A dog presenting with weight loss and displacement of the heart to the right was diagnosed as having a thymoma by transthoracic fine‐needle aspiration biopsy. The cytological findings are described and correlated with the histological findings. Cytologically the lesion contained numerous large clusters of neoplastic epithelial cells with scant basophilic cytoplasm, and scattered, well‐differentiated lymphocytes. Histologically the thymoma was composed of predominantly spindle‐shaped epithelial cells arranged in broad sheets or forming sworling and storiform patterns. Some lobules contained lymphoid cells.
