Abstract

A 15-year-old, castrated male shih-tzu dog was referred to Veterinary Medical Teaching Hospital of Gyeongsang National University due to dyspnea, anorexia, depression of 1 week's duration. On thoracic radiography, triangular shaped soft tissue opacity mass presented in the left cranial lung lobe region. On computed tomography, there was a $3.8{\times}2.5$ cm mass in the left thoracic cavity, which was lobulated and adhered to ventral pleural surface. Histopathologically, the neoplastic cell population consisted of a lot of lymphocytes and a few of Hassal's corpuscles. The immunohistochemistry, lymphocytes were diffusely positive for CD3 and focal positive $CD79{\alpha}$. Based on gross, histologic, and immunohistochemical findings, the neoplasm was diagnosed a lymphocyte predominant thymoma.
