 결절이 관찰되었으며, 이는 폐 전이 소견으로 보여졌다. 본 증례는 조직검사와 면역조직검사를 통하여 폐 전이를 동반한 유선 편평 세포 선암종으로 진단되었다. 야생 동물에서, 유선 편평 세포 암종은 매우 드문 유선 종양이다. 페커리는 진단 한달 후에 폐사하였다. 본 증례 보고는 페커리에서 처음 보고되는 유선 종양 케이스이며 두번째로 보고되는 폐 전이성 선암종이다.
