Multifocally coalescing sessile to papillary proliferations of the palatine and lingual epithelium of a New Zealand fur seal Registry #3254 (a, b). A zone of mucosal pallor surrounding the mandibular canine tooth (c). Demarcated lingual epithelial proliferation, with basophilia, and expansion of the stratum spinosum and stratum corneum (d—inset higher magnification of the lesion demonstrating cellular atypia and the presence of koilocytes—black arrowheads).
