Abstract

The right third eyelid of an adult female brown bear (Ursus arctos) was swollen and removed. Histopathology revealed a tumor exhibiting proliferation with mild infiltration, consisting of multi-stratified glandular structures of the innermost laminal neoplastic cells and the basaloid neoplastic cells, and with eosinophilic thick basal lamina material around the glandular structures. Both types of neoplastic cells exhibited moderate anisokaryosis, and mitotic figures were observed in the basaloid neoplastic cells. The laminal neoplastic cells were cytokeratin (CK) 8/18-positive. In contrast, the basaloid neoplastic cells were CK14- and p63-positive, but α-smooth muscle actin- and calponin-negative. The case described herein is the first report of basal cell adenocarcinoma in the gland of the third eyelid of a bear.
